13.4.5. Metrics Action Hooks

With the release of OpenShift Enterprise 2.1, you can now use metrics action hook to collect metrics at a gear level. Create a new file named metrics in the App_Name/.openshift/action_hooks directory to use the metrics action hook.

You can provide an application with a metrics action hook if the Watchman metrics plug-in is enabled by the system administrator. The application metrics action hook is invoked at an interval configured for the Watchman plug-in. Ensure the action hook is an executable file and that the action hook writes to standard out (STDOUT).
