Group Replication Activity Metrics

Lists the Group Replication Activity metrics and provides a brief description of each.

Name	Description
Member ID	The member server UUID. This string is prefixed with the Member Host for clarity.
Member Host	The host name or IP address of this member. This is retrieved from the member's hostname variable, and is the address clients use to connect.
Member Port	The port on which the server is listening. This is retrieved from the member's port variable.
Transactions Checked	The number of transactions that have been checked for conflicts.
Transactions in Queue	The number of transactions in the queue pending conflict-detection checks. Once the transactions have been checked for conflicts, if they pass the check, they are queued again for application.
Conflicts Detected	The number of transactions that have not passed the conflict-detection check.
Transaction Rows Validating	The number of transaction rows that can be used for certification, but have not been garbage collected. This can be thought of as the current size of the conflict‑detection database against which each transaction is certified.
Transactions Committed All Members	The transactions that have been successfully committed on all members of the replication group, shown as GTID sets. This value is updated at a fixed time interval.
Last Conflict Free Transaction	The transaction identifier of the last conflict-free transaction that was checked.
