Configures the Stuck Thread checker.
The Stuck Threads checker is comparable to the request tracing service, in that it is triggered by exceeding a configured threshold. but in this case it reports on all threads that, when the healthcheck runs, have taken longer than the threshold time.

-
Applies to every server instance in the cluster.
- instance_name

Must correspond to a valid java.util.concurrent.TimeUnit
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
