Measure Errors .. ?

[Bici]

Hello everobody,

i'm newbie and have maybe stupid question. I want monitor several Cisco switches and routers. No i'm monitoring bandwitch (octets in and out). And i want to monitor errors (collision, FCS errors, aligment ...) and i don't know how to set up data source type (counter, absolute, gauge, derive) and then how to set up the graph. Could anyone help me please ?

Thanks in advance.
