Working with Rules

The Redis cartridge provides a comprehensive set of preconfigured rules designed to monitor various aspects of Redis server performance and health. You can modify these rules, including changing default threshold values. For more information, refer to Working with Reports.

This section describes the following rules:

Redis Enterprise Cluster Connections

Alert if the number of Redis Enterprise Cluster connections falls out of range.

Redis Enterprise Cluster Latency

Alert if Redis Enterprise Cluster Latency exceeds the threshold.

Redis Enterprise Database Connections

Alert if the number of Redis Enterprise database connections falls out of range.

Redis Enterprise Database Latency

Alert if Redis Enterprise database latency exceeds the threshold.

Redis Enterprise Node Connections

Alert if the number of Redis Enterprise node connections falls out of range.

Redis Enterprise Node Latency

Alert if Redis Enterprise node latency exceeds the threshold.
