|

|
||||
- Update to upstream version 0.16.0
|
||||
* Bugfixes:
|
||||
+ Don't throw NPE if .help() wasn't called
|
||||
+ Don't wrap a RuntimeException in another RuntimeException.
|
||||
+ Make pushgateway module compile on Java 11
|
||||
+ Make sure GZIPOutputStream is always closed for httpserver
|
||||
+ Specify the charset of HTTPServer response for systems not
|
||||
using utf-8 by default
|
||||
+ Use <packaging>bundle</packaging> everywhere so that
|
||||
client_java works with OSGI again.
|
||||
+ use the correct name for the metric type gaugehistogram in
|
||||
OpenMetrics (previously this was wrongly named
|
||||
gauge_histogram)
|
||||
+ Correct handling of HEAD requests.
|
||||
+ Apply ServletConfig during Servlet initialization in
|
||||
simpleclient_servlet and simpleclient_servlet_jakarta
|
||||
+ HTTPServer: Don't send a Content-Length header when
|
||||
Transfer-Encoding is chunked.
|
||||
+ simpleclient_log4j set the log4j dependency scope as provided
|
||||
so that users don't accidentally pull the log4j version used
|
||||
in client_java.
|
||||
Note: This module is for monitoring log4j version 1,
|
||||
in simpleclient_log4j2 the dependency is already provided.
|
||||
+ simpleclient_dropwizard set the Dropwizard dependency scope as
|
||||
provided so that users don't accidentally pull the Dropwizard
|
||||
version used in client_java.
|
||||
+ Fix missing Dropwizard metrics in Vertx.
|
||||
+ Fix incorrect buffer size in the Servlet exporter.
|
||||
+ Fix sample name filter for the JMX metric
|
||||
jvm_memory_bytes_committed.
|
||||
* Enhancements:
|
||||
+ Bump caffeine dependency to 2.7.0 to support AsyncCache.
|
||||
+ Added health check api to simpleclient_httpserver.
|
||||
+ Remove dependency on sun.misc.Unsafe, allowing building on
|
||||
JDK11
|
||||
+ Wrap PrintWriter with BufferedWriter, making servlet
|
||||
exposition about 2x faster
|
||||
+ Handle empty label values for the pushgateway
|
||||
+ Add Bill of Materials
|
||||
+ Count HTTP statuses returned for servlet filter
|
||||
+ Introduce TestContainers integration test, for example for
|
||||
testing different Java versions. This means you need Docker
|
||||
installed to run ./mvnw verify.
|
||||
+ HTTPServer: Set request/response timeouts.
|
||||
+ HTTPServer: Make HTTPMetricHandler public so that it can be
|
||||
used in a custom HTTPServer.
|
||||
+ New JVM memory metrics: jvm_memory_pool_collection_used_bytes,
|
||||
jvm_memory_pool_collection_committed_bytes,
|
||||
jvm_memory_pool_collection_max_bytes,
|
||||
jvm_memory_pool_collection_init_bytes,
|
||||
jvm_memory_objects_pending_finalization.
|
||||
+ Version bumps (junit, jetty, maven plugins)
|
||||
+ add support for Jakarta Servlet, implemented in the new
|
||||
simpleclient_servlet_jakarta module.
|
||||
+ provide a way for filtering metrics by name / name prefix.
|
||||
This can be configured either in the HTTPServer, or in the
|
||||
Servlet exporter (both javax and Jakarta). For example, if
|
||||
some JMX metrics cause performance issues, this can be used
|
||||
for excluding these metrics.
|
||||
+ for the Servlet filter (both javax and Jakarta): Add a
|
||||
parameter to strip the deployment path from the path label.
|
||||
+ Add HTTP Authentication to the HTTPServer #682.
|
||||
+ Allow passing a custom registry to the logback
|
||||
InstrumentedAppender.
|
||||
+ Lots of more integration tests and tests with different Java
|
||||
versions.
|
||||
+ Make HTTPMetricHandler public so that users can use them in
|
||||
their own HttpServers.
|
||||
+ Make Base64 encoding in the HTTP authentication for the
|
||||
PushGateway work with all Java versions.
|
||||
+ The HTTPServer can now be configured to use SSL.
|
||||
+ Lots of dependency version bumps.
|
||||
+ Environment variable PROMETHEUS_DISABLE_CREATED_SERIES=true
|
||||
for disabling _created metrics.
|
||||
+ Support for OpenTelemetry trace sampling: Only traces that are
|
||||
sampled will be used as exemplars.
|
||||
+ Handle thread IDs <= 0. Apparently Apache Zookeeper generates
|
||||
negative thread IDs, which causes issues in jmx_exporter.
|
||||
+ Mark opentelemetry-api as optional to make it an optional
|
||||
dependency in OSGi.
|
||||
+ Move servlet adapters to an internal package to avoid
|
||||
duplicating classes when building OSGi bundles.
|
||||
+ Extend the API of the HTTPServer.Builder to allow custom
|
||||
ExecutorService instances.
|
||||
+ Reduce the number of core threads in HTTPServer from 5 to 1.
|
||||
The HTTPServer will still start up to 5 threads on demand if
|
||||
there are parallel requests, but it will use only 1 thread as
|
||||
long as requests are sequential.
|
||||
+ Optimize metric name sanitization: Replace the regular
|
||||
expression with a hard-coded optimized algorithm to improve
|
||||
performance.
|
||||
+ Lots of dependency version bumps.
|
||||
* Changes:
|
||||
+ Switch data model to OpenMetrics. Primarily this means that
|
||||
_total if present is stripped from the metric name of
|
||||
counters, and _total is now always a suffix on the sample
|
||||
value. This means that all Counter samples now have a _total
|
||||
suffix
|
||||
+ The io.prometheus.client.Collector.Type enum's value UNTYPED
|
||||
renamed to UNKNOWN
|
||||
* Features:
|
||||
+ Add Info and Enumeration metric types for direct
|
||||
instrumentation
|
||||
+ Counter, Summary, and Histogram metrics now expose a _created
|
||||
sample with when their child was created
|
||||
+ Add support for units
|
||||
+ Add gauge histograms, info, stateset for custom collectors
|
||||
+ Support negotiating and exposing OpenMetrics for all HTTP
|
||||
server exposition
|
||||
+ Add ability to filter metrics in DropwizardExports
|
||||
+ Exemplars: API for adding OpenMetrics Exemplars and
|
||||
out-of-the-box integration with OpenTelemetry tracing.
|
||||
- Added patch:
|
||||
* remove_opentelemetry_tracer.patch
|
||||
+ remove dependency on opentelemetry
