Result for the cluster_info command

Fields

cluster_state: ClusterState

State is ok if the node is able to receive queries. fail if there is at least one hash slot which is unbound (no node associated), in error state (node serving it is flagged with FAIL flag), or if the majority of masters can’t be reached by this node.

cluster_slots_assigned: usize

Number of slots which are associated to some node (not unbound). This number should be 16384 for the node to work properly, which means that each hash slot should be mapped to a node.

cluster_slots_ok: usize

Number of hash slots mapping to a node not in FAIL or PFAIL state.

cluster_slots_pfail: usize

Number of hash slots mapping to a node in PFAIL state. Note that those hash slots still work correctly, as long as the PFAIL state is not promoted to FAIL by the failure detection algorithm. PFAIL only means that we are currently not able to talk with the node, but may be just a transient error.

cluster_slots_fail: usize

Number of hash slots mapping to a node in FAIL state. If this number is not zero the node is not able to serve queries unless cluster-require-full-coverage is set to no in the configuration.

cluster_known_nodes: usize

The total number of known nodes in the cluster, including nodes in HANDSHAKE state that may not currently be proper members of the cluster.

cluster_size: usize

The number of master nodes serving at least one hash slot in the cluster.

cluster_current_epoch: usize

The local Current Epoch variable. This is used in order to create unique increasing version numbers during fail overs.

cluster_my_epoch: u64

The Config Epoch of the node we are talking with. This is the current configuration version assigned to this node.

cluster_stats_messages_sent: usize

Number of messages sent via the cluster node-to-node binary bus.

cluster_stats_messages_received: usize

Number of messages received via the cluster node-to-node binary bus.

total_cluster_links_buffer_limit_exceeded: usize

Accumulated count of cluster links freed due to exceeding the cluster-link-sendbuf-limit configuration.

cluster_stats_messages_ping_sent: usize

Cluster bus PING sent (not to be confused with the client command ping).

cluster_stats_messages_ping_received: usize

Cluster bus PING received (not to be confused with the client command ping).

cluster_stats_messages_pong_sent: usize

PONG sent (reply to PING).

cluster_stats_messages_pong_received: usize

PONG received (reply to PING).

cluster_stats_messages_meet_sent: usize

Handshake message sent to a new node, either through gossip or cluster_meet.

cluster_stats_messages_meet_received: usize

Handshake message sent to a new node, either through gossip or cluster_meet.

cluster_stats_messages_fail_sent: usize

Mark node xxx as failing.

cluster_stats_messages_fail_received: usize

Mark node xxx as failing.

cluster_stats_messages_publish_sent: usize

Pub/Sub Publish propagation, see Pubsub.

cluster_stats_messages_publish_received: usize

Pub/Sub Publish propagation, see Pubsub.

cluster_stats_messages_auth_req_sent: usize

Replica initiated leader election to replace its master.

cluster_stats_messages_auth_req_received: usize

Replica initiated leader election to replace its master.

cluster_stats_messages_auth_ack_sent: usize

Message indicating a vote during leader election.

cluster_stats_messages_auth_ack_received: usize

Message indicating a vote during leader election.

cluster_stats_messages_update_sent: usize

Another node slots configuration.

cluster_stats_messages_update_received: usize

Another node slots configuration.

cluster_stats_messages_mfstart_sent: usize

Pause clients for manual failover.

cluster_stats_messages_mfstart_received: usize

Pause clients for manual failover.

cluster_stats_messages_module_sent: usize

Module cluster API message.

cluster_stats_messages_module_received: usize

Module cluster API message.

cluster_stats_messages_publishshard_sent: usize

Pub/Sub Publish shard propagation, see Sharded Pubsub.

cluster_stats_messages_publishshard_received: usize

Pub/Sub Publish shard propagation, see Sharded Pubsub.
