SNMP add custom mib

Problem/Question

Hi
I just set up SNMP on my netdata instance to monitor my switch.
Sadly I just get very very little stats, like just some networking stats, uptime and port status, many metrics are missing which I can otherwise view via snmpwalk.

Cisco is offering a custom MiB file for that snmp monitoring, how do I import that into netdata?
I’m currently using the agent to monitor the snmp device.

Relevant docs you followed/actions you took to solve the issue

Environment/Browser/Agent’s version etc

Browser: Firefox 130.0
Agent: netdata v1.47.1

What I expected to happen

I expact a way to import a custom MIB file or get more metrics by default.

Here an overview what metrics are currently displayed:

  • snmp.device_uptime
  • snmp.device_net_interface_oper_status
  • snmp.device_net_interface_admin_status
  • snmp.device_net_interface_discards
  • snmp.device_net_interface_errors
  • snmp.device_net_interface_broadcast
  • snmp.device_net_interface_multicast
  • snmp.device_net_interface_unicast
  • snmp.device_net_interface_traffic

While I appreciate those metrics, most of them don’t really tell anything about the system, I’d love to get other metrics like hostname, cpu, ram, disk etc. etc.

Hi. That is not possible/not supported at the moment.

Oh I see.

So there is currently no way of getting “more” metrics??
