Polling the network

Polling is for SNMP metric collection from the devices in your network and to store the data in the database. You can collect the metrics from different devices and entity types based on the data in the Management Information Base (MIB) variables of the devices.

About this task

Typically, network polling for resources is performed every 300 seconds, which is the default polling interval.

High-level tasks in polling the network in Network Performance Insight® are as follows:
  • Scoping
  • Polling interval

Procedure

  1. Install the Technology Pack content that comes with the predefined formulas, metrics, and MIB files.

    Network Performance Insight supports SNMP metrics, vendor-specific IP SLA metrics, and device health metrics for Cisco, Huawei, and Juniper devices. Apart from using the predefined metrics, you can also create or modify metrics and formulas. For more information, see Rapid SNMP device onboarding.

  2. Optional: Configure the polling interval from Polling Configuration page under System Configuration.

    By default, polling is initiated once in every 300 seconds. If you want to set a different value, use the Polling Configuration page.

    For more information, see Configuring the metric polling interval.

  3. Configure the poll definitions for the resources to be polled.
