126.96.36.199 Modifying or Deleting an AlertUse the Alerts table to manage an existing alert or create a new alert. Highlight an object in the PEM client tree control to view the alerts that monitor that object.You can modify some properties of an alert in the Alerts table (see Figure 4.42):
• The Alert name column displays the name of the alert; to change the alert name, simply replace the name in the table, and click the save icon.
• The Alert template column displays the name of the alert template that specifies properties used by the alert. You can use the drop-down listbox to change the alert template associated with an alert.
• Use the Alert enable? switch to specify if an alert is enabled (Yes) or disabled (No).
• Use the Interval column to specify how often PEM should check to see if the alert conditions are satisfied. Set the Default switch to No and specify an alternate value (in Minutes), or return the Default switch to Yes to reset the value to its default setting. By default, PEM will check the status of each alert once every minute.
• Use the History retention field to specify the number of days that PEM will store data collected by the alert. Set the Default* switch to No and specify an alternate value (in Days), or return the Default switch to Yes to reset the value to its default setting. By default, PEM will recommend storing historical data for 30 days.After modifying an alert, click the save icon (located in the upper-right corner of the table) to make your changes persistent.Click the edit icon to the left of an alert name to open an editor that provides access to the complete alert definition to modify other alert attributes.Use fields on the Alert details dialog (see Figure 4.43) to modify the definition of the selected alert. When you've finished modifying the alert definition, click Save to preserve your changes, or Cancel to exit the dialog without saving any changes.To mark an alert for deletion, highlight the alert name in the Alerts table and click the delete icon to the left of the name; the alert will remain in the list, but in red strike-through font (see Figure 4.44).The delete icon acts as a toggle; you can undo the deletion by clicking the delete icon a second time; when you click the Save icon, the alert definition will be permanently deleted.
