Mia Herkt 3cf8053b75 - Update to v1.20.0 (go.d.plugin v0.15.0) 
Breaking Changes:
  * Removed deprecated bash collectors apache, cpu_apps, cpufreq,
    exim, hddtemp, load_average, mem_apps, mysql, nginx, phpfpm,
    postfix, squid, tomcat. If you were still using one of these
    collectors with custom configurations, you can find the new
    collector that replaces it in the supported collectors list.
Improvements:
  * Host labels:
    + Added support for host labels
    + Improved the monitored system information detection.
      Added CPU freq & cores, RAM and disk space.
    + Started distinguishing the monitored system's (host)
      OS/Kernel etc. from those of the docker container's
    + Started creating host labels from collected system info
    + Started passing labels and container environment variables
      via the streaming protocol
    + Started sending host labels via exporting connectors
    + Added label support to alarm definitions and started
      recording them in alarm logs
    + Added support for host labels to the API responses
    + Added configurable host labels to netdata.conf
    + Added kubernetes labels
  * New collectors:
    + eBPF kernel collector
    + CockroachDB
    + squidlog: squid access log parser
  * Collector improvements:
    + apps.plugin: Created dns group, improved database group,
      improved ceph & samba groups

Fri May 3 15:08:20 UTC 2019 - Martin Herkt <9+suse@cirno.systems>
- Update to v1.14.0
The release introduces major additions to Kubernetes monitoring,
with tens of new charts for Kubelet, kube-proxy and coredns
metrics, as well as significant improvements to the netdata
helm chart.
Two new collectors were added, to monitor Docker hub and Docker
engine metrics.
Finally, v1.14 adds support for version 2 cgroups, OpenLDAP
over TLS, NVIDIA SMI free and per process memory and configurable
syslog facilities.
Bug Fixes:
* Fixed problem autodetecting failed jobs in python.d plugin.
It now properly restarts jobs that are being rechecked,
as soon as they are able to run.
* CouchdDB monitoring would stop sometimes with an exception.
Fixed the unhandled exception causing the issue.
* The netdata api deliberately returned http error 400 when
netdata ran in memory mode none. Modified the behavior to
return responses, regardless of the memory mode
* The python.d plugin sometimes does not receive SIGTERM when
netdata exits, resulting in zombie processes. Added a heartbeat
so that the process can exit on SIGPIPE.
* The new SMS Server Tools notifications did not handle errors
well, resulting in cryptic error messages.
Improved error handling.
* Fix segmentation fault in streaming, when two dimensions had
similar names.
* Kubernetes Helm Chart: Fixed incorrect use of namespaces in
ServiceAccount and ClusterRoleBinding RBAC fixes.
* Elastic search: The option to enable HTTPS was not included in
the config file, giving the erroneous impression that HTTPS was
not supported. The option was added.
* RocketChat notifications were not being sent properly.
Added default recipients for roles in the health alarm
notification configuration.
Improvements:
* go.d.plugin v0.4.0 : Docker Hub and k8s coredns collectors,
springboot2 URI filters support.
* go.d.plugin v0.3.1 : Add default job to run k8s_kubelet.conf,
k8s_kubeproxy, activemq modules
* go.d.plugin v0.3.0 : Docker engine, kubelet and kub-proxy
collectors. x509check module reading certs from file support
* Added unified cgroup support that includes v2 cgroups
* Disk stats: Added preferred disk id pattern, so that users can
see the id they prefer, when multiple ids appear for the same
device
* NVIDIA SMI: Added memory free and per process memory usage
charts to the collector
* OpenLDAP: Added TLS support, to allow monitoring of LDAPS.
* PHP-FPM: Add health check to raise alarms when the phpfm server
is unreachable
* PostgreSQL: Our configuration options to connect to a DB did
not support all possible option. Added option to connect to a
PostreSQL instance by defining a connection string (URI).
* python.d.plugin: There was no way to delete obsolete dimensions
in charts created by the python.d plugin. The plugin can now
delete dimension at runtime.
