Cisco m9100 MDS cpu state discrepencies

Hi.
I have weird issues with my m9100 MDS's cpu. After CISCOWorks complains that thoses equipement were peaking at 100% every minutes or so, I went on the equipements and try'd a few "show system ressources". Here is the result (remark the cpu states in bold);

It appear, sometime, for an unknown reason, CPU peaks to a weird % number (I thought a % couldn't get higher than 100).
Also, trying a "show process" (to get the running processes) command dosen't work. I am only able to "show processes"
Did someone experience same kind of discrepencies? I am running m9100-s2ek9-mz.4.1.1b.bin image.
Thank you.

Seen a lot of  incorrect CPU utilization values due to bug CSCte81951. Note the new spelling of the command to see the cpu history etc.
From bug info:
"show system resources" shows high cpu usage even when there is not much activity on the switch.
In the specific case reported the cpu util (user+kernel) was always 100%.
No workarounds. Use "show processes cpu history" or "show processes cpu" for
cpu util. Fixed in 4.2(4) and 5.0(1a).

  • ASR1002-ESP10 CPU Stats at 0%

    I am having trouble figuring out how to see my CPU usage on an ASR1002-ESP10 and I am convinced it is me doing something wrong...
    I used to have a 7204VXR and configured FASTCEF to offload from the CPU. On that router when I started running traffic I would simply run "show processes CPU" to get an idea of what my CPU on the router was.
    Now on the Cisco ASR1002 with ESP10 card I setup Distributed CEF which appeared to be the "new cool thing" that cisco implemented. Everything is working so well but I am confused because when I run "show processes cpu" on this bad boy it says 0% everytime.. Even while running very large loads.
    So now I am wondering how to know when I hit my limits as it appears the distributed CEF is handling my entire load without even hitting 1% on the CPU...
    One more example...
    We do SIP and with our old router would scale equally as we increased total SIP paths. Around 4k channels we would be at 90%.... Obviously this new router is 8.5 times more powerful in terms of Packets Per Second but it scares me a bit that the CPU may stay at 0% and then when we hit X amount of channels that it will pull from CPU.. Another words my fear is that we run 30k channels and its 0% CPU but when we go to 32K channels the CPU is at 100% because maybe that ESP card is full at 30k and then the last 2k channels is all hitting CPU...
    Maybe I did not explain it well but I guess the simple question is how do I monitor this since CPU is always 0%.

  • What is %IOWAIT of CPU states in TOP command output

    What is "% iowait" in CPU States in Solaris? See below output it shows 11.2 % of CPU was used for IO.
    Is CPU used in IO as well? If yes how?
    last pid: 15598; load averages: 3.66, 3.39, 3.07 18:33:27

    PID USERNAME THR PRI NICE SIZE RES STATE TIME CPU COMMAND

    The value of %iowait is relatively semi-meaningless these days and as a result we removed it from Solaris 10 onwards. The parameter is still displayed in certain commands but it will always be zero.

  • Mds-crash-state?

    i was updating my two ipods and i noticed something in the macintosh hd and it had a white file and it was labeled mds-crash-state. when i clicked it said there was no application to open it. when i tried to delete it, it required a password. what is this file?!?!!?!? it sounds horrible!

    This file appears if Spotlight crashes at some point; you don't need to keep it on your hard disk. You were asked for a password when you tried to delete it because the hard disk has a flag set which will cause non-root users to be asked for an administrator password if they try to delete something which they aren't the owner of from the disk's top level.

  • Confused about Activity Monitor CPU stats

    I have found at least one case where the CPU summary usage stats seem inconsistent with the per-process stats also posted.
    For example, I had noticed that under certain circumstances, the kernal_task was pegged at ~7.9% (only varying a few tenths of a percent) and yet the average "idle" CPU usage is consistently ~97 to ~98 percent (I would have expected ~92 to ~93 percent given that all but the kernel_task were pretty much idle during the observation period).
    Clearly, the summary averages are being calculated differently (over a different time scale???) than the line item process averages.
    This is not the pressing issue of the century .... still, I'd like to get a better idea of what these metrics mean.

    Let me guess ... if I've got 2 dual proc's it's 400% and 2 quad proc's it's 800% ????
    So the line item CPU stats are per processor, and the overall usage is calculated over 4 processors ?? (That roughly corresponds to seeing one task showing 8% loading ... but overall loading at 2% ... which is what I observed.)

  • Cisco recommendations for CPU, Memory, Buffers

    Hi, I am trying to define SNMP threholds within our customers network.
      Unfortunately, the hardware in the estate covers everything from 6500s, 7204s to 837's. I've been searching within Cisco website for CPU/Memory/Buffer recommendations but while I've found lots of useful information not exactly what I am looking for.
    I realise that the services, routing protocols, importance of each device will have a bearing on my thresholds but even if I had a starting point with a Cisco minimum recommendation document, it would help me.
    Can anyone point me in the right direction?
    Regards
    Mary O Driscoll

    You are correct that coming up with hard numbers really depends on the platform, traffic load, features, etc.  In general, CPU at 70% would be a minor alert, 80% a major alert, 90% a critical alert.  With buffers, at 65% (in use) is a minor alert, 70% is a major alert, and 75% is a critical alert (this data is actually used by the Embedded Resource Manager to do buffer memory reclamation in 12.4(6)T and higher).  With memory, 30% free is a minor alert, 25% is a major alert, and 15% is a critical alert.
    As for a document for this, I don't know of one.  These kind of general numbers are either used within IOS itself, or by our Device Fault Manager application to provide default thresholds.

    I am not sure what IOS version you are using but here's my recommendation:  
    1.  If you are running 12.2 then use 12.2(55)SE8; or
    2.  If you are running 15.X then use 15.0(2)SE4.
    Don't even bother using the others.

