Creating generic threshold poll definitions

Use the Poll Definition Editor to create new generic threshold poll definitions.

1. Click the Administration icon and select Network > Network Polling.
2. Click Add New .
   The New Poll Definition Type Selection page is displayed.
3. Select Generic Threshold from the list and click OK.
4. In the Poll Definition Editor, under the General tab, complete the General Properties fields as follows:

   Name

   Specify a unique name for the poll definition. Only alphanumeric characters, spaces and underscores are allowed.

   Type

   This field is disabled. The Polling engine, ncp_poller, automatically populates this field once this poll definition is included as part of an enabled poll policy.

   Event ID

   This field is disabled. The Polling engine, ncp_poller, automatically populates this field once this poll definition is included as part of an enabled policy. The Event ID field is populated as follows:

   • If this is a new poll definition, then the Event ID field is populated with the value POLL-polldef, where polldef is the name of the current poll definition.
   • If you created a poll definition by copying an existing poll definition, then the Event ID contains the same value as the copied poll definition.

   Note: Some of the older default polls have Event ID fields that do not use the POLL-polldef naming convention.

   Event Severity

   Specify a valid number for the severity. The severity level must correspond to a valid severity level as defined in IBM Tivoli Netcool/OMNIbus.

   Description

   Type a short description of the poll definition.

5. Click the Classes tab. In the Classes tree, select the check boxes of the required classes.
   Attention: If you leave all classes unchecked, then the system polls all devices that match the scope defined in the poll policy that uses this poll definition.
6. Optional: Click the Interface Filter tab and build the filter against the required fields.

   The Table field is prepopulated with the interfaces table.

   Note: When polling for interface data (not ping polling or remote ping polling), by default, all interfaces in the SNMP interfaces table of the device are polled, whether they were discovered or not. Interfaces might not be discovered if you configured interface filtering for discovery, or for some other reason, for example that they were inaccessible at discovery time. Undiscovered interfaces are still polled unless you configure a filter on the interface records in the NCIM database for the poll. If you add any interface filter to this poll, the filter is applied to the interface records in the NCIM topology database, and only those interfaces are polled. Only the subset of the discovered interfaces that also matches the filter is polled.
7. Click the Trigger Threshold tab. Build the formula that specifies the threshold by using one of the following methods:
   • In the Basic area, use the fields and options to build a formula. To select values from the MIB tree, click Open MIB Tree .
   • In the Advanced area, type the required eval statement in Object Query Language (OQL).
8. Specify the message that is displayed in the Event Viewer for the generated event:
   1. In the Event description field, type the message.
   2. To insert the MIB variables in the field, click Open MIB Tree . Set the message to include either the current or previous SNMP value, or the SNMP index, and click OK.
9. Required: Click the Clear Threshold tab. Every generic threshold poll definition requires a clear threshold. Build the formula that specifies the threshold by using one of the following methods:
   • In the Basic area, use the fields and options to build a formula. To select values from the MIB tree, click Open MIB Tree .
   • In the Advanced area, type the required eval statement in Object Query Language (OQL).
   Tip: If you want the threshold to be cleared manually, create a clear threshold that will not be reached.
10. Specify the message that is displayed in the Event Viewer for the generated event:
    1. In the Event description field, type the message.
    2. To insert the MIB variables in the field, click Open MIB Tree . Set the message to include either the current or previous SNMP value, or the SNMP index, and click OK.
11. Click Save, then click OK.