* netdata supports sending its logs to Syslog, but the facility
was hard-coded. We now support configurable Syslog facilities
in netdata.conf.
* Kubernetes Helm Chart improvements:
+ Added serviceName in statefulset spec to align with the k8s
documentation
+ Added preStart command to persist slave machine GUIDs,
so that pod deletion/addition during upgrades doesn't lose
the slave history.
+ Disabled non-essential master netdata collector plugins to
avoid duplicate data
+ Added preStop command to wait for netdata to exit gracefully
before removing the container
+ Extended configuration file support to provide more control
from the helm command line
+ Added option to disable Role-based access control
+ Added liveness and readiness probes.

orchestrator written in Go)
* 7 new data collectors and 11 rewrites of existing data
collectors for improved performance
* A new management API for all netdata servers
* Bind different functions of the netdata APIs to different ports
Management API:
Netdata now has a management API. We plan to provide a full set
of configuration commands using this API.
In this release, the management API supports disabling or
silencing alarms during maintenance periods.
For more information about the management API, check
https://docs.netdata.cloud/web/api/health/#health-management-api
Anonymous statistics:
Anonymous usage information can be collected and sent to Google
Analytics. This functionality is disabled by default in openSUSE.
Remove /etc/netdata/.opt-out-from-anonymous-statistics to enable.
The statistics calculated from this information will be used for:
1. Quality assurance, to help us understand if netdata behaves as
expected and help us identify repeating issues for certain
distributions or environment.
2. Usage statistics, to help us focus on the parts of netdata
that are used the most, or help us identify the extend our
development decisions influence the community.
Information is sent to Netdata via two different channels:
* Google Tag Manager is used when an agent's dashboard is
accessed.
* The script anonymous-statistics.sh is executed by the Netdata
daemon, when Netdata starts, stops cleanly, or fails.
Both methods are controlled via the same opt-out mechanism.
For more information, check
https://docs.netdata.cloud/docs/anonymous-statistics/
Data collection:
This release introduces a new Go plugin orchestrator.
This plugin has its own github repo
(https://github.com/netdata/go-orchestrator). It is open-source,
using the same license and we welcome contributions.
The orchestrator can also be used to build custom data collection
plugins written in Go. We have used the orchestrator to write
many new Go plugins in our go.d plugin github repo.
For more information, check
https://github.com/netdata/go-orchestrator#go-orchestrator-wip
New data collectors:
* Activemq (Go)
* Consul (Go)
* Lighttpd2 (Go)
* Solr (Go)
* Springboot2 (Go)
* mdstat - nonredundant arrays (C)
* CUPS printing system (C)
High performance versions of older data collectors:
* apache (Go)
* dns_query (Go)
* Freeradius (Go)
* Httpcheck (Go)
* Lighttpd (Go)
* Portcheck (Go)
* Nginx (Go)
* cpufreq (C)
* cpuidle (C)
* mdstat (C)

Other improved data collectors:
* Fix the python plugin clock (collectors falling behind).
* adaptec_raid: add to python.d.conf.
* apcupsd: Detect if UPS is online.
* apps: Fix process statistics collection for FreeBSD.
* apps: Properly lookup docker container name when running in ECS
* fail2ban: Add 'Restore Ban' action.
* go_expavar: Don't check for duplicate expvars.
* hddtemp: Don't use disk model as dim name.
* megacli: add to python.d.conf.
* nvidia_smi: handle N/A values.
* postgres: Fix integer out of range error on Postgres 11,
fix locks count.
* proc: Don't show zero charts for ZFS filesystem.
* proc; Fix cached memory calculation.

Health Monitoring:
* Add Prowl notifications for iOS users.
* Show count of active alarms per state in email notifications.
* Show evaluated expression and expression variable values in
email notifications.
* Improve support for slack recipients (channels/users).
* Custom notifications: Fix bug with alarm role recipients.
Dashboards:
* Server filtering in my-netdata menu when signed in to
netdata.cloud
* All units are now IEC-compliant abbreviations (KiB, MiB etc.).
* GUI: Make entire row clickable in the registry menu showing
the list of servers.
