There are no network metrics in the host dashboard or showing as n/a. The log files show the following errors:
HostAgents/5.6.5/UnixAgent/Monitor@<linux-agent> DEBUG [Quartz-9798] com.quest.remoteos.collectors.linux.LinuxCollector - /sbin/ethtool eth1 command returned 75 - stderr: Cannot get device settings: Operation not permitted
Cannot get wake-on-lan settings: Operation not permitted
Cannot get message level: Operation not permitted
Cannot get link status: Operation not permitted
Could not process metric query command: /usr/bin/env LC_ALL=C /sbin/ethtool eth9. Error: process exited with code 75
Please have a look at this documentation to set up the agent properly to monitor Unix system: About the UnixAgent "Configuring secure launcher permissions using sudo"
Another workaround would be, to setuid for the ethtool to root. This will let the Foglight user be able to run the binary without sudo. Unfortunately it will mean that all other users would also be able to run the binary. In the case of ethtool this should not be much of an issue since it only displays data.
