# Monitoring

## getDeviceAssociatedMonitors

The API returns a complete list of monitors associated with the device, including performance monitors, application monitors, Windows services, and scripts, along with their last polled values and status.

Note: If you're looking for performance monitor details alone, we recommend using the [getLastCollectedValues](https://www.manageengine.com/network-monitoring/help/restapi/monitoring.html#getLastCollectedValues) API, which is more efficient and returns the last collected values of the monitors along with other properties.