Backends:
* Do not report stale metrics to prometheus.
Other:
* Treat DT_UNKNOWN files as regular files.
* API: Stricter rules for URL separators.
- Update to v1.11.1
Improved internal database:
Overflown incremental values (counters) do not show a zero point
at the charts. Netdata detects the width (8bit, 16bit, 32bit,
64bit) of each counter and properly calculates the delta when
the counter overflows.
The internal database format has been extended to support values
above 64bit.
New data collection plugins:
* openldap, to collect performance statistics from OpenLDAP
servers.
* tor, to collect traffic statistics from Tor.
* nvidia_smi to monitor NVIDIA GPUs.
Improved data collection plugins:
* BUG FIX: network interface names with colon (:) in them were
incorrectly parsed and resulted in faulty data collection
values.
* BUG FIX: smartd_log has been refactored, has better python v2
compatibility, and now supports SCSI smart attributes
* cpufreq has been re-written in C - since this module if common,
we decided to convert to an internal plugin to lower the
pressure on the python ones. There are a few more that will be
transitioned to C in the next release.
* BUG FIX: sensors got some compatibility fixes and improved
handling for lm-sensors errors.
Health monitoring:
* BUG FIX: max network interface speed data collection was
faulty, which resulted in false-positive alarms on systems with
multiple interfaces using different speeds (the speed of the
first network interface was used for all network interfaces).
Now the interface speed is shown as a badge.
* alerta.io notifications got a few improvements
* BUG FIX: conntrack_max alarm has been restored (was not working
due to an invalid variable name referenced)
Registry (my-netdata menu):
* It has been refactored a bit to reveal the URLs known for each
node and now it supports deleting individual URLs.
- Update to 1.11.0
* Stock config files are now in /usr/lib/netdata; use the
/etc/netdata/edit-config script to copy and edit them.
* The query engine of netdata has been re-written to support
query plugins. We have already added the following algorithms
that are available for alarm, charts and badges:
+ stddev, for calculating the standard deviation on any
time-frame.
+ ses or ema or ewma, for calculating the exponential weighted
moving average, or single/simple exponential smoothing on
any time-frame.
+ des, for calculating the double exponential smoothing on any
time-frame.
+ cv or rsd, for calculating the coefficient of variation for
any time-frame.
Fixed security issues:
* CVE-2018-18836 Fixed JSON Header Injection (an attacker could
send \n encoded in the request to inject a JSON fragment into
the response).
* CVE-2018-18837 Fixed HTTP Header Injection (an attacker could
send \n encoded in the request to inject an HTTP header into
the response).
* CVE-2018-18838 Fixed LOG Injection (an attacker could send \n
encoded in the request to inject a log line at access.log).
* CVE-2018-18839 Not fixed Full Path Disclosure, since these are
intended (netdata reports the absolute filename of web files,
alarm config files and alarm handlers).
* Fixed Privilege Escalation by manipulating apps.plugin or
cgroup-network error handling.
* Fixed LOG injection (by sending URLs with \n in them).
New data collection modules:
* rethinkdbs for monitoring RethinkDB performance
* proxysql for monitoring ProxySQL performance
* litespeed for monitoring LiteSpeed web server performance.
* uwsgi for monitoring uWSGI performance
* unbound for monitoring the performance of Unbound DNS servers.
* powerdns for monitoring the performance of PowerDNS servers.
* dockerd for monitoring the health of dockerd
* puppet for monitoring Puppet Server and Puppet DB.
* logind for monitoring the number of active users.
* adaptec_raid and megacli for monitoring the relevant raid
controller
* spigotmc for monitoring minecraft server statistics
* boinc for monitoring Berkeley Open Infrastructure Network
Computing clients.
* w1sensor for monitoring multiple 1-Wire temperature sensors.
* monit for collecting process, host, filesystem, etc checks
from monit.
* linux_power_supplies for monitoring Linux Power Supplies
attributes
Data collection orchestrators changes:
* node.d.plugin does not use the js command any more.
