<p>Each Knowledge Script represents one or more business or system
|
|
management rules. Knowledge Scripts can monitor the health and performance
|
|
of a managed computer by comparing real-time conditions (such as
|
|
memory usage) against thresholds specified by the Knowledge Scipt.
|
|
Knowledge Scripts also watch for specified events (such as a service
|
|
going down) and can take corrective action (such as restarting the
|
|
stopped service). Knowledge Scripts can also collect data for graphs
|
|
and reports.</p>
|
|
<p> The Knowledge Scripts for the AppManager WMI Agent are configured
|
|
with preset parameters, as described in the following tables. The
|
|
table also lists the preset schedule for each Knowledge Script.
|
|
In the full NetIQ AppManager Suite, you can set the parameters and
|
|
schedule yourself, and perform many other forms of customization.</p>
