[mrtg] Re: Using MRTG to graph Cisco SAA Jitter Stats...

: Hi All,
:
: I'm trying to setup my MRTG to graph the Jitter/RTT/Loss/ect stats that
: I get from the SAA feature in my cisco routers.  After walking the
: proper oid's, I noticed that the instance of the OID changes everytime I
: restart the SAA job.
:
: Is there any way around this?  The (example) OID that I get from the MIB
: is "rttMonJitterStatsNumPositiveDS", so I convert that to
: "1.3.6.1.4.1.9.9.42.1.3.5.1.12" and add the SAA profile (say 3).  With
: just that I get nothing. When I walk it, I see an extra instance number
: after the SAA profile of some 6-7 digit number.  When I use that in the
: mrtg config, all works fine.  But, it doesn't stay constant.  When I
: restart the SAA profile or reboot the router, it changed to some other
: seemingly random number...
:
: I have a bunch of these that I want to setup, but I don't want to have
: to change the OID's for everything everytime I restart the SAA or reboot
: the router.
:
: I tried loading the MIB's in the config file (LoadMIBs:
: d:\mrtg\bin\CISCO-RTTMON-MIB.my), but I got nothing when I used the name
: instead of the full OID.

Stephen,

If your Cisco IOS supports it (12.2 or higher), try "snmp-server ifindex
persist" in your global configs.
This may help keep your if indexing from changing.

Best, Jon
