cpu usage graph

I could have sworn that the Dude demos at MUM included cpu usage stats/graphing for RouterOS objects. Have tried it myself, but so far it just flat lines. Guess I am missing something (again!).

Any hints?

you can graph anything that has a value which can be seen over SNMP. so enable SNMP on the router, do an SNMP-Walk (from dude) and see which OID you need to use in the graph.

Perfect, many thanks
