Configure Windows Management Instrumentation (WMI) Monitor to publish device information to the NMC

The Windows Management Instrumentation (WMI) Monitor can be configured to retrieve information about any device and publish this information to the Network Management Console (NMC). You can achieve this using ConfigWMIMonitor. This process can be an effective way to view the device state within the NMC.

Notes: This out-of-the-box mechanism does not create adminPager messages, nor does it cause failovers to take place if the hardware fails — it only enables the device to be visible within the NMC. When this device is displayed within the NMC, it is shown with static icons rather than state-specific icons.

Configuration changes to the WMI Monitor must be followed by a Common service restart for it to take effect in the NMC.

To enable additional logic to be performed, and/or to enable the NMC to show icons that identify the state of the device, you must create a component that the WMI Monitor will call during the processing of the retrieved device information. This component can be specified while you configure the device monitoring characteristics.

For more information, refer to Creating Project Specific WMI Monitor Components for Any Device.

To configure WMI Monitor to publish device information to the NMC

1. On the desktop, double-click the Windows PowerShell for DNA shortcut.

   Windows PowerShell for DNA opens.

2. To execute the Config WMI Monitor, execute the following commands:

   set-silo Common

   ConfigWMIMonitor

   The OASyS DNA WMI Monitor Wizard opens.

   

3. Select Next.

   The Select Action page appears.

   

4. Select Add new configuration, and then select Next.

   The Select the Namespace/Class to be monitored page appears.

   

5. For a new WMI Namespace to be configured, select the desired namespace in the left-hand panel.

   The Available classes pane is populated.

   

6. Select the class that you want to monitor, and then select Next.

   The Configure Class page appears.

   

7. Configure the following fields:

   1. In the Class / Device Name To Appear in NMC field, enter the desired class or device name.

   2. From the Poll Interval (seconds) dropdown menu, select the interval that this device will be checked.

   3. Select Select Field, to select the device identifier field that uniquely identifies this device.

8. Select Next.

   The Choose Fields page appears.

   

9. From the Available Class Fields pane, select the fields you want publish, and then select the icon to add fields and the icon to remove fields.

10. Optional: To add a custom field that you want to appear in the NMC, do the following:

    1. Select Add Calculated Field.

       The Calculated Field dialog box appears.

       

    2. Configure the following fields:

       1. In the Name field, enter the name of the custom field.

       2. In the Calculation field, define the calculation of the custom field to be based on either an existing class field, a numeric value, a boolean, or a string.

       3. Select Ok.

       The Choose Fields page appears.

11. Select Next.

    The Define Health State page appears.

    

12. Optional: To ensure a field is displayed in the NMC, ensure the Display Field in NMC checkbox is selected. If you clear this checkbox, proceed to step 13.

    Note: If you decide to define the health state conditions, consider defining a custom field called HealthStateInfo as performed in step 9. This custom field enables the NMC to display the bad or warning state messages.

13. Optional: Configure the following fields:

    1. In the Bad Health State Condition field, define the bad health state condition.

    2. In the Bad Health State Message field, define the message that will be published to the admin pager when the bad health condition is met.

    3. In the Warning Health State Condition field, define the warning health state condition.

    4. In the Warning Health State Message field, define the message that will be published to the admin pager when the warning health condition is met.

14. Select Next.

    The Revise Query page appears.

    

15. The WMI Monitor process retrieves device information using asql-query-like language. To fine tune this query, in the Where Clause field, enter additional information for the query. For example, the example query above retrieves device information of "logical disks" type, specifically hard-drives (DriveType=3).

16. Select Next.

    The Summary page appears.

    

17. Select Next.

    The Configuration Successfully Updated page appears.

    

18. Select either New Configuration or Exit, and then select Finish.
