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 | 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 | 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
