Please let me know what kind of other info needed to troubleshoot.
And thanks for great exporter!

HO-CORE# show interfaces stats | exclude disabled
^
% Invalid command at '^' marker.

Probably more correct like this:
show interface status | exclude disabled | exclude notconn | exclude sfpAbsent
Will try to patch and test

[l3akage]

Hey,

"show interfaces stats | exclude disabled" is for metrics with "cisco_optics_" prefix, your error is for metrics with "cisco_interface_" so the command should be "show interface". Could you check if you see the interface mgmt0 twice?

[nuclearcat]

I found what is reason, command "show interfaces stats | exclude disabled" doesnt exist on my Nexus.
--- removed patch, its getting malformed---
I did this hack, i know it is not appropriate as patch, but just to test if its a reason. It worked.
Now it returns optics stats

[nuclearcat]

Sorry, patch is at https://pastebin.com/zE1EXFV7 , seems github getting worse every day, can't attach a file or paste code(code tag doesnt work properly) here.

[nuclearcat]

"error gathering metrics: 22 error(s) occurred" seems irrelevant to optics issues, you are right. Its two separate bugs.
I did show interface, mgmt0 is appearing only once.

[nuclearcat]

I think "error gathering metrics: 22 error(s) occurred" is not critical, so closing bug, unless i will find something is missing :)
