Create Custom Polling Configurations

Check to see if the threshold you want is already defined. See About Threshold Settings Provided by NNMi.

The Custom Poller feature enables you to take a proactive approach to network management by using SNMP MIB Expressions to specify additional information that NNMi should poll. You can also specify States that should be assigned to polled MIB Expression values, including any thresholds that should be set and monitored.

For example, if you have the HOST-RESOURCES-MIB loaded on your NNMi management server, you might want to monitor additional information using a single MIB variable, such as hrDeviceStatus, so that you can monitor information about a COM (communication) port, Loopback interface, or Ethernet Adapter Status. You might also want to monitor additional information using multiple MIB variables.

For example, disk utilization could be calculated and polled using a MIB Expression similar to the following: (hrStorageUsed / hrStorageSize)

To view the list of MIB Variables supported for a particular node, use the Tools → MIB Browser menu option.

Note the following:

• The MIB variables included in the MIB Expression that you want NNMi to poll must be loaded on the NNMi management server.

• A Custom Poller Policy is applied to the selected node or all the nodes in its specified Node Group as follows:

  • At the time the Policy Active State attribute is set to Active. See Create a Policy for more information.
  • Each time the network is rediscovered as specified by the Rediscovery Interval. See Adjust the Rediscovery Interval for more information.
  • Each time you select Actions → Polling → Configuration Poll from the NNMi console.

• You can also use nnmcustompollerconfig.ovpl to create a Custom Poller configuration.

  When using nnmcustompollerconfig.ovpl to create Custom Poller Policies, you must first create the Node Group to which you want to gather the additional information.

  When using nnmcustompollerconfig.ovpl, each MIB included in the MIB Expression does NOT need to be loaded on the NNMi management server.

  Use nnmcustompollerconfig.ovpl to also enable, disable, configure, list, update, and delete Custom Poller configurations.

• You can configure Custom Pollers locally on a Global Manager or on any Regional Manager.

As an Administrator, to configure Custom Polling you want to perform the following tasks:

1. Prerequisite: Install the MIB files needed for SNMP communication with the devices in your network environment:

   1. Load MIBs
   2. Unload MIBs
2. Enable or Disable Custom Poller

3. Create a Custom Poller Collection

   1. Configure Basic Settings for a Custom Poller Collection
   2. Specify the MIB Variable Information for a Custom Poller Collection
   3. Configure Threshold Information for a Custom Poller Collection
   4. Configure Comparison Maps for a Custom Poller Collection
4. Create a Policy
5. Create a Report Group (NNM iSPI Performance for Metrics)
