Polling Assignments

Polling Assignments is a special configuration interface for the manual creation of metric entries that are needed for polling to start working within some applications. In addition to creating the base metric entries, the interface can associate the Metric Thresholds that are used by the thresholding engines to alert when the metric is in violation. Once the metrics are created, they can be viewed and modified in the Metrics interface or by selecting the device now being polled from the Devices navigation link.

Refer to the Form Fields section below for details on how to interact with the grid.

This user interface calls REST methods from api/metric/pollingAssignments.

The UI path for this interface is Configuration -> Metrics -> Polling Assignments.

Form Fields

  • Method - Method to use when polling the metric. It is very important to select the correct method type when creating metrics. If the correct method is not selected, polling may not work correctly:

    • NA - Polling method is not applicable. This type is used for Ping Polling, also known as Metric ICMP Ping Polling.

    • SNMP - Poll the Metric using SNMP.

    • WMI - Poll the Metric using WMI.

    • Other

    • Transaction - Use Transactional polling on the Metric. This type is used for polling by the Transaction Poller.

  • Poller Template - The metric types that will be used when creating metrics. It is important to use the correct poller template for the metric instances being processed so the correct metrics are created. For example, selecting the Default Ping option when processing Device instances will create the Latency, Packet Loss, Ping Jitter and Ping Jitter Utilization metrics.

  • Threshold Group - The group of thresholds to assign to the created metrics. It is important to select the appropriate threshold group so that the correct thresholds are assigned to the created metrics. For example, selecting the Default Ping threshold group when creating the Default Ping metrics so the correct thresholds are assigned to the metrics.

  • Poll Time - How often to poll the metrics, in seconds.

  • Devices - This section will contain all of the available devices with their associated instances. Moving instances to the Selected list will have metrics created for those instances. If you wish to filter down to just "Device" instances, expand the filter bar, then set the "Instance Name" filter method to Regular Expression and filter on ^Device$.
