marathon-event-metrics

marathon-event-metrics is a tool for reporting Marathon events to InfluxDB.

Configuration

The tool is configured via the following environment variables:

• INFLUX_HOST (no default value) - InfluxDB host
• INFLUX_PORT (8086) - InfluxDB http API port
• INFLUX_DB (marathon) - name of the database that will hold the measurements. It must already exist. The tool will use the default retention policy.
• INFLUX_STATIC_TAGS (no default value) - a set of static tags to be sent with every data point, formatted according to Influx's line protocol, e. g. environment=dev,foo=bar
• MARATHON_HOST (localhost) - Marathon host
• MARATHON_PORT (8080) - Marathon http API port
• CALLBACK_HOST (localhost) - the host that Marathon should send the events to, aka the host this application is running on
• PORT0 (defaults to the value of APP_PORT) - this application's http API port that is available "publicly" (e. g. when running inside a Docker container)
• APP_PORT (9999) - the "local" http API port
