Monitoring Request Parameters

The following information describes in detail the monitoring request parameters and offers tips on how to use them.

Specifying When to Send Event - <Notify>

One of the first steps in creating a monitoring request involves specifying the conditions under which you want to be alerted. The following options are available for selecting when to send an alert.

Table 4-2

PSM Status

 

 

 

 

 

When value

You define the conditions under which you wish to be notified for a

 

is…

particular resource using an operator (=, not equal, >, >=, <, <=)

 

 

and a value returned by the monitor (UP, DOWN, UNKNOWN).

 

 

Text values are mapped to numerical values.

 

 

 

 

When value

This notification might be used for a resource that does not change

 

changes

frequently, but you need to know each time it does.

 

 

 

 

At each

This sends notification at each polling interval. It would most

 

interval

commonly be used for reminders or gathering data for system

 

 

analysis. Use this for only a small number of resources at a time,

 

 

and with long polling intervals of several minutes or hours; there is

 

 

a risk of affecting system performance.

 

 

 

Determining the Frequency of Events - <Options>

If you select the When value is… from the <Notify> options, the Options box is displayed. Select one or more of these options:

Table 4-3

PSM Status

 

 

 

 

 

Initial

Use this option for testing a new request to ensure it is sending alerts

 

 

to the desired destinations.

 

 

 

 

Repeat

Use this option for urgent alerts. The Repeat option sends an alert at

 

 

each polling interval as long as the notify condition is met. Use this

 

 

option with caution; there is a risk of high CPU use or filling log files

 

 

and alert windows.

 

 

 

 

Return

Use this option to track when a condition returns to its previous

 

 

value.

 

 

 

These Options are not available if you have selected When value changes or At each interval from the <Notify> list. In these cases the options default to:

•Repeat and Return - Not selected

•Initial - Selected

Setting the Polling Interval - <Polling Interval>

The polling interval specifies how often EMS will check the PSM for changes in hardware status. The polling
