[mrtg] Re: MRTG/RRD - Application monitoring.

FYI, I was advised by Cisco that configuring NBAR causes all packets
passing through that interface to be process-switched instead of using
CEF, which can cause a big CPU hit, contingent upon the amount of traffic
passing though it.

Hi Ram,

If you want to monitor the different protocols at the interfaces of the
Cisco routers you can use NBAR.
When you have NBAR up and running, you need to find out which oid's you
want to monitor from the CISCO-NBAR-PROTOCOL-DISCOVERY-MIB.
With this information you have to build your mrtg config file.
If you don't want to re-invent the wheel you can ask this list for sharing
a template config file with NBAR ;-)

Hth,

Jan.

Hello,

I have setup an MRTG/RRD to monitor our WAN links (all cisco
routers/switches) and it is working fine.

I would like to monitor the applications (notes, SAP, nebios, http,
citirx, etc.) flowing through the links by polling the cisco routers'
interfaces (2600, 3600 and 7200 series).

Need some pointers on this.

OS version - Windows XP
MRTG Version - 2.10.13
Perl   version - 5.6.1
RRD Tool version - 1.0.35
routers2.pl,
routers.cgi v2.11

Thanks in advance for the time.

Ram
