distribution. You can create a script to configure health probes (see
Monitoring" section on page
CSM periodically executes the scripts at user-configurable intervals.
Before CSM Release 3.1(1a), you could not configure a health probe for a protocol that did not include
the basic health-monitoring code. You can now write probes to customize the CSM for your specific
