             Summary: Edge-chasing deadlock detection monitoring
                 Key: IGNITE-10841
                 URL: https://issues.apache.org/jira/browse/IGNITE-10841
             Project: Ignite
          Issue Type: Bug
          Components: mvcc
            Reporter: Ivan Pavlukhin

A deadlock detection process introduces several effects in the system which should be visible
for an administrator. Here are couple of such effects:
1. Rolling back deadlocked transactions.
2. Introducing messaging overhead even in case when there are not deadlocks.

Several metrics can be exposed via JMX and/or SQL view. Here are some candidates:
1. Number of detected deadlocks and involved transactions.
2. Sent/received deadlock detection messages count.
