[ https://issues.jboss.org/browse/WFLY-6321?page=com.atlassian.jira.plugin.... ] Richard Achmatowicz commented on WFLY-6321: ------------------------------------------- The thread pools of interest in JGroups: - created in org.jgroups.protocols.TP - thread pools: -- regular -- OOB -- internal The thread pools of interest in Infinispan: - majority created in org.infinispan.factories.NamedExecutorsFactory - thread pools: -- transport -- remote -- notification -- persistence -- expiration -- replicationQueue -- stateTransferExecutor -- totalOrderExecutor -- async -- timeout There are two approaches to monitoring thread pools used here: - dump thread pool statistics every X calls to the Executor - dump thread pool statistics every X seconds For each thread pool, we present these statistics: - pool: the number of threads currently available in the pool - activePool: the number of active threads (i.e. threads which are executing some task) - queuedTasks: the number of queued tasks waiting for an available thread - completedTasks: the number of tasks completed by some thread in the thread pool Rejected execution exceptions are also monitored; these occur when the thread pool is "overwhelmed". -- This message was sent by Atlassian JIRA (v6.4.11#64026)