* python.d.plugin now uses monotonic clocks. There was a
discrepancy in clocks used in netdata that resulted in a shift
in time of python module after some time (it was missing 1 sec
per day).
* added MySQLService for quickly adding plugins using mysql
queries.
* URLService now supports self-signed certificates and supports
custom client certificates.
* all python.d.plugin modules that require sudo to collect
metrics, are now disabled by default, to avoid security alarms
on installations that do not need them.
Improved data collection modules:
* apps.plugin now detects changes in process file descriptors,
also fixed a couple of memory leaks. Its default configuration
has been enriched significantly, especially for IoT.
* freeipmi.plugin now supports option ignore-status to ignore
the status reported by given sensors.
* statsd.plugin (for collecting custom APM metrics)
+ The charting thread has been optimized for lowering its CPU
consumption when several millions of metrics are collected.
+ sets now report zeros instead of gaps when no data are
collected
+ histograms and timers have been optimized for lowering their
CPU consumption to support several thousands of such metrics
are collected.
+ histograms had wrong sampling rate calculations.
+ gauges now ignore sampling rate when no sign is included in
the value.
+ the minimum sampling rate supported is now 0.001.
+ netdata statsd is now drop-in replacement for datadog statsd
(although statsd tags are currently ignored by netdata).
* proc.plugin (Linux, system monitoring)
+ Unused interrupts and softirqs are not used in charts
(this saves quite some processing power and memory on systems
with dozens of CPU cores).
+ fixed /proc/net/snmp parsing of IcmpMsg lines that failed on
a few systems.
+ Veritas Volume Manager disks are now recognized and named
accordingly.
+ Now netdata collects TcpExtTCPReqQFullDrop and re-organizes
metrics in charts to properly monitor the TCP SYN queue and
the TCP Accept queue of the kernel.
+ Many charts that were previously reported as IPv4, were
actually reflecting metrics for both IPv4 and IPv6.
They have been renamed to ip.*.
+ netdata now monitors SCTP.
+ Fixed BTRFS over BCACHE sector size detection.
+ BCACHE data collection is now faster.
+ /proc/interrupts and /proc/softirqs parsing fixes.
* diskspace.plugin (Linux, disk space usage monitoring)
+ It does not stat() excluded mount points any more (it was
interfering with kerberos authenticated mount points).
+ several filesystems are now by default excluded from
disk-space monitoring, to avoid breaking suspend on
workstations.
* python.d.plugin PYTHON modules (applications monitoring)
+ web_log module now supports virtual hosts, reports http/https
metrics, support squid logs
+ nginx_plus module now handles non-continuous peer IDs
+ ipfs module is optimized, the use of its Pin API is now
disabled by default and can enabled with a netdata module
option (using the IPFS Pin API increases the load on the
IPFS server).
+ fail2ban module now supports IPv6 too.
+ ceph module now checks permissions and properly reports
issues
+ elasticsearch module got better error handling
+ nginx_plus module now uses upstream ip:port instead of
transient id to identify dimensions.
+ redis, now it supports Pika, collects evited keys, fixes
authentication issues reported and improves exception
handling.
+ beanstalk, bug fix for yaml config loading.
+ mysql, the % of active connections is now monitored,
query types are also charted.
+ varnish, now it supports versions above 5.0.0
+ couchdb
+ phpfpm, now supports IPv6 too.
+ apache, now supports IPv6 too.
+ icecast
+ mongodb, added support for connect URIs
+ postgress
+ elasticsearch, now it supports versions above 6.3.0,
fixed JSON parse errors
+ mdstat , now collects mismatch_cnt
+ openvpn_log
* node.d.plugin NODE.JS modules
+ snmp was incorrectly parsing a new OID names as float.
* charts.d.plugin BASH modules
+ nut now supports naming UPSes.
Health monitoring:
* Added variable $system.cpu.processors.
* Added alarms for detecting abnormally high load average.
* TCP SYN and TCP accept queue alarms, replacing the old softnet
dropped alarm that was too generic and reported many false
positives.
* system alarms are now enabled on FreeBSD.
* netdata now reads NIC speed and sets alarms on each interface
to detect congestion.
