Hi @clavister
So you want to display only the interfaces with in/out discards, right?
I would suggest you try filtering the "show int counters errors" output since it is much simpler and has better structure.
Since you want to make a graph, I suppose you are not doing the parsing manually. So you can also take advantage of the NXOS built-in programmability features. For example, use " | json " at the end of a command, and you will get the output in json format.
If you really want to go the "hard way" and filter the show interface, you can try this:
show interface | exclude " 0 input discard" | exclude " 0 output discard" | grep "port\-cha\|Ethernet[1-9]\|discard" | grep -B 1 discard
The command will basically display 1 line before discard line which is either another discard value, either the corresponding interface.
Also, I made some adjustments on the cmd to not display the "Hardware" lines.
Cheers,
Sergiu
