RE: (usr-tc) oid for harc cpu usage
Actually, the question was "Is there an oid in the new release of code to find the cpu usage of the Harc?", not the delta CPU usage. While Mike's answer at least attempts to answer the question, it sounds like the answer is actually "No". The delta CPU usage has been part of the HARC MIB for some time, and while it may serve a purpose, it certainly doesn't show the total CPU usage. Dwayne was simply asking if there is an OID in the new code that shows the total CPU usage, once again, sounds like the answer is "No". Leaving all the discussion about the older delta CPU usage OID out, does anybody know if 3Com have included an OID to measure true CPU usage in the new HARC code. Thanks, Chris

Since nobody ever answered the original question about the OID, here's an MRTG entry...
Target[foo]: 1.3.6.1.4.1.429.4.3.1.13.0&1.3.6.1.4.1.429.4.3.1.14.0:public@foo MaxBytes[foo]: 100 Title[foo]: CPU usage on HiPer ARC foo Options[foo]: gauge YLegend[foo]: percent cpu ShortLegend[foo]: percent cpu LegendI[foo]: 1-min: LegendO[foo]: 5-min:
And yeah, most of the time it just graphs zero because it's reporting only "above average" usage or something similar -- but occasionally it will graph some spikes when you get really busy.

So it's just named poorly?
From you explination.. as long as the last 3 values are 0 then the CPU is just not above some threshold set in flash.... OK, next question: what's that value? Or is it safe to say that as long as the values are 0 it's just nothing to worry about?
Thanks

Quoting Paul Farber <farber@admin.f-tech.net>:
historically sho cpu utilization has been broke. On both ARC's I have 4.1.59 and sho cpu util are 0% (with 250+ calls on it!)
No - show cpu is not broken. It shows 0% with 250+ calls is normal. The HiPer arc is designed to show the CPU utilization only when it reaches the level of calls/flash updates/route tables and any other routing related activity exceeds the bench mark. Which basically means you will see show cpu activity instantaneously if you do a save all and do a show cpu at that instance.
What it is that being a embaded system, the HiPer arc CPU is always being utilized, so they have a bench mark, once you exceed the bench mark the cpu utilization shows. Typically for normal call volumes you will not see any cpu utilization, do a lot of l2tp, cleartcp, pptp, calls you will see some utilization.