* Network alarms are now relaxed to avoid false positives.
* New bcache alarms.
* New mdstat alarms.
* New apcupsd alarms.
* New mysql alarms.
* New notification methods:
+ rocket.chat
+ Microsoft Teams
+ syslog
+ fleep.io
+ Amazon SNS
Backends:
* Host tags are now sent to Graphite
* Host variables are now sent to Prometheus
Streaming:
* Each netdata slave and proxy now filter the charts that are
streamed. This allows exposing netdata masters to third parties
by limiting the number of charts available at the master.
* Fixed a bug in streaming slaves that randomly prevented them
to resume streaming after network errors.
* Fixed a bug that on slaves that sent duplicated chart names
under certain conditions.
* Fixed a bug that caused slaves to consume 100% CPU (due to a
misplaced lock) when multiple threads were adding dimensions
on the same chart.
* The receiving nodes of streaming (netdata masters and proxies)
can now rate-limit the rate of inbound streaming requests
received.
* Re-worked time synchronization between netdata slaves and
masters.
API:
* Badges that report time, now show "undefined" instead of
"never".
Dashboard:
* Added UTC timezone to the list of available time-zones.
* The dashboard was sending some non-HTTP compliant characters
at the URLs that made netdata dashboards break when used under
certain proxies.
-------------------------------------------------------------------
Tue Mar 27 20:06:12 UTC 2018 - 9+suse@cirno.systems
- Remove _service
- Add GPG signature
- Use %license macro
- Update to v1.10.0
* new plugins:
- BTRFS - monitor the allocations of BTRFS filesystems (netdata can now
properly detect when btrfs is going out of space)
- BCACHE - monitor the caching block layer that allows building hybrid
disks using normal HDDs and SSDs
- Ceph - monitor ceph distributed storage
- nginx plus - monitor the nginx+ web servers
- libreswan - monitor IPSEC tunnels
- Traefik - monitor traefik reverse proxies
- icecast - monitor icecast streaming servers
- ntpd - monitor NTP servers
- httpcheck - monitor any remote web server
- portcheck - monitor any remote TCP port
- spring-boot - monitor java spring boot applications
- dnsdist - monitor dnsdist name servers
- hugepages - monitor the allocation of Linux hugepages
* enhanced/improved plugins:
- statsd
+ statsd dimensions now support the options the external plugin
dimensions support (currently the only usable option is hidden to add
the dimension, but make it hidden on the dashboard - a hidden
dimension can participate in various calculations, including alarms).
+ statsd now reports the CPU usage of its threads at the netdata
section.
+ statsd metrics are logged to access.log the first time they are
encountered.
+ statsd metrics now accept the special value zinit to allow them get
initialized without altering their values (this is useful if you have
rare metrics that you need to initialize when netdata starts).
+ statsd over TCP is now a lot faster - netdata can process up to 3.5mil
statsd metrics / second using just one core. Added options to control
the timeouts of TCP statsd connections.
+ fixed the title and context of statsd private charts
+ statsd private charts can now be hidden from the dashboard
- web_log
+ Added web server response timings histogram
- containers monitoring
+ netdata now monitors systemd-nspawn containers.
+ netdata now renames charts of kubernetes containers.
+ virsh is now called with -r to avoid prompting for password
+ cgroup-network is now a lot more strict, preventing unauthorized
privilege escalation
+ cgroup-network now searches for container processes in sub-cgroups
too - this improves the mapping of network interfaces to containers
+ cgroup-network now works even when there are no veth interfaces
in the system
- system memory
+ treat slab memory as cached
+ added a new chart for monitoring the memory available for use,
before hitting swap
+ netdata now monitors Linux hugepages and (transparent) hugepages
- diskspace
+ support huge amounts of mountpoints - netdata was crashing with stack
overflow due to recursion - now it is a loop, so any number of mount
points is supported
- network interfaces
+ moved tcp passive and active opens to a separate chart, to allow the
TCP issues dimensions scale better by default
+ updated the information presented on TCP charts to match the latest
v4.15 kernel source
- postgres
+ new charts:
checkpointer
bgwriter
autovacuum
replication delta
WAL archive
WAL
temporary files
+ The postgres plugin now also works when postgres is in recovery mode.
