Alert definition example: network performance for site

In this example, we want to raise an alert if we detect low-performance network sites.

  1. Open the Alert management screen.

  2. On the Alerts tab, click User-defined.

  3. Click Add Alert to access the alert configuration wizard.

Specify basic settings

From the Alert type list, select Internetwork performance .

In the Alert name box, specify a descriptive name that will later help you identify the alert.

Optional: Provide a short description of the alert.

Optional: Modify the default assignment of the alert to the report servers.

By default, the definition is assigned to all available report servers.

Click Next.

The Define Triggering and Propagation Conditions screen of the alert definition wizard is displayed.

Define triggering and propagation conditions

On the Detection settings tab, set the values that will trigger the alert.

  1. Click Add icon Add dimension to add a dimension selection box to the Monitored dimensions section.

  2. Move the mouse cursor over the dimension name and click it to display a complete dimension list.

  3. From the dimension list, select Site .

  4. Leave the default dimension filter settings.

    The default settings ensure that the alert will operate only on real traffic, and that traffic within the site will not be taken into account. Do not add any other dimension filters, unless, for example, you want to limit the applicability of your alert to specific site.

  5. Leave the Comparison mode set to Single (default setting).

  6. From the list of metrics, select Network performance .

  7. Click Add icon Add condition and choose a Value condition from the list.

  8. Set the threshold value to 50 and change the default operator to less than .

    The alert will be raised if the current value of network performance for a site will be below the specified threshold.

In this example, you do not need to configure the Output filters for the alert.

Click the Propagation settings tab to specify how the alert will be propagated.

Set Raise after to 3 to indicate that the alert is to be raised after three events. The threshold needs to be exceeded in three consecutive monitoring intervals, which means 15 minutes if the monitoring intervals are the default length of 5 minutes.

Click Next.

The Configure Alert Notifications screen of the alert definition wizard is displayed.

Configure alert notifications

On the Configure Alert Notifications page of the wizard, specify the notification message template.

In the template, you can use generic textual information and elements selected from the list hidden under the Filter syntax guidelines icon. When a notification is sent, these elements are substituted with the real-traffic data served by AMD.

For example:

Alert ID {0}:
The network performance for a site {1} has exceeded the predefined threshold {4}. Current value: {3}

When delivered, the message may look like this:

Alert ID My Internetwork Alert:
The network performance for a site Default Data Center has exceeded the predefined threshold <50. Current value:  15.45

Assign and enable the notification for a selected user.

If you want to receive a notification by e-mail, go to Actions  ► Enable notifications for a specific report server user listed on the Users tab. If you skip this step, the alerts will be written only to the alert log.

Click Next.

The Review Summary screen of the alert definition wizard is displayed.

Review summary

On the Review Summary page of the wizard, verify your alert settings before you apply them to the report servers.

If you need to change anything, click Previous to go back to the appropriate page of the wizard.

Click Apply.

On the pop-up window you can select the option to save your changes as a draft, if you intend to make more changes now, or to immediately publish the changes if you want to make your changes live now.
