Events and Device Groups

This section describes how to suppress an event for a device group.

Events are messages that are triggered when a specific condition is met. For example, an event can signal a server has gone down, that a device is exceeding CPU or disk-space thresholds, that communication with a device has failed, or simply display the status of a managed element.

Events are displayed on the Events page or on the Event Console page (Events > Classic Events, or the Events tab in the classic SL1 user interface). When you suppress an event, you are specifying that in the future, if this event occurs again on the same device, the event will not appear in the Event Console page. Basically, you are saying that if the event occurs again on the same device, you do not want to be notified.

If a suppressed event occurs on a different device, it will appear on the Events page or on the Event Console page.

You can suppress an event for a device group. The event will then be suppressed for all devices in the device group. The event will also be suppressed for all child device groups and their devices.

NOTE: For general details on events, see the section on Events.

Use the following menu options to navigate the SL1 user interface:

  • To view a pop-out list of menu options, click the menu icon ().
  • To view a page containing all of the menu options, click the Advanced menu icon ().

Searching Events by Device Group

Events are messages that are triggered when a specific condition is met. For example, an event can signal a server has gone down, that a device is exceeding CPU or disk-space thresholds, that communication with a device has failed, or simply display the status of a managed element.

Events are displayed on the Events page or on the Event Console page (Events > Classic Events, or the Events tab in the classic SL1 user interface). On either of these pages, you can search for Device Group Names and Device Group IDs to find events that occurred on devices that are members of the specified Device Group.

The search fields on the page allow you to filter the entire list of displayed events by a single parameter. SL1 will update the page and display only events that have a matching parameter.

To use the search fields, enter values in the Search drop-down list and the Text field:

  • Search. You can select from a number of parameters, including:
  • Device Group ID. Unique ID for the device group associated with the event.
  • Device Group Name. Name of the device group associated with the event.
  • Text. For each search parameter, you must enter text to match against. SL1 will search for events that match the text, including partial matches. Text matches are not case-sensitive. You can use the following special characters in each filter:
  • , (comma). Specifies an "or" operation. For example:

"dell, micro" would match all values that contain the string "dell" OR the string "micro".

  • & (ampersand). Specifies an "and" operation. For example:

"dell & micro" would match all values that contain the string "dell" AND the string "micro".

  • ! (exclamation mark). Specifies a "not" operation. For example:

"!dell" would match all values that do not contain the string "dell".

To perform another search on the results of the previous search:

  1. Click the plus sign () to the left of the Refresh Timer.
  2. This adds another Search field and Text field to the top of the page. This second search will search only the results from the first search.
  3. You can add as many Search and Text fields as you need.

NOTE: You can save the results of a Global Search as a Custom View.

Suppressing an Event for a Device Group

You can suppress an event for a device group. When you do so, you are suppressing the event for all devices in the device group (and optionally, any child device groups).

NOTE: To be able to suppress an event for a device group, the Device Group Editor page for that device group must include Event Suppression in the Visibility field.

To suppress an event for a device group:

  1. Go to the Event Policies page (Events > Event Policies, or Registry > Events > Event Manager in the classic SL1 user interface).

  2. Click the Actions icon () for the event policy you want to edit and select Edit.

  3. When the Event Policy Editor page appears, select the Suppressions tab.

  4. In the Suppression tab, you can define or edit the following:

    • Device Groups. Specifies the device groups on which you can suppress the event. To suppress the event on all devices in a device group, click the Select Device Groups button and select one or more device groups from the Available Device Groups window. The device group(s) will then appear in the list under Device Groups. To remove a device group from the list, click the Close icon () next to the device group in the list.

      • You can use the box at the top of the Available Device Groups field to filter the list of device groups. You can enter an alpha-numeric string in the box, and the Available Device Groups field will include only device groups that match the string.

      Only device groups that have Event/View Suppression enabled will appear in this field.

  5. Click Save to save your changes to the event policy.

Suppressing an Event for a Device Group in the Classic SL1 User Interface

To suppress an event for a device group in the classic SL1 user interface:

  1. Go to the Event Policy Manager page (Registry > Events > Event Manager).
  2. In the Event Policy Manager page, find the event you want to suppress. Click its wrench icon ().
  3. When the Event Policy Editor page appears, select the Suppressions tab.
  4. In the Suppressions tab, you can define or edit the following:
  • Available Device Groups. Device groups for which you can suppress the event.
  • Suppressed Device Groups. Device groups for which the event is already suppressed.
  1. You can use the arrow buttons (<< and >>) to move device groups from the Available and Suppressed lists.
  2. Click the Save button to save your suppressions.
