6.10.2. Notification —

Identifies the contact methods that have been established for your organization. These methods contain email or pager addresses designated to receive alerts from probes.
The various notification methods available to your organization are listed here on the default Notification screen. The methods are listed according to the user to which they apply.
To create a new notification method, click on the name of the user to whom the notification will apply. The user's User Details ⇒ Notification Methods page appears. Refer to Section 6.9.1.1.7, “User List ⇒ Active ⇒ User Details ⇒ Notification Methods — ” for further information. Click on the title of the notification method to edit the properties of the method.

6.10.2.1. Notification ⇒ Filters

Notification filters allow you to create long-term rules that suspend, redirect, or automatically acknowledge standard notifications or send supplemental notifications. This can be helpful in managing verbose or frequent probe communication.
6.10.2.1.1. Notification ⇒ Notification Filters ⇒ Active Filters
This is the default screen for the Notification Filters tab. It lists all active filters available for your organization. Click the name of the filter to edit the properties of the filter.
To create a notification filter, click the create new notification filter link in the upper right of the screen. Configure each option listed below and click the Save Filter button to create the filter.
  1. Description: Enter a value that allows you to distinguish this filter from others.
  2. Type: Determine what action the filter should take: redirect, acknowledge, suspend, or supplement the incoming notification.
  3. Send to: The Redirect Notification and Supplemental Notification options in step two require an email address to which to send the notifications. The remaining options require no email address.
  4. Scope: Determine which monitoring components are subject to the filter.
  5. Organization/Scout/Probe: This option allows you to select the organization, scout(s), or probe(s) to which this filter applies. To select multiple items from the list, hold the Ctrl key while clicking the names of the items. To select a range of items, hold the Shift key while clicking on the first and last items in the range.
  6. Probes in State: Select which probe state(s) relate to the filter. For example, you may choose to create a supplemental notification for critical probes only. Un-check the box to the left of any state you want the filter to ignore.
  7. Notifications sent to: This is the method to which the notification would be sent if no filter were in place. You may, for example, redirect notifications that would normally go to a user should that individual go on vacation, leaving all other notifications from the probe unchanged.
  8. Match Output: Select precise notification results by entering a regular expression here. If the "Message:" portion of the notification does not match the regular expression, the filter is not applied.
  9. Recurring: Select whether a filter runs continuously or on a recurring basis. A recurring filter runs multiple times for a period of time smaller than the duration of the filter. For example, a recurring filter could run for 10 minutes of every hour between the start and end times of the filter. A non-recurring filter runs continuously between the start and end times of the filter.
  10. Beginning: Enter a date and time for the filter to begin operation.
  11. Ending: Enter an end date and time for the filter.
  12. Recurring Duration: How long a recurring filter instance is active. This field, applicable to recurring filters only, begins at the Beginning time specified above. Any notification generated outside of the specified duration is not filtered.
  13. Recurring Frequency: How often the filter activates.
Notification filters cannot be deleted. However, a filter may be canceled by setting the end date to some time in the past. (Note that the end date must be equal to or later than the start date, or the change fails.) Another method is to select a set of filters from the Active page and click the Expire Notification Filters button in the lower right. These filters are then canceled and appears in the Expired Filters tab.
6.10.2.1.2. Notification ⇒ Notification Filters ⇒ Expired Filters
This tab lists all notification filters whose end date has passed. Expired filters are stored indefinitely; this allows an organization to recycle useful filters as needed and provides a historical record for troubleshooting.
