Enhancements / Bug Fixes

Redis datasource installation

Unfortunately it is not possible to sign community plugins at the moment. Therefore the PCP Redis datasource plugin needs to be allowed explicitely in the Grafana configuration file:

allow_loading_unsigned_plugins = pcp-redis-datasource

Restart Grafana server, and check the logs if the plugin loaded successfully.

Deprecated features

• redis: Using label_values(metric, label) in a Grafana variable query is deprecated due to performance reasons. label_values(label) is still supported.
