self-polling parameter

In BMC PATROL, a standard parameter that starts a process that runs indefinitely. The started process periodically polls the resource that it is monitoring and emits a value that is captured by the PATROL Agent and published as the parameter value. Self-polling avoids the overhead of frequently starting external processes to collect a monitored value. A self-polling parameter differs from most other parameters that run scripts for a short time and then terminate until the next poll time.
