You use the settings in a polling group to assign polling parameter values to a particular group of managed devices.

When configuring polling groups, consider device types and roles such as core devices and edge devices. Consider functional roles such as routers that support particular organizations or departments. For example, an ISP could provide various support levels that include different polling cycles. The ISP could charge more for more frequent polling if doing so will result in an earlier resolution of root-cause analysis.

Before modifying any polling groups, determine if the organization enforces any limitations on polling frequency. By default, devices are polled every 4 minutes. Note that some limitations might be based on CPU utilization limits or router traffic limits that no longer apply in the current network. Be sure that you understand how the limitations were determined and, if necessary, suggest that network administrators modify the limits.

Before modifying polling parameters for existing polling groups, ensure that the changes are appropriate for all members in the polling group. If the proposed polling change affects only a limited number of devices in the group, and the current polling adequately supports most devices in the group, then consider creating a new polling group for the devices with the unique polling requirements.
