Cluster metrics

Documents the cluster metrics used with Redis Enterprise Software REST API calls.

Metric name Type Description
available_flash float Sum of available flash in all nodes (bytes)
available_memory float Sum of available memory in all nodes (bytes)
avg_latency float Average latency of requests handled by all cluster endpoints (micro-sec); returned only when there is traffic
bigstore_free float Sum of free space of backend flash (used by flash DB's BigRedis) on all cluster nodes (bytes); only returned when BigRedis is enabled
bigstore_iops float Rate of I/O operations against backend flash for all shards which are part of a flash-based DB (BigRedis) in the cluster (ops/sec); returned only when BigRedis is enabled
bigstore_kv_ops float Rate of value read/write operations against back-end flash for all shards which are part of a flash based DB (BigRedis) in cluster (ops/sec); only returned when BigRedis is enabled
bigstore_throughput float Throughput I/O operations against backend flash for all shards which are part of a flash-based DB (BigRedis) in the cluster (bytes/sec); only returned when BigRedis is enabled
conns float Total number of clients connected to all cluster endpoints
cpu_idle float CPU idle time portion, the value is weighted between all nodes based on number of cores in each node (0-1, multiply by 100 to get percent)
cpu_system float CPU time portion spent in kernel on the cluster, the value is weighted between all nodes based on number of cores in each node (0-1, multiply by 100 to get percent)
cpu_user float CPU time portion spent by users-pace processes on the cluster. The value is weighted between all nodes based on number of cores in each node (0-1, multiply by 100 to get percent).
egress_bytes float Sum of rate of outgoing network traffic on all cluster nodes (bytes/sec)
ephemeral_storage_avail float Sum of disk space available to Redis Enterprise processes on configured ephemeral disk on all cluster nodes (bytes)
ephemeral_storage_free float Sum of free disk space on configured ephemeral disk on all cluster nodes (bytes)
free_memory float Sum of free memory in all cluster nodes (bytes)
ingress_bytes float Sum of rate of incoming network traffic on all cluster nodes (bytes/sec)
persistent_storage_avail float Sum of disk space available to Redis Enterprise processes on configured persistent disk on all cluster nodes (bytes)
persistent_storage_free float Sum of free disk space on configured persistent disk on all cluster nodes (bytes)
provisional_flash float Sum of provisional flash in all nodes (bytes)
provisional_memory float Sum of provisional memory in all nodes (bytes)
total_req float Request rate handled by all endpoints on the cluster (ops/sec)
