log4js-logstash
===============
[](http://travis-ci.org/gembly/log4js-logstash)
This is a very simple log4js appender that can talk to logstash instances. This version is still very specific to Gembly Games B.V. but feel free to fork and adjust =)
Installation
------------
You can install install log4js-logstash by adding this .git url to your package.json
Usage: logstash configuration
-----------------------------
In the "input" part of the logstash server conf :
input {
tcp {
codec => "json"
data_timeout => 10
port => 5959
type => "tcp-input"
}
}
Usage: log4js configuration
---------------------------
Plain javascript
```javascript
var log4js = require('log4js');
log4js.configure({
"appenders": [
{
"category": "TEST",
"type": "log4js-logstash",
"host": "localhost",
"port": 5959,
"fields": {
"instance": "MyAwsInstance",
"source": "myApp",
"environment": "development"
}
},
{
"category": "tests",
"type": "console"
}
],
"levels": {
"tests": "DEBUG"
}
});
var log = log4js.getLogger('tests');
log.error('hello hello');
```
Or in YAML
```yaml
appenders:
