Ambari uses Grafana to display metrics. I am using external data source to view other metrics. I want to upgrade grafana version from 2.6 to 4.0-beta for alerting feature. Should I
upgrade grafana provided inside the HDP 2.5 package
or
install new version separately?
How to do this and which method is recommended?
I would definitely go with installing a separate version. You can get a Grafana 3.x compatible plugin from here - https://grafana.net/plugins/praj-ams-datasource and then configure your datasource to use the HDP Cluster.
I am working on a v4.x compatible version and should have it done very soon as well.
