+
+Review the metrics for network performance.
+
+- **Unique networks over time**: How many unique SSIDs the device was connected to.
+
+- **Network I/O**: How much data has been transferred (uploads and downloads) between the device and the network.
+
+Review the metrics for device performance.
+
+- **Battery percentage and cycles**: Compares battery percentage to battery health over time. Used to debug potential performance issues possibly related to power-saving measures that are triggered at low-battery levels.
+
+- **CPU usage**: CPU utilization over time. Used to debug slow system performance due to high CPU usage.
+
+- **Memory utilization**: Memory utilization over time. Used to debug performance issues related to an overtaxed memory.
+
+- **Disk I/O**: Displays number of disk bytes read/write operations over time. Used to debug performance errors due to heavy disk operations.
