Overview
With the Poller Checker tool, you can detect Pollers on monitored nodes or volumes, poll the devices and see the polled details, or update Pollers that are currently assigned to the device in the database with new poller.
Updating Pollers may help resolve issues when polled statistics are unexpected.
This tool is installed by default with each SolarWinds installation into SolarWinds install folder (by default C:\Program Files\SolarWinds\Orion or C:\Program Files (x86)\SolarWinds\Orion ).
- You can mass check for missing Pollers and reapply Pollers using the Poller Checker Tool.
- You can Import and Export the Pollers if needed before applying the changes.
