At this url you will find the list of metrics that the nic_monitor currently supports:

Note that the nic_monitor probe is only capable of local monitoring when a robot is installed.

Openstack

OpenStack network troubleshooting and monitoring seems to imply running local commands and leveraging the output.

e.g., ping, tcpdump, tracert/traceroute, etc.

We do have the nexec probe (runs commands) as well for scripting interfaces that might be able to be used to run commands/scripts but that may be locked down by security.

openstack probe v1.38 hasn't been updated since 2019 but you can try it.

The openstack probe supports monitoring the following incoming and outgoing network usage statistics of the instances:

- Bytes and Bytes per Second
- Packets and Packets per Second

OpenStack SNMP Support

If the OpenStack SNMP driver is implemented, you may be able to use the snmpcollector (or a simple approach via use of snmpget) to monitor device status, utlization, and errors you mentioned. You can check the OpenStack docs for montoring options including SNMP.
