Device health

You can monitor key device health parameters proactively on the Device health dashboard and identify any anomalies from just visualizing the trend charts. You can view the time-trended line graphs for the selected device.

You can investigate potential issues and take corrective actions, as needed, to avoid or mitigate problems. Key metrics that are monitored are the memory and CPU usage.
