Troubleshooting Device Reboots

Navigate to the Network Analysis tab > Performance tab > History section > Reboots page to see which devices are experiencing reboots.

  1. Click the device hyperlink in the IP Address column. The Device Viewer opens for that device.

  2. In the Device Viewer, perform the following:

    1. Examine Device > Performance charts. The Reboots chart shows how many times the device has rebooted (click the date hyperlink to change the date). The CPU Statistics and Free Memory charts show the general state of the device before each reboot.

    2. A sawtoothed Free Memory chart that decreases to zero before every reboot, indicates a memory leak. Consider upgrading the device's OS.

    3. If CPU utilization is above 90%, the device is struggling to keep up with the workload. That might be caused by a run-away process or too much network traffic.
