Polling Policies

Polling Policies is a standard configuration interface for adding, editing and removing the polling policies that can be used by the Metric Poller Discovery scheduled job. The scheduled job uses polling policy settings to search for devices and instances to process, create the metrics entries to poll the devices based on selected poller templates, and then assigns thresholds based on the selected threshold group. Essentially, this is a simple, automated and dynamic way to create and maintain Metrics and Threshold settings for certain devices and instances rather than manually creating them using the Polling Assignments interface.

Refer to the Standard Configuration Interface guide for details on interacting with the grid and form.

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

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

Form Fields

  • Name - The name of the polling policy.

  • Description - The description of the polling policy.

  • Policy Status - The status of the polling policy.

  • Match

    • IP Range - An IP address range definition that will be used to restrict the list of devices to process. Each period-delimited portion of the IPv4 range or colon-delimited portion of the IPv6 range can be one of the following:

      • A literal number (i.e. 7).

      • A comma delimited list (i.e. 1,3,5).

      • A range as denoted by two numbers separated by a hyphen (i.e. 1-5).

      • A comma delimited range (i.e. 1-2,7-9).

      • A wildcard as denoted by an asterisk ('*') meaning all possible valid values.

    • CIDR - Type of range expansion to be used:

      • If Enabled, the IP Range field must be an IPv4 of IPv6 address range in CIDR format, for example, 192.0.2.0/8 or 2001:DB8::/32.

      • If Disabled, the IP Range field must be an IPv4 of IPv6 address range in glob format, for example, 192.0.2.* or 2001:DB8::*.

    • Device Name - The Device Name that can be used to restrict the list of matching devices to process (e.g. mth).

    • Device Type - The Device Type that can be used to restrict the list of matching devices to process.

    • Device Category - The Device Category that can be used to restrict the list of matching devices to process.

    • Instance

      • Name - The Instance Name that can be used to restrict the list of matching instances to process.

    • Meta Tag - Used in conjunction with Meta Data, and only the devices with the Meta Tag and Meta Data combination will be processed.

    • Meta Data - Used in conjunction with Meta Tag, and only the devices with the Meta Tag and Meta Data combination will be processed.

  • Assign

    • 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.
