<h1 class="topictitle1">Specify the threshold values</h1>
|
|
<div><p>Setting a threshold for a metric that is being collected by a monitor
|
|
allows you to be notified and, optionally, to specify actions to be taken
|
|
when a certain value (called the <dfn class="term">trigger value</dfn>) is reached. You
|
|
can also specify actions to be taken when a second value (called the <dfn class="term">reset
|
|
value</dfn>) is reached.</p>
|
|
<p> For example, when you create a system monitor, you can specify an i5/OS™ command
|
|
that stops any new jobs from starting when CPU utilization reaches 90% and
|
|
another i5/OS command
|
|
that allows new jobs to start when CPU utilization falls to less than 70%.</p>
|
|
<p>For some metrics, it is appropriate to specify a reset value, which resets
|
|
the threshold and allows it to be triggered again when the trigger value is
|
|
reached. For those thresholds, you can specify a command to be run when the
|
|
reset value is reached. For other metrics (such as the File Status metric
|
|
and the Text metric on file monitors, and any message set on a message monitor),
|
|
you can specify to automatically reset the threshold when the trigger command
|
|
is run.</p>
|
|
<p>You can set up to two thresholds for each metric that the monitor is collecting.
|
|
Thresholds are triggered and reset based on the value at the time the metric
|
|
collection is made. Specifying a higher number of collection intervals in
|
|
the Duration field helps to avoid unnecessary threshold activity due to frequent
|
|
spiking of values.</p>
|
|
<p>You can also choose to add an event to the Event Log whenever the trigger
|
|
value or the reset value is reached.</p>
|
|
<p>On the New Monitor - Metrics page, the threshold tabs provide a place for
|
|
you to specify a threshold value for each metric that you have selected to
|
|
monitor. For example, if you are creating a job monitor, you can set your
|
|
threshold values in the following ways depending on the type of metric you
|
|
have selected:</p>

|

the threshold whenever the monitor detects more than 25 jobs running during

combination of Message ID, Type, and Minimum severity. Each row in the Job
|
|
Log Message table shows a combination of criteria that must be met for a message
|
|
to trigger a threshold. A threshold will be triggered if it meets the criteria
|
|
in at least one row. Use the online help to specify the conditions to trigger
|
|
a threshold. <p>Be careful to monitor the smallest number of jobs that will

give you the information you need. Monitoring a large number of jobs for job

log messages may have a performance impact on your system.</p>
