 Storm provides a mechanism by which administrators can configure the supervisor to run administrator
supplied scripts periodically to determine if a node is healthy or not. Administrators can
have the supervisor determine if the node is in a healthy state by performing any checks of
their choice in scripts located in storm.health.check.dir. If a script detects the node to
be in an unhealthy state, it must print a line to standard output beginning with the string
ERROR. The supervisor will periodically run the scripts in the health check dir and check
the output. If the script’s output contains the string ERROR, as described above, the supervisor
will shut down any workers and exit. 
 
+If the supervisor is running with supervision "/bin/storm node-health-check" can be called
to determine if the supervisor should be launched or if the node is unhealthy.

 The health check directory location can be configured with:
 
 ```yaml
