Create a Custom Poller Collection

[This is the context-sensitive help topic for the Custom Poller Collection form]

A Custom Poller Collection defines the information you want to gather (poll) as well as how NNMi reacts to the gathered data. For example, by default, you can specify whether you want to do either of the following:

• Configure Thresholds or Comparison Maps that map polled MIB Expression values to States and optionally causes incidents to be generated.
• Include State changes in calculations for the source Node's Status.

Each Custom Poller Collection can have one or more Policies. Each Policy specifies the Node Group from which you want to gather the additional information.

Instance Custom Poller Collection Type only. The first time a MIB Expression is validated with discovery information, the results appear in a Custom Polled Instance object. The Polled Instance object is updated whenever a change in State occurs and includes the most recent polled value that caused the State to change.

To create a Custom Poller Collection, do the following:  

1. Navigate to the Custom Poller Collections tab.

   1. From the workspace navigation panel, select the  Configuration workspace.
   2. Expand the Monitoring folder.
   3. Select the Custom Poller Configuration form.
   4. Select the Custom Poller Collections tab.
   5. Do one of the following:
   • To create a Custom Poller Collection, click the New icon.
   • To edit a Custom Poller Collection, double-click the row representing the configuration you want to edit.
2. Make your configuration choices (see table).

3. Click   Save and Close.

   Note When you save a Collection configuration, each Policy for that Collection changes to Active State Suspended. When you are finished making your Custom Poller Configuration changes, set the Active State to Active for each of the policies in the Custom Poller Collection that you want to be in use. To make a Policy active, access the Custom Poller Configuration: Policy tab, open each associated Policy, and change the Active State to Active. See Create a Policy for more information.

   To verify that Custom Poller is working as expected, see the report on the Custom Poller tab in Help → System Information.

Custom Poller Collection Configuration Tasks

Task	How
Configure Basic Settings for a Custom Poller Collection	Provide the basic information for a Custom Poller Collection configuration.
Specify the MIB Variable Information for a Custom Poller Collection	You specify the MIB Expression you want to poll. Use the MIB Expression editor to specify the MIB Variable and any constant or arithmetic operator you want to use in the MIB Expression. Navigate the MIB Tree to select each MIB OID you need to define your MIB Variable.
Configure Threshold Information for a Custom Poller Collection	Optional. Instance Custom Poller Collection Type only. Specify minimum and maximum threshold values for the MIB Expression results and assign these thresholds to States.
Configure Comparison Maps for a Custom Poller Collection	Optional. Instance Custom Poller Collection Type only. Use Comparison Maps to assign a State value to a potential polled value of a MIB Expression.