    Hi Rizwan,
    Here, as per observation, Software is unable to recover these error messages (As the HW Index and ErrAddress in these errors are common) or SUP Engine is having Hardware problem (Since the Errors are collected on Active SUP Engine only). We have to isolate this issue by below method.
    Remove the SUP & Reinsert it again / if you have spare SUP then replace Active SUP Engin
    If same errors observed, we need to upgrade the Image & if not then need to replace the SUP Engine.
    In our case, issue got resolved after removing and reinserting the SUP Engine.
    CPU was normal too.
    Additionally, you can enable Bootup level complete, so that HW issue of Active SUP can be tackled during Bootup only & then you can remove the Active SUP Engine.

  • CISCO IPS 4260 CPU USAGE 99%

    Hi guys
    I'm detecting something unusual on my CISCO IPS 4260. This device have 2 CPU's but only in one cpu is showing 99% of use, and the inspection load varies from 40 to 50, and sometimes 80, here's a screenshot of what I'm talking about.
    Where can I start to troubleshoot why is showing this values.?
    Regards.

    do you think is normal that the IPS signature with more hits is de SIGID 5575 (NBT NetBIOS Session Service Failed Login?
    After doing some research it seems to be normal for a windows enviroment.
    Here is the information I got
    Description
    When a client connects to a SMB server (WinNT, Win95, Samba, etc..) a TCP connection to port 139 is established. The client then provides the server with its NetBIOS name and the NetBIOS name it wishes to connect to. If the name does not exist on the server, the session setup attempt fails and an error message is sent to the client. This could be an indicator of an attack.
    Recommended Filter
    Exclude internal networks as sources.
    Benign Triggers
    The default alarm level for this is low because this happens during normal network activity within a Windows network. As an example, when mounting the C: drive from a Windows 95 system to a Windows NT system, numerous session setup failures can occur while browsing the file system.
    As you can see you could excluded to stop triggering that, this is an informational signature

  • Cisco ips 4270 cpu 100% utilization...

    hi folks i have cisco ips 4270 version 7.0(2) E3 when i try to access it through IDM its show the cpu utilization of cpu1=100% and cpu4=100% but cpu1 and cpu2 are varying can any one please tell me what will be the solution of this problem...
    when i try to go to the configuration then its give me the attached error..........document attached please check....

    Hi,
    Having 100% on some of your CPU is normal on the IPS platform.
    The device is using it's idle cycles to prepare for the handling of the incoming packets and to reduce the delay it will introduce on their path so it is expected to get this even when under low load.
    If you want to have a better idea of the capacity % of your IPS you are currently using, you should have a look at the Inspection Load value. Looking at the data you provided, you are around 25% at the moment.
    For the rdep timeout message, it seems to be a software issue. Looking closer at the picture you attached, we also see "Analysis Engine Status: Not Responding".
    It is a bit difficult to troubleshoot those on CSC so I would advise you to open a TAC case if you want to know the exact root cause.
    What I would advise is to upgrade to the latest 7(0) code which is I believe 7.0(5a)E4 since the issue is most then likely fixed in this version.
    If you are looking for a quick fix, a reboot of the IPS should clear this but the problem will most then likely come back later.

    Nicolas

    The normal operating temperature for this router is 0 - 40degC, this depends on the altitiude of your location. The data sheet for these routers is here http://www.cisco.com/c/en/us/products/collateral/routers/2900-series-integrated-services-routers-isr/data_sheet_c78_553896.html

    Hi,
    1) looking at the error message decoder
    The alarm generates the following output:-
    %IVR-3-LOW_CPU_RESOURCE: IVR: System experiencing high cpu utilization ([dec]/100). Call (callID=[dec]) is rejected.\n
    The system does not have enough CPU resources available to accept a new call.
    Recommended Action: Ensure that the call setup rate is within the supported capacity of this gateway.
    Related documents- No specific documents apply to this error message.
    2) Have a read at this link re High CPU - IP INPUT

  • CISCO SAN MDS: zone mebership changed from fcalias to simply PWWN

    I am not sure when it happened. It could be related to ISLing 2 switches together. But 99% of my zones which were fcalias based zones are now showing up without fcalias
    This is an example
    #show zone
    zone name X1 vsan 2
      pwwn 21:00:00:1b:32:94:ed:06
      pwwn 50:06:01:6a:44:60:0e:5c
    New zones are showing up OK like below
    zone name X2 vsan 2
      fcalias name a1 vsan 2
        pwwn 50:01:73:80:2f:c2:01:82
      fcalias name a2 vsan 2
        pwwn 50:01:73:80:2f:c2:01:72
    What happened?

    Hi,
    Notice the difference in the full zoning database and the active zoning database below.
    The full zoning database contains the fcalias'es and the active zoneset does not.
    When the copy command is issued, there is a warning.
    The best way to recover is to restore from your backups.
    Another alternative is to use Device-aliases instead, which does not have this limitation.
    MDS# show zoneset v 99
    zoneset name zs99 vsan 99
      zone name zone99 vsan 99
        fcalias name v99alias1 vsan 99
          pwwn 10:00:00:00:00:00:00:01
        fcalias name v99alias2 vsan 99
          pwwn 10:00:00:00:00:00:00:02
    MDS# show zoneset act v 99
    zoneset name zs99 vsan 99
      zone name zone99 vsan 99
        pwwn 10:00:00:00:00:00:00:01
        pwwn 10:00:00:00:00:00:00:02
    MDS# zone copy active-zoneset full-zoneset v 99
    WARNING: This command may overwrite common zones in the full zoneset. Do you want to continue? (y/n) [n]
    It overwrote the alias zoning with pwwn zoning.
    Regards,
    David
