Monitoring and Metrics
Redis Enterprise Software (RS) includes many useful metrics that can be tracked to give you a detailed picture of what is going on in the cluster/node/database. Below are some of the metrics for RS and Redis on Flash (RoF). Also included is a list of metrics that are important how they are computed from other metrics. For example, if I need the know the RAM hit ratio you can dive the Request served from RAM by the total number of requests.
The RS Nagios plugin enables you to monitor the status of RS related objects and alerts. The RS alerts can be related to the cluster, nodes, or databases. The alerts that can be monitored via Nagios are the same alerts that can be configured in the RS UI in the Settings > Alerts page, or the specific Database > Configuration page. All alert configurations (active / not active, setting thresholds, etc') can only be done through the RS UI, they cannot be configured in Nagios.
From Redis Enterprise Software version 5.0.2 and higher, you can connect your Prometheus or Grafana server to your Redis Enterprise cluster in order to collect and display metrics data. Metrics are exposed at the node, database, shard and proxy levels. Prometheus (https://prometheus.io/) is an open-source systems monitoring and alerting toolkit that can scrape metrics from different sources. Grafana (https://grafana.com/) is an open-source, feature-rich metrics dashboard and graph editor that can process Prometheus data.
