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:
Alert if the number of Redis Enterprise Cluster connections falls out of range.
Alert if Redis Enterprise Cluster Latency exceeds the threshold.
Alert if the number of Redis Enterprise database connections falls out of range.
Alert if Redis Enterprise database latency exceeds the threshold.
Alert if the number of Redis Enterprise node connections falls out of range.
Alert if Redis Enterprise node latency exceeds the threshold.
Periodic backup has been delayed for longer than specified threshold value (minutes)
CRDB source sync lag is higher than specified threshold value (seconds)
CRDB source sync had a connection error while trying to connect to replica source
CRDB sync encountered in general error
Latency is higher than specified threshold value (microsec)
Replica of sync lag is higher than specified threshold value (seconds) (deprecated)
Throughput is higher than specified threshold value (requests / sec)
An alert for state machines that are running for too long
Throughput is lower than specified threshold value (requests / sec)
Dataset RAM overhead of a shard has reached the threshold value (% of its RAM limit)
Percent of values kept in a shard’s RAM is lower than (% of its key count)
Replica of source sync lag is higher than specified threshold value (seconds)
Replica of source sync has connection error while trying to connect replica source
Replica of sync encountered in general error
Number of values kept in a shard’s RAM is lower than (values)
Dataset size has reached the threshold value (% of the memory limit)
Replica of sync has connection error while trying to connect replica source (deprecated)
Replica of sync encountered in general error (deprecated)
Cluster certificate expiration in day(s)
True high availability requires an odd number of nodes with a minimum of three nodes
Flash memory committed to databases is larger than cluster total flash memory
Not all databases are running the same open source version
Not all nodes in the cluster are running the same Redis Enterprise Cluster version
Issues with internal cluster databases
Multiple cluster nodes are down - this might cause data loss
Cluster capacity is less than total memory allocated to its databases
Database replication requires at least two nodes in cluster
AOF reaching disk I/O limits
Some node checks have failed
Node CPU utilization has reached the threshold value (% of the utilization limit)
Node ephemeral storage has reached the threshold value (% of the storage limit)
Node failed
Node flash storage has reached the threshold value (% of the storage limit)
Insufficient AOF disk space
Internal certificate on node will expire in x days
Node memory has reached the threshold value (% of the memory limit)
Node network throughput has reached the threshold value (bytes/s)
Node persistent storage has reached the threshold value (% of the storage limit)
