The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Polling devices at regular intervals help you detect devices and check their health. Managed network devices are polled periodically to synchronize the device data with the Cisco Prime Collaboration database.
Cisco Prime Collaboration polls devices to:
Check whether the devices are reachable
Check whether the devices are up and running
Display up-to-date device data
Cisco Prime Collaboration is configured with default settings for polling parameters. You can use the defaults, edit them, or restore them at any time. Depending on how important a device group is, you can increase or decrease the polling interval to do either of the following:
Enables you to poll data for device power supply, fan, voltage, and temperature sensor.
Enables you to poll data for device interfaces and ports; for example, device communication over HTTP.
Data polling from interfaces and ports are controlled at the device level; that is switches have a specific polling setting, and this setting determines when the switch ports are polled.
Enables you to poll data for device reachability, processor, CPU, and memory utilization.
Enables you collect performance and capacity planning data that is used to view Performance Graphs.
You can access the performance graphs through the Alarms & Events page, Device 360 degree view, and Diagnostics Summary pages.
Enables you to poll data for device connectivity, system status, and call quality.
Service settings provide data for service issues, such as cluster connectivity and telephony configurations.
The polling parameters vary based on the device type that you select.
You can customize the polling interval for the parameters based on your business needs. However, we recommend that you select the Use Best Practice labelled polling interval. For each of the polling setting, you can also view the associated events when there is a threshold violation ( ). For event description and device type, see the Supported Alarms and Events for Prime Collaboration Assurance and Analytics Business.
If you do not want to poll any specific data, you can disable the polling settings using the Disable option.
When you change the polling parameter settings, the changes are applied for the entire group and not just the device. Polling Parameters are displayed in
page, when you select a Device Group.From the Polling Parameters page, you can perform any of the following tasks:
When you view polling settings for a device group, you can see the devices that are members of the device group, and you can see the default and current values for the polling parameters.
When you edit Cisco Prime Collaboration polling parameters, you edit settings that are associated with device groups, not with individual devices. When you have finished all changes to polling parameters (and thresholds and priorities), apply all changes.
