Summary: 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 Assignee: Denis Magda 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)