- rabbitmq
+ added Erlang run queue chart. This is useful in conjunction with the
existing Erlang processes chart to get a better overall idea of what's
going on in the Erlang VM.
+ added rabbitmq information on the dashboard to complement the charts.
- apps.plugin
netdata prior to this version was detecting the user and group of
processes by examining the ownership of /proc/PID/stat. Unfortunately it
seems that the owneship of files in /proc do not change when the process
switches user. So, netdata could not detect the user and group of
processes that started as root and then switched to another user.
Now netdata reads /proc/PID/status:
+ process ownship information is now accurate
+ eliminated the need to read /proc/PID/statm (all the information of
/proc/PID/statm is available in /proc/PID/status)
+ allowed netdata to read VmSwap, so a new chart has been added to
monitor the swap memory usage per process, user and group.
+ The new plugin is 20% more expensive in terms of CPU. We tried hard
to optimize it, but this is as good as it can get.
- haproxy
+ hrsp_1xx, hrsp_2xx, hrsp_3xx, hrsp_4xx, hrsp_5xx, hrsp_other,
hrsp_total for backands and frontends
+ qtime, ctime, rtime, ttime metrics for backend servers
+ backend servers In UP state
- uptime
+ netdata now uses /proc/uptime when CLOCK_BOOTTIME does not report the
same uptime. In containers CLOCK_BOOTTIME reports the uptime of the
host, while /proc/uptime reports the uptime of the container, so now
netdata correctly reports the uptime of the container.
- ksm
+ removed to_scan dimension
+ the savings % reported by netdata was less than the actual - fixed it.
- mdstat
+ various fixes to better monitor rebuild time and rate
- elasticsearch
+ Added several charts for translog / indices segments statistics and
JVM buffer pool utilization, which are often helpful when evaluating
an elasticsearch node health
- apcupsd
+ netdata now supports monitoring multiple APC UPSes.
- isc-dhcpd
+ netdata now also supports monitoring IPv6 leases
- fronius
+ added a new dimension solar_consumption
+ added alarms
- stiebeleltron
+ added alarms
- python.d
+ python.d.plugin can now start even if /etc/netdata/python.d.conf
is missing
+ python.d.plugin now has an internal run counter
+ the unicode decoding of the plugin has been fixed
+ the plugin now does not validate self-signed certificates
+ the plugin can not revive obsolete charts
- charts.d
+ charts.d.plugin BASH modules can now have custom number of retries in
case of data collection failures
* new alarm notifications plugins:
- alerta
- IRC
* web server:
- netdata now has a new internal web server that supports a fixed number
of threads - we call it static web server. This web server allows
netdata to work around memory fragmentation (since the treads are fixed,
the underlying memory allocators reuse the same memory arenas) and cpu
utilization (we can control the number of threads that will be used by
netdata). This is the default now.
- now the static threads web server reports the CPU usage of each of its
threads.
- the HTTP response headers now include the netdata version
* dashboard:
- the print button now respects the URL path netdata is hosted.
- dygraphs updated to the latest version - this fixes an issue that
prevented netdata charts from being interactive under certain conditions
- added dygraph theme logscale
- fontawesome updated to version 5
- d3 updated to the latest version (this broke c3 charts that require an
older version)
- added d3pie charts
- custom dashboards can now have alarms for specific roles (all, none,
one or more).
- allow stacked charts to zoom vertically when dimensions are selected
- netdata now has a global XSS protection
- netdata now uses intersectionObserver when available - this improves the
scrolling performance of the dashboard.
- prevent date, time and units from wrapping at the charts legends
- various units scaling improvements
- added data-common-colors="NAME" chart option for custom dashboards
- added wiki page for creating custom dashboards on Atlassian's Confluence
- prevented a double click on the charts' toolbox to select the text of
the buttons.
