How to Create an SNMP Probe-Based Unit Monitor in Operations Manager 2007

Updated: May 22, 2009

Applies To: Operations Manager 2007 R2, Operations Manager 2007 SP1

A Simple Network Management Protocol (SNMP) probe-based unit monitor queries a Management Information Base (MIB) object for a value and sets the health state based on the result. You can specify two probes: one to set the health state to either Warning or Error, and the other to set the health state to Success.

For more information about SNMP, see Community String at http://go.microsoft.com/fwlink/?LinkId=71187.

To create an SNMP probe-based unit monitor

  1. Log on to the computer with an account that is a member of the Operations Manager Administrators user role or Operations Manager Authors user role for the Operations Manager 2007 management group.

  2. In the Operations console, click the Authoring button.

  3. In the Authoring pane, expand Authoring, expand Management Pack Objects, and then click Monitors.

  4. Click the Change Scope button.

  5. In the Scope Management Pack Objects dialog box, click View all Targets, in the Find text box, type SNMP Network Device, select the SNMP Network Device target check box, and then click OK.

    ImportantImportant
    The target must be the SNMP Network Device object type or an object type derived from it.

  6. In the Monitors pane, expand SNMP Network Device, expand Entity Health, right-click Availability, point to Create a monitor, and then click Unit Monitor.

  7. In the Create a unit monitor wizard, on the Select a Monitor Type page, expand SNMP, expand Probe Based Detection, expand Simple Event Detection, click Event Monitor - Single Event and Single Event, and then click Next.

    noteNote
    You can either select a management pack from the Select destination management pack list or create a new unsealed management pack by clicking New. By default, when you create a management pack object, disable a rule or monitor, or create an override, Operations Manager saves the setting to the Default Management Pack. As a best practice, you should create a separate management pack for each sealed management pack you want to customize, rather than saving your customized settings to the Default Management Pack. For more information, see Default Management Pack.

  8. On the General Properties page, in the Name box, type a name for the SNMP event unit monitor, and then as an option, you can type a description.

  9. In the Parent monitor list, click the appropriate parent monitor, and then click Next.

  10. On the First SNMP Probe page:

    1. For Community String, type the community string.

    2. For Frequency, enter a value for the frequency, and then in the list box, you can leave the default Minutes, or click Seconds, Hours, or Days.

      noteNote
      The minimum value for frequency is 30 seconds, and the maximum value is 604,800 seconds (7 days).

    3. Under Object Identifier Properties, type one or more object identifiers, and then click Next.

  11. On the Build Event Expression page, under Filter one or more events, use the columns in the table to build an expression, and then click Next.

  12. On the Second SNMP Probe page:

    1. For Community String, type the community string.

    2. For Frequency, enter a value for the frequency, and then in the list box, you can leave the default Minutes, or click Seconds, Hours, or Days.

      noteNote
      The minimum value for frequency is 30 seconds, the maximum value is 604,800 seconds (7 days).

    3. Under Object Identifier Properties, type one or more object identifiers and then click Next.

  13. On the Build Event Expression page, under Filter one or more events, use the columns in the table to build an expression, and then click Next.

  14. On the Configure Health page:

    1. For the First Event Raised row, click the name in the Operational State column and type a display name for this condition. Click the health state in the Health State column, and then click Error, Warning, or Success.

    2. For the Second Event Raised row, click the name in the Operational State column and type a display name for this condition. Click the health state in the Health State column, and then click Error, Warning, or Success.

      noteNote
      One of the two events must be configured to set the health state to Success.

    3. Click Next.

  15. On the Configure Alerts page, set the properties of the alert, and then click Create.
