VRF discovery on Cisco Nexus 9K

I’ve used my best googlefoo, but I’ve been unable to find a definite answer.
We are considering using LibreNMS for monitoring, but we have several Nexus 9Ks that have multiple VRFs on them.

After researching my issue, I tried to map context using the format : snmp-server context test vrf management, but it did not return the vrf.

Does anybody have any other suggestions?

I’m not sure how to close this, but I found the issue. It was a misconfiguration on the lab switches I was using for testing.
