# This script provides an example of a PVC monitoring plugin script. It will create
|
|
# a simple plugin to check IPMI for power supply reundancy status.
|
|
|
|
# This script can thus be used as an example or reference implementation of a
|
|
# PVC monitoring pluginscript and expanded upon as required.
|
|
|
|
# A monitoring plugin script must implement the class "MonitoringPluginScript" which
|
|
# extends "MonitoringPlugin", providing the 3 functions indicated. Detailed explanation
|
|
# of the role of each function is provided in context of the example; see the other
|
|
# examples for more potential uses.
