Examples
Example 1 Identifying stuck threads
The following example configures the stuck threads checker to check every 30 seconds for any threads which have been stuck for more than 5 minutes and applies the configuration change without needing a restart:
asadmin healthcheck-stuckthreads-configure --enabled=true --dynamic=true --time=30 --unit=SECONDS --threshold=5 --thresholdUnit=MINUTES
