Openshift Template for monitoring of Che server

Import this into your Che installation to gain monitoring and visualization capabilities.

All you need to do is to create a route exposing your grafana service. Also make sure that Prometheus is configured to scrape your Che server correctly - look at the prometheus-config config map and make sure that the targets lists the correct hostname of the Che server within your project.

Also make sure that your Che server is configured to expose the metrics. The CHE_METRICS_ENABLED environment variable of the che deployment needs to be set to true.

To access the Grafana dashboard, use the username admin with password admin. Once in Grafana, you will see a preconfigured dashboard called "Che Server" containing some basic stats about the Che installation.