- fixed the alignment of dashboard icons
- added a simple js, called refresh-badges.js, to update badges on a
custom web page
* badges:
- netdata badges can now be scaled
* API:
- added gtime parameter, for group time. This is used to request from
netdata to return values in a different rate (i.e. gtime=60 on a X/sec
dimension, will return X/min).
- fixed a rounding bug in JSON generation
- the dimensions= parameter now supports simple patterns and added option
values match-ids and match-names to control which matches are executed
for dimensions.
* alarms:
- "system.swap" alarms now send notifications with a 30 seconds delay,
to work-around a kernel bug that incorrectly reports all swap as
instantly used under containers
- added alarm to predict the time a mount point will run out of inodes
- added alerta.io notifications
- added available memory alarm
- removed unsupported html tags from hipchat notifications.
- pagerduty notifications have been modified to avoid incident duplication
- alarm definitions can now use both chart IDs and chart names (prior to
this version only chart IDs were allowed).
- curl options (eg for disabling SSL certificates verification) for
alarm-notify.sh can now be defined in health_alarm_notify.conf.
- netdata can now send notifications to IRC channels
* backends:
- on netdata masters, allow filtering the hosts that will be sent to
backends with send hosts matching = * pattern.
- improved connection error handling and added retries to allow netdata
connect to certain backends that failed with EALREADY or EINPROGRESS.
- json backends now receive host tags (the tags have to be formatted in a
json friendly way)
- re-worked the alarm that triggers when backend data are lost,
to avoid flip-flops.
- prometheus backends:
+ added URL option timestamps=yes|no to /api/v1/allmetrics to support
prometheus Pushgateway
+ added netdata_info variable with the version of netdata
+ renamed netdata_host_tags to netdata_host_tags_info (the old exists
but is deprecated and will be removed eventually)
+ when prometheus uses average metrics, netdata remembers the last
access time the prometheus collected metrics, on a per host basis.
* metrics streaming between netdata:
- netdata masters and proxies now expose the version of the netdata
collecting the metrics, not their own. So, now a netdata master shows
on the dashboard and sends to backends the version of the netdata
collecting the metrics
- added stream.conf option multiple "connections = accept | deny" to allow
or deny multiple connection for the same netdata host. The default
remains "accept", but it is likely to be changed to no on future
versions.
* other:
- added global option gap when lost iterations to control the number of
iterations that should be lost to show a gap on the charts.
- various fixes/improvements related to netdata logs - the main change is
that now netdata logs the thread name that logged the message, providing
helpful insights about the thread that complained.
- re-worked the exit procedure of netdata to allow it cleanup properly -
sometimes netdata was deadlocked during exit, waiting forever - now
netdata always exits promptly
- fixed compilation on ancient gcc versions
- netdata was always setting itself to the idle process scheduling
priority, even when it was configured to do otherwise. Fixed it.
-------------------------------------------------------------------
Sun Dec 17 22:47:20 UTC 2017 - 9@cirno.systems
- Update to v1.9.0
* new features:
- IP address ACLs
- auto-scaling units (KB → MB → GB → TB etc.)
- dashboard snapshots for any timeframe/resolution
- detection of TCP overflows and dropped connections
- detection of redis background save failures
- export dashboards to PDF
- flock.com and kavenegar.com alarm notifications
- highlighting timeframes on all charts by holding Ctrl or Alt
- monitoring of couchdb, powerdns, beanstalkd and dnsdist
- monitoring of libvirt VMs
- new alarms:
1. too many tcp orphan sockets
2. tcp memory that detects that the tcp stack is under memory pressure
or close to giving memory errors
3. too many tcp connections (for kernels that do not support dynamic
allocation of connections)
- timezone support
- unit conversion (temperatures, time, etc.)
* fixes/improvements:
- better/faster dashboard scrolling
- python.d.plugin rewritten
+ supports option autodetection_retry: SECONDS
+ the new URL service disables certificates checks by default,
to allow self-signed certificates to work without configuration.
- streaming:
+ netdata proxies with more than 100 slaves had a timing issue that
caused them to crash randomly on slave reconnects. Parts of the code
have been rewritten to get rid of the timing issue.
