Rx/Tx drops/erros monitoring

[private55]

I have just setup simple ethernet interfaces monitoring using "SNMP - Interface Statistics". It works very well.
But is there any option to graph the errors say Rx and Tx drops/errors etc on those interfaces?
How can I do that ?

Well, I'd like to avoid answering myself but ... I have found "Interface - Errors/Discards".
I have to create the same graph for several different devices. Do I have to go to each device
and create a graph for it ? Is there any way to create the same graph for several devices at once ?
