-----------------------------------------

             Summary: Metrics collection must be removed from discovery thread.
                 Key: IGNITE-5644
                 URL: https://issues.apache.org/jira/browse/IGNITE-5644
             Project: Ignite
          Issue Type: Bug
          Components: cache
            Reporter: Mikhail Cherkasov
            Assignee: Mikhail Cherkasov
             Fix For: 2.1


Cache metrics are copied in discovery worker threads. This looks a bit risky because in case of metrics collection may stall the whole cluster. We need to make sure that when the heartbeat message is processed, we already have a metrics snapshot enabled
