graylog2-plugin-alarmcallback-exec

THIS CODE IS UNMAINTAINED

WARNING: This code works on Graylog 0.10, not on 0.20 or any later version.

Please see biz.dfch.j.graylog2.plugin.alarm.execscript for an up to date version that works -- as of this writing -- with Graylog 1.0.

See graylog2-plugin-alarmcallback-exec github issue #4.

Your old exec scripts won't work with the the dfch version, but you should be able to quickly get something started with something like this:

runCommand('/path/to/some-script.py',
           {env: {GL2_STREAM: (''+stream.getTitle()),
                  GL2_DESCRIPTION: (''+result.getResultDescription())}})

Readme

A graylog-server plugin that executes a command. The command is configurable in the graylog plugin system settings.

The alarm topic and description are passed to the process environment.

Variable name Contents
GL2_TOPIC The alarm topic
GL2_DESCRIPTION The alarm description

Examples

Python example script that retrieves the stream id from the mongo database using the alarm topic and queries elasticsearch for the last log messages on that stream. The log messages are sent to the email addresses specified on the command line. Plugin configuration: graylog-email-alert.py alert@example.com more@example.com

Prebuilt Download

For your convenience a prebuilt jar is available for download which can be placed in the /plugin/alarm_callbacks/ directory of your graylog2 server.

There have been reports that you need to remove the "-2" from the filename before graylog2 detects it.
