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.
