In JIRA Data Centre some operations require the a lock to be placed across all nodes for operations that should only be operated on one node at a time, for example taking a backup of the index. This Health Check will check the age of the cluster locks and report a warning in the event that a cluster lock is found that is older than five minutes.

Understanding the Results

IconResultWhat this means
The health check passed successfully.No lock was detected that is older than five minutes.
Node '<node-name>' has been holding cluster lock, '<lock>', for <seconds> seconds.A lock has been held for longer than five minutes.
