High Frequency Poller

This documentation applies to NMS version 5.4. An online version of the software can be found here.

The High Frequency Poller enables you to poll individual objects on a device faster than once per minute. High frequency polling helps you detect momentary spikes in network traffic that last less than one minute. You can negatively affect SevOne NMS performance when you turn on high frequency polling for an excessive number of objects. Please consult with your SevOne Support Engineer if you plan to use high frequency polling for a large number objects.

To access the High Frequency Poller from the navigation bar, click the Devices menu and select Device Manager to display the Device Manager. On the Device Manager, click images/download/attachments/11509821/editnew.png next to a device to display the Edit Device page. On the Edit Device page, click High Frequency Poller.

Click Add Object Poll Frequency or click to display the Add/Edit Object Poll Frequency pop-up.
For a new object, click the Device drop-down and select the device on which the object resides.
For a new object, click the Object drop-down and select the object to poll.
In the Frequency field, enter the number of seconds for how frequently to poll the object. Sub-second polling is possible.
Click Schedule to display the Scheduler pop-up. If you do not define high frequency polling to occur on a schedule, the object is continuously polled at the frequency you define.

Two tabs enable you to define schedule options.
- Select the Periodic tab to define a periodic polling schedule (e.g., every Monday, Wednesday, and Friday from 2:00AM to 4:00AM).
