Performing Network Diagnostics

Administrators can perform host-level network diagnostics using the Metacloud Dashboard to check the connectivity of a host and troubleshoot routing issues. The Live Stats page provides the ability to run traceroute <IP ADDRESS/HOSTNAME>, ping <IP ADDRESS/HOSTNAME>, or mtr <IP ADDRESS/HOSTNAME> on every physical host to see the path traffic and verify communication.

Note
The traceroute, ping, and mtr commands are only available using the Metacloud Dashboard.

To run ping:

  1. Log in to the Dashboard.
  2. On the Admin drop-down list, select Controllers or Hypervisors.
  3. Click View Live Stats.
  4. Select the Network tab and click Diagnose Network Connectivity.
  5. Select ping from the drop-down list on the Network Diagnostics dialog box to determine if a specific host is connected.

  2. On the Admin drop-down list, select Controllers or Hypervisors.
  3. Click View Live Stats.
  4. Select the Network tab and click Diagnose Network Connectivity.
