Andrey Kuznetsov reassigned IGNITE-9679: ---------------------------------------- Assignee: (was: Andrey Kuznetsov) > Document critical workers liveness checking implementation > ---------------------------------------------------------- > > Key: IGNITE-9679 > URL: https://issues.apache.org/jira/browse/IGNITE-9679 > Project: Ignite > Issue Type: Task > Components: documentation > Reporter: Andrey Kuznetsov > Priority: Major > Fix For: 2.7 > > > Newly implemented critical worker thread liveness checks should be mentioned > in Ignite Documentation. Brief description of the functionality follows. > Ignite node has a number of critical worker threads that should be alive and > responsive, otherwise node's health is not guaranteed. These threads monitor > each other periodically and track two aspects for a thread being checked: > - whether it's alive; > - whether it updates its internal heartbeat timestamp. > Both checks use {{IgniteConfiguration.failureDetectionTimeout}} property as a > threshold value. > Whenever at least one of the above conditions is violated, checker thread > logs the error and calls currently configured {{FailureHandler}}. > Liveness checks are enabled by default, but can be disabled through > {{WorkersControlMXBean.healthMonitoringEnabled}} property. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
