This variable contains UUID state stored on the node.
Version of the wsrep protocol used.
Sequence number of the last committed transaction.
Total number of writesets sent to other nodes.
Total size (in bytes) of writesets sent to other nodes.
Total number of keys replicated.
Total size (in bytes) of keys replicated.
Total size (in bytes) of data replicated.
Total size of other bits replicated.
Total number of writesets received from other nodes.
Total size (in bytes) of writesets received from other nodes.
Number of writesets commited on the node.
Number of writesets that failed the certification test.
Number of transaction replays due to “asymmetric lock granularity”.
Current length of the send queue. Show the number of writesets waiting to be sent.
Average length of the send queue since the last status query. When cluster experiences network throughput issues or replication throttling this value will be significantly bigger than 0.
Current length of the receive queue. Show the number of writesets waiting to be applied.
Average length of the receive queue since the last status query. When this number is bigger than 0 this means node can’t apply writesets as fast as they’re received. This could be sign that node is overloaded and it will cause the replication throttling.
This variable shows the lowest sequence number in gcache. This information can be helpful with determining IST and/or SST. If the value is 0, then it means there are no writesets in cached in gcache (usual for a single node).
The total time spent in a paused state measured in nanoseconds.
Time since the last status query that replication was paused due to flow control.
Number of FC_PAUSE events sent since the last status query.
Number of FC_PAUSE events sent and received since the last status query.
Average distance between highest and lowest sequence number that can be possibly applied in parallel.
This variable shows parallelization efficiency, how often writests have been applied out-of-order.
This variable shows how often was writeset with higher sequence number applied before the one with lower sequence number.
Average distance between highest and lowest concurrently applied sequence number.
This variable shows how often a transaction has been applied out of order.
This variable currently isn’t being used.
Average distance between highest and lowest concurrently committed sequence number.
Description of the wsrep_local_state variable.
This variable shows the number of entries in the certification index.
This variable, implemented in 5.6.24-25.11, shows the number of cells in the certification index hash-table.
This variable, implemented in 5.6.24-25.11, shows the size of the page pool and/or dynamic memory allocated for gcache (in bytes).
Shows the number of writesets processed while the variable wsrep_causal_reads was set to ON.
Shows the comma-separated list of incoming node addresses in the cluster.
This status variable provides the information regarding the group communication replication latency. This latency is measured from the time point when a message is sent out to the time point when a message is received.
List of UUIDs of the evicted nodes.
Comma separated list of nodes that are considered delayed. The node format is <uuid>:<address>:<count> where <count> is the number of entries on delayed list for that node.
Internal EVS protocol state.
This status variable exposes UUIDs in gvwstate.dat which are galera view IDs (thus unrelated to cluster state UUIDs). This UUID is unique for each node. You will need to know this value when using manual eviction feature.
Number of cluster membership changes happened.
Current number of nodes in the cluster.
This variable shows if the node is connected to the cluster. If the value is OFF, the node has not yet connected to any of the cluster components. This may be due to misconfiguration.
Number of local transactions that were aborted by slave transactions while being executed.
Node index in the cluster
Name of the wsrep provider (usually Galera).
Name of the wsrep provider vendor (usually Codership Oy)
Current version of the wsrep provider.
This variable shows if node is ready to accept queries. If status is OFF almost all the queries will fail with ERROR 1047 (08S01) Unknown Command error (unless wsrep_on variable is set to 0)