+ netdata slaves and proxies now have a protection that ensures they will
never use 100% CPU, even if the master is misbehaving.
+ expired orphaned hosts are now removed from the my-netdata menu of the
dashboard.
+ streaming functions can now be monitored via access.log
+ streaming now transfers alarm variables too
- web_log plugin
+ custom regex now supports parsing hostnames and IPs
+ now parses lines with error 408 (request timeout - these are a special
case, since the request has not received by the web server, so the log
line is incomplete)
+ now properly parses resp_length with value
- disks under Linux are renamed using /dev/disk/by-label. An option has been
added at netdata.conf to also allow renaming based on /dev/disk/by-id.
- chrony is now disabled by default, because there have been reports that
chronyc enters an infinite loop in CentOS and RHEL.
- tomcat improvements to support flavors of the tomcat server
- chart system.io (the total system Disk I/O) is now calculated by
aggregating the reads and writes of all physical disks. The previous
system.io chart (that is based on pgpgin and pgpgout from /proc/vmstat)
is now named system.pgpgio. The key difference is that the new system.io
now sees ZFS I/O, and it also correctly and accurately sums the real disk
bandwidth of RAID arrays.
- chart system.net (the total system network bandwidth) is now calculated
by aggregating the bandwidth of all physical network interfaces and is
common for both IPv4 and IPv6.
- tc (QoS) charts now sort the dimensions on the legends, the same way tc
reports them.
- mysql (and mariadb) got new charts for galera replication
- postgres versions <= 10 the WAL directory was named pg_xlog' and from 10
upwards has been renamed to pg_wal
- freeipmi.plugin got a command line option (can be given in netdata.conf)
to ignore certain sensor IDs that are faulty.
- minor openvpn_log, smartd, smartd_log, varnish, mdstat, dns_query_time,
isc_dhcpd, freeradius and node.d.plugin fixes/improvements
- netdata now supports multiple plugin directories. The setting is the same
in netdata.conf, plugins directory = "DIRECTORY1" "DIRECTORY2" ...,
up to 20 directories.
- netdata now supports alarms variables. Each plugin can now define host
global and chart local variables with static values that can be used in
alarms' expressions.
- dashboard:
+ hover selection of charts is now faster on all browsers
+ the dashboard is now fixed when a modal is open, preventing scrolling
+ the dashboard now uses fontawesome 5.0.1 for icons
+ chart names can now be searched with browser control-F
+ netdata now detects libvirt VM network interfaces and moves them to the
VM section of the dashboard
+ now shows the context, resolution and plugin/module of each chart in
tooltips
+ should now put a lot less CPU pressure on the browser when the page
does not have focus
- statsd:
+ metrics can now be added to statsd synthetic charts using patterns
+ dimensions added to statsd synthetic charts can automatically be renamed
using a dictionary
+ timers and histograms now report zeros when nothing is collected
- badges:
+ fixed a bug in netdata badges that was incorrectly matching zero values
with the null color condition
+ added API option display_absolute to allow badges use the signed value
for color evaluation, but present the absolute value
- alarms/notifications:
+ warning emails sent by netdata are now a little bit more orange
(they were a bit greenish)
+ fixed a bug in email notifications that was triggering a corrupted MIME
match by anti-spam solutions
+ pushbullet notifications now track the devices, so that per-device
filtering at pushbullet is possible. Also improved the formatting a bit.
+ correct priority of warnings for pushover notifications
+ alarms can now use variables like this:
${variable with spaces or +, -, *, / in it}
- other:
+ access.log has been refactored to support monitoring all netdata
operations
+ inodes monitoring is now by default disabled for mount points based on
filesystems that do not have a maximum inode threshold (such as cephfs)
+ rabbitmq has been added to apps_groups.conf so that apps.plugin now
monitors (cpu, memory, disk I/O, sockets, etc) rabbitmq instances
+ several email and log management apps have been added to email and logs
targets of apps_groups.conf
+ ceph target added to apps_groups.conf to allow netdata to monitor Ceph
