Hi does anyone know the OIDs for NNTP, I want to monitor NNTP sessions en bandwidth with MRTG.
OID for NNTP (all stats). If you want per interface, you'll have to dig around a bit.
There are no OIDs for NNTP. Really, you could have said TCP here, and the same would have been true. In order to monitor the actual NNTP traffic, you would need to have an RMON probe or something similar that analyzes the transit traffic, and allows you to break out the different protocols.
That said, there may be some NNTP SNMP instrumentation on your NNTP server that you could use to graph connections in MRTG.
