Add a Service Check to a Device Template

Add a Service Check to a Device Template

To add a service check to a device template, follow the steps below. (See Service Check for configuration best practices.)

1. Log in to Netreo as a user with the Administrator access level or higher.
2. Go to the main menu and select Administration > Templates to open the Device Templates Administration page.
3. Locate the device template to which you would like to add a service check and select its edit icon in the ACTIONS column.
4. In the Template Components panel, locate the Service Checks table.
5. Select the add service check button (+).
   1. In the SERVICE CHECK CATEGORY field, select the category containing the desired service check.
   2. In the SERVICE CHECK field, select the service check to be added.
   3. Click the Select Service Check button.
6. If required by the check, enter appropriate values for check execution in the check-specific parameter fields. These fields vary widely depending on the service check selected. See the documentation for the specific service check for an explanation of each field specific to that check. Please contact a Netreo support engineer if you need assistance.
   • Do not use the exclamation point character (!) in any service check field. Use of this character may cause the check to malfunction.
7. In the DESCRIPTION field (if editable), enter a descriptive name for the check.
   • See below for best practices regarding service check names.
8. In the CONFIGURATION OPTIONS section, configure the alert timing options.
   • If the check is a passive service check, in the ALERT AFTER field, select the number of failures the check is allowed to experience before sending an alert notification (default is 3).
   • If the check is an active service check, in the ALERT AFTER field, select one of the preset timers that determines how long Netreo waits after this check detects a problem before sending an alert notification. (The default value of 5 Minutes is recommended.) Or select Custom to use custom alert timing.
     • To use custom alert timing (see below for best practices regarding custom alert timing):
       1. Select Custom in the ALERT AFTER field to display the ADVANCED OPTIONS panel.
       2. In the CHECK INTERVAL field, enter the number of minutes to wait between executions of the service check under normal conditions (default is 3).
       3. In the ON FAILURE, RETRY EVERY field, enter the number of minutes to wait between executions of the service check after a failure (default is 1).
       4. In the TOTAL FAILURES BEFORE ALERT field, enter the total number of failures the check is allowed to experience before sending an alert notification (default is 3).
9. In the RENOTIFICATION INTERVAL field, enter the number of minutes for Netreo to wait before sending another alert notification if the problem is not acknowledged by a user.
   • Alert notifications are sent to the action groups in the ACTION GROUP field.
   • The default value of 1440 minutes (24 hours) is recommended to minimize alert noise.
   • Setting a value of 0 (zero) disables renotifications.
10. In the ESCALATE AT field, enter the number of alert notifications after the first for Netreo to wait before sending alert notifications to the action groups in the ESCALATION GROUP field, as well as to the groups in the ACTION GROUP field.
    • The default value of 1 means that a total of 2 alerts must be sent before escalation groups start receiving them.
11. In the ACTION GROUP field, select the action group(s) to receive alert notifications before escalation.
12. In the ESCALATION GROUP field, select the action group(s) to receive alert notifications after escalation.
13. In the STATISTICAL GROUP field, select the type that has the greatest relevance to the check. This field determines which statistical calculations this check contributes to for reports.
14. In the NOTES field, enter any notes that you would like included in an alert notification about this check.
15. Select Add to Template.
16. Now follow the instructions in Re-Apply Device Templates After Editing.

Once added to a device template, you may then:

• edit the service check
• delete the service check

by selecting the appropriate icon in its ACTIONS column.

When deleting a service check from a device template, it is not necessary to "Re-apply templates after making changes." As soon as a service check is deleted from a template, Netreo automatically removes that service check from all affected managed devices immediately. (Be aware that other device templates applied to a given managed device may re-add the deleted service check during a discovery poll if they are also configured with it.)
