v0.3.0-RC3

I started to realise that work done for #17, produces too much noise on the STDERR logs. I decided to split the metrics we collect into regular and debug. The following table now displays the updated list of metrics displayed normally and some via --debug flag.

Metrics

We collect some metrics internally in marathon-alerts. They're dumped periodically to STDERR. You can find the list of metrics and it's usage in the following table

Metric	Description
alerts-suppressed-cleaned	Number of alerts we cleaned up because they got expired from suppress duration.
notifications-total	Total number of notifications we sent from AlertManager to NotificationManager
notifications-warning	Number of Warning check notifications we sent from AlertManager to NotificationManager
notifications-critical	Number of Critical check notifications we sent from AlertManager to NotificationManager
notifications-resolved	Number of Pass (aka Resolved) check notifications we sent from AlertManager to NotificationManager

Debug Metrics

Apart from the standard metrics above, we also collect quite a few other metrics, mostly for debugging purposes. You can enable these metrics if run marathon-alerts with a --debug flag.

Metric	Description
alerts-suppressed-called	Number of times we called AlertManager.cleanUpSupressedAlerts()
alerts-process-check-called	Number of times we called AlertManager.processCheck()
alerts-manager-stopped	Number of times we called AlertManager.Stop()
apps-checker-stopped	Number of times we called AppChecker.Stop()
apps-checker-marathon-all-apps-api	Number of times we called Marathon's /v2/apps API
apps-checker-marathon-app-api	Number of times we called Marathon's /v2/apps/<id> API
apps-checker-alerts-sent	Number of checks we sent to AlertManager from AppChecker
apps-checker-check-<name>	Number of checks identified by <name> we sent to AlertManager
apps-checker-app-<id>	Number of checks for an app identified by <id> we sent to AlertManager
apps-checker-<id>-<name>	Number of checks identified by <name> for an app identified by <id> we sent to AlertManager
