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 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 local transactions that were aborted by slave transactions while being executed.
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
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.
Time since the last status query that replication was paused due to flow control.
FC_PAUSE events sent since the last status query.
FC_PAUSE events sent and received since the last status query.
Average distance between highest and lowest sequence numbet 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
Shows the number of writesets processed while the variable
wsrep_causal_reads was set to
Shows the comma-separated list of incoming node addresses in the cluster.
Number of cluster membership changes happened.
Current number of nodes in the cluster.
Node index in the cluster
Name of the wsrep provider (usually
Name of the wsrep provider vendor (usually
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
