# Changelog
## 1.0
* Remove the old API: `NewConnWith`, `WithPrefix` and etc and move to a simple `New` function.
* Prefix is no longer supported in this package.
* Change the Hook structure to have only two members: `logrus.Formatter` and `io.Writer`.
## 0.4
* Update the name of the package from `logrus_logstash` to `logrustash`

@ -41,61 +46,8 @@ This is how it will look like:
"type" => "myappName"
}
```
## Hook Fields
Fields can be added to the hook, which will always be in the log context.
This can be done when creating the hook:
```go
hook, err := logrustash.NewHookWithFields("tcp", "172.17.0.2:9999", "myappName", logrus.Fields{
"hostname": os.Hostname(),
"serviceName": "myServiceName",
})
```
Or afterwards:
```go
hook.WithFields(logrus.Fields{
"hostname": os.Hostname(),
"serviceName": "myServiceName",
})
```
This allows you to set up the hook so logging is available immediately, and add important fields as they become available.
Single fields can be added/updated using 'WithField':
```go
hook.WithField("status", "running")
```
## Field prefix
The hook allows you to send logging to logstash and also retain the default std output in text format.
However to keep this console output readable some fields might need to be omitted from the default non-hooked log output.
Each hook can be configured with a prefix used to identify fields which are only to be logged to the logstash connection.
For example if you don't want to see the hostname and serviceName on each log line in the console output you can add a prefix:
```go
hook, err := logrustash.NewHookWithFields("tcp", "172.17.0.2:9999", "myappName", logrus.Fields{
"_hostname": os.Hostname(),
"_serviceName": "myServiceName",
})
...
hook.WithPrefix("_")
```
There are also constructors available which allow you to specify the prefix from the start.
The std-out will not have the '\_hostname' and '\_servicename' fields, and the logstash output will, but the prefix will be dropped from the name.
