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

             Summary: Remove TcpDiscoverySpi.heartbeatsFrequency parameter
                 Key: IGNITE-4799
                 URL: https://issues.apache.org/jira/browse/IGNITE-4799
             Project: Ignite
          Issue Type: Bug
            Reporter: Denis Magda
             Fix For: 2.0


{{TcpDiscoverySpi.heartbeatsFrequency}} is no longer used to adjust the heartbeats frequence.
It affects the frequency of metrics messages sent over the cluster ring.

The following has to be done as a part of 2.0 release:
* Remove {{TcpDiscoverySpi.heartbeatsFrequency}} parameter.
* Use {{IgniteConfiguraion.getMetricsUpdateFrequency}} to adjust the rate of metrics messages.
* Make sure {{IgniteConfiguraion.getMetricsUpdateFrequency}} and metrics messages are not
participated in the failure detection process. We have to clean up legacy code in {{ServerImpl}}.

Refer to this discussion for more details:
