Scheduling monitoring of Total CPU Utilization

Hi,
Looks like the question has been asked all over the internet but I can't find a good answer to it and whatever that would look like a start of an answer is for 2007... So here is my question, which is for Operation Manager 2012 R2
I have a bunch of servers with the CPU going over the roof at night. These are known and normal since they run CPU heavy tasks "Only at night"
Therefore I still want to monitor the CPU for those servers, but only trigger an alert when it happens during business hours.
How can I achieve this ? Please help !
Cheers :)

Hi nocrack
As bobgreen states, you need to create a monitor with a scheduler. This cannot be done from the Operations Console.
Check this blog for guidance:

No Server Name displyed in mail notification Alert generated by "total CPU Utilization Percentage is too high" Monitor

Hello Everyone,
I need your assisstance in one of the issues with Mail Notification Alert generated by SCOM.
Mail notification received as below:
Alert: Total CPU Utilization Percentage is too high
Severity: 2
ServerName:Microsoft Windows Server 2008 R2 Standard - The threshold for the Processor\% Processor Time\_Total performance counter has been exceeded. The values that exceeded the threshold are: 97.091921488444015% CPU and a processor queue length of 16.
Last modified by: System
The Alert was generated by "Total CPU Utilization Percentage"
But the problem with the above mail notification is it doesn't mentions about the affected server. So I would like to know how to tweak the monitors to provide the server name into it.
Thanks & Regards,
VROAN

Total cpu utilization percentage diagnostic removed from Windows 2008 MP?

SCOM 2012 SP1 environment running the Windows Server 2008 Operating System Management Pack, version 6.0.7026.0
http://www.microsoft.com/en-us/download/details.aspx?id=9296
We had a server that had high CPU utilization. We were able to figure out what process was causing the high CPU using some remote commands, but I am used to seeing this in the health explorer state change events view.
I looked into health explorer but there is no data.
http://i.imgur.com/eArmCM2.jpg
I then notice that in this MP, there are 2 CPU monitors
http://i.imgur.com/I9eBN4G.jpg
The first monitor shown is disabled by default, but it is this monitor that contains the diagnostic to list the top CPU consuming processes
http://i.imgur.com/tLgq9at.jpg
The CPU monitor that is enabled by default has no diagnostic tasks associated to it
http://i.imgur.com/AKAKOP9.jpg
While I have the ability to create my own diagnostic task, I would rather not, as it requires me to enter my own command or script.
I liked the fact that the CPU monitor would list the top consuming processes, as this was useful troubleshooting information.
Does anyone know why this diagnostic is not included in the new version of this monitor? I cannot find any information in the release notes.
Is there any reason I should think twice about disabling the default monitor, and setting an override to enable to “legacy” monitor that has the diagnostic task built in?

I can confirm that the other OS versions have the single CPU monitor with diagnostics set to run by default. For Windows Server 2008 R2 I have created a sample management pack which enables this functionality which is available at:

Total CPU Utilization Percentage - Windows Server 2012 Operating System

Hi All
I had gone through all the articles and agree with posts submitted, but do we have any KPI stating - ProcessorQueueLength actually tied to the number of logical cpu's.
As Jonathan stated in one of the forums
ProcessorQueueLength actually needs to exceed Processor Queue Length Threshold * Number Of Processors. Where do we find this and how to validate.
We had an issue of CPU been high almost 99% for hours, but never alerted. Any kind of pointers will be helpful, especially supporting statement like Processor Queue Length Threshold is tied up with number of logical CPU's.

Hi
you can create monitoring for performance counter for below counter
Object :System
Counter: Processor Queue Length.

Total CPU Percentage Utilization on MM

I have a process that runs every weekend that uses high CPU thus triggers "Total CPU Utilization Percentage is too high". Therefore I just want to put the CPU object in MM.
How do I do that?
I have look at get-monitoringclass & get-monitoringobject but couldn't figure out how to get processor object.
Please help.
Thanks

I suggest you override the Monitor to change a higher value for CPU usage.

Hello Amit,
this is obviously an internal process consuming all the CPU power, as Jamie already pointed out restarting the appliance may fix the problem, however before doing that you could open a support request have customer support look into that, to make sure not to whipe out any traces. You might also check the following things:
GUI: Monitor->System Capacity->Incoming Mail   Is the traffic or the number of concurrent connections always high? In this case there might be a capacity problem
CLI: status detail      Are there a lot of messages in the quarantine (several 10.000)? Lots of active recipients? May indicate a problem with the internal database or reporting.
A stuck database or workque process would go away after a reboot, a capacity problem, however, won't.

Airport Process utilizing high CPU utilization

I currently have a 13 inch MacBook Pro i7 (2012 version). Recently I upgraded to Mavericks. After using the computer for a day after the upgrade, I began to notice it becoming very hot and the fans running very high. Looking at the running processes i noticed that a process called "airport" was running and utilizing high CPU times causing the heating up and fans running. Once I stopped this process, the laptop went back to operating at normal levels.
Unfortunately this issue began to come back several times....the "airport" process starting at any time and utilizing high CPU utilization....again only by killing this process fixed this issue.
After seeing this behavior over several days, I decised to wipe the drive and install a clean copy of Mavericks in the computer. Thought here was that possibly something did not carry over correctly from the upgrade from Mountain Lion to Mavericks. Unfortunely this did not correct the issue with the "airport" process as it still is continiung to launch at any time and spike the processor until I manually kill the process.
I do not recall this issue occuring while running Mountain Lion so it seems to be specific to Mavericks at this point.
I was hoping to hear if any other have experienced this type of issues while running Mavericks.

You should be able to find the information you are looking for from the default Total CPU Utilization Percentage monitor. This monitor has a built in diagnostic task that will kick off when an alert is triggered to list the top cpu consuming processes.
To find which processes were causing CPU to spike, simply review the State Change Events history in health explorer for the machine that was affected, for the Total CPU Utilization Percentage monitor. I have modified my second screen shot
to remove machine names, but you should get the idea. If a cpu monitor went from green to red, it will run the diagnostic task and list the process information and cpu usage at the time of the alert under state change events.

Increased CPU utilization on Sup1A after upgrade

Hello,
I recently upgraded a 6009 with Supervisor 1A from CatOS 7.6(5) to 8.4(4). Baseline total CPU utilization before the upgrade was about 12%, post upgrade it sits at about 30%.
We have several similar switches throughout our network that we intend to upgrade as well, so are treating this one box as a testbed. We will soon deploy IP telephones to every desk in our network, and want to determine if this higher baseline utilization will be problematic for us.
Considering voice, should we be concerned about this? Will any changes due to voice deployment such as many trunks, QoS, etc. cause a significant jump in CPU that might put our baseline even higher?
Will the higher baseline CPU utilization affect switch performance? I know most forwarding functions do not depend upon the CPU, and are switched via ASIC.
thanks for the help,
Brad

The IDLE_Tasks process on which you are seeing a slightly higher CPU is actually an enhancement that collects information more effectively on crashinfo files (files generated when there is a crash on the box). This enhancement went into 8.3(x) and 8.4(x)
In the past "IDLE_tasks" processing was not counted and therefore belong to the "kernel and IDLE" process (which as you can see in the show proc cpu) accounts the amount of cpu not being used.
If you are upgrading other 6500's with Sup1a's make sure they all have 128MB DRAM just like this one has.

When ACD 30" monitor gets hot, kernel_task utilizes all CPU on Mac Book Air

I've been having a problem with my system slowing down due to the system "kernel_task" taking over all available CPU (up to 150% of a CPU on my dual core Mac Book Air). I've figured out some of the parameters of the problem, and it seems related to having the Air hooked up to an external monitor:
1) It seems to only happen when the Air is attached to an external monitor, which in my case is a 30" Cinema Display (which is through a Mini DisplayPort to Dual-Link DVI Adapter -- not sure if this is relevant)
2) It only happens when the monitor itself is physically warm to the touch (actually the back gets quite hot).
3) When the kernel_task takes over, and I unplug the Air from the DVI Adapter, kernel_task usually settles down (to 5 - 10% CPU utilization) within 30 - 60 seconds
4) If I plug the Air back into the DVI adapter at this point (while the monitor is still warm), kernel_task CPU utilization immediately jumps up to 130 - 150%.
5) If I wait until the monitor is cool before plugging the Air back into the DVI adapter, kernel_task stays in the normal 2 - 10% CPU utilization range for 30 - 90 minutes and the process starts all over again (at this point the monitor is usually quite warm / hot again)
Rebooting doesn't seem to help (if the monitor is hot, kernel_task starts hogging the CPU right after booting up).
Has anyone experienced a similar problem? Any thoughts about possible remedies, or ways to further isolate the problem?
I appreciate your reading this somewhat bizarre tale of woe.
Thanks,
Marc

After upgrading to 10.5.7 this week my MacBook Air goes into kernel_task spin-mode within minutes even when the machine is idle. There are many discussions about this, the longest of which is here: http://discussions.apple.com/thread.jspa?messageID=9458471&#9458471

Monitoring IP Gateway Activity hangs workstation and rise Servers CPU utilization 100%

Hi..
I have nw5.1 sp6 and BM 3.7 sp3 with last patches..installed with C.
Johnson's BM Book.
used services/proxies HTTP, FTP ,Generic TCP and Socks
Only one acces rule with indexed logging for denyed URL-s..
all works well except socks gateway sometimes. Sometimes, sometimes with no
reason, if you look real time activity of IP Gateway
(Nwadmin-tools-Bordermanager-IP Gateway) workstation hangs and server CPU
utilization rise to 100%. and only way reboot workstation and reload
proxy.nlm on server..
By the way the same is for Proxy cache monitor...
is any ideas ?
Thanks,
Lab.

May be.. Actually, i have pervasive upgraded to sp4 + postfixes
for other reasons and have some bti.cfg settings changed..
Thanks, i will look in this way..

MARS Monitoring PIX CPU Utilization

Is there a way that I can get my MARS box to watch for a user defined CPU utilization on my PIX 5x5? There is an event (1211003) that is defined as CPU utilization of 100%, but I'd like one for 40%. Is that even possible?

Probably not [using that event type anyway]. That event type directly corresponds to a syslog message from the pix saying the CPU utilization was >100% for some period of time.
see:
http://www.cisco.com/en/US/products/sw/secursw/ps2120/products_system_message_guide_chapter09186a008051a0cd.html#wp1053791
I'm not sure if there's a syslog message you can use for that. Are you using SNMP to the PIX and do you have monitor resource usage enabled? We don't use PIX, but I suspect this might do what you want. Surely there's someone on the forum using the PIX that knows the answer to this?

Performance degrading CPU utilization 100%

Hello,
RHEL 4
Oracle 10.2.0.4
Attached to a DAS (partition is 91% full) RAID 5
Over the past few weeks my production database performance has majorly degraded. I have not made any application, OS, or database changes (I was on vacation!). I have started troubleshooting, but need some more tips as to what else I can check.
My users run a query against the database, and for a table with only 40,000 rows, it will take about 2 minutes before the results return. For a table with 12 million records, it takes about 10 minutes or more for the query to complete. If I run a script that counts/displays a total record count for each table in the database as well as a total count of all records in the database (~15,000,000 records total), the script either takes about 45 minutes to complete or sometimes it just never completes. The Linux partition on my DAS is currently 91% full. I do not have Flashback or auditing enabled.
These are some things I tried/observed:
I shut down all applications/servers/connections to the database and then restarted the database. After starting the database, I monitored the DAS interface, and the CPU utilization spiked to 100% and never goes down, even with no users/application trying to connect to the database. The alert.log file contains these errors:
ORA-00603: ORACLE server session terminated by fatal error
ORA-00600: internal error code arguments: [ttcdrv-recursivecall]
ORA-03135: connection lost contact
ORA-06512: at "CTXSYS.SYNCRN", line 1
The database still starts, but the performance is bad. From the error above and after checking performance in EM, I see there are a lot of sync index jobs running by each of the schemas and the db sequential file read is high. There is a job to resync the indexes every 5 minutes. I am going to try disabling these jobs tihs afternoon to see what happens with the CPU utilization. If it helps, I will try adjusting the job from running every 5 minutes to something like every 30 minutes. Is there a way to defrag the CONTEXT indexes? REBUILD?
I'm not sure if I am running down the right path or not. Does anyone have any other suggestions as to what I can check? My SGA_TARGET is currently set to 880M and the SGA_MAX_SIZE is 2032M. Would it also help for me to increase the SGA_TARGET to the SGA_MAX_SIZE; thus increasing the amount of space allocated to the buffer cache? I have ASMM enabled and currently this is what is allocated:
Shared Pool = 18.2%
Buffer Cache = 61.8%
Large Pool = 16.4%
Java Pool = 1.8%
Other = 1.8%
I also ran ADDM and these were the results of my Performance Analysis:
34.7% The throughput of the I/O subsystem was significantly lower than expected (when I clicked on this it said to either implement ASM or stripe using SAME methodology...we are already using RAID5)
31% SQL statements consuming significant database time were found (I cannot make application code changes, and my database consists entirely of INSERT statements...there are never any deletes or updates. I see that the updates that are being made were by the index resyncing job to the various DR$ tables)
18% Individual database segments responsible for significant user I/O wait were found
15.9% Individual SQL statements responsible for significant user I/O wait were found
8.4% PL/SQL execution consumed significant database time
I also recently ran a SHRINK on all possible tablespace as recommended in EM, but that did not seem to help either.
Please let me know if I can provide any other pertinent information to solve the poor I/O problem. I am leaning toward thinking it has to do with the index sync job stepping on itself...the job cannot complete in 5 minutes before it tries to kick off again...but I could be completely wrong! What else can I check to figure out why I have 100% CPU utilization, with no users/applications connected? Thank you!
Mimi
Edited by: Mimi Miami on Jul 25, 2009 10:22 AM

Tables/Indexes last analyzed today.
I figured out that it was the Oracle Text indexes synching to frequently that was causing the problem. I disabled all the jobs that kicked off those indexes and my CPU utilization dropped to almost 0%. I will work on tuning the interval/re-enabling the indexes for my dynamic datasources.
Thank you for everyone's suggestions!

EEM applet that triggers on high CPU utilization

Hi Folks,
I am trying to create an eem applet which triggers on high cpu utilization (detected by erm).   The applet should then tftp the output from "show proc cpu sorted" to a tftp server.
I am trying to configure this on a 1841 running 124-24.T3 code
This is my config:
resource policy
policy HighGlobalCPU global
   system
    cpu total
     critical rising 5 falling 2 interval 10
    cpu process
     critical rising 5 falling 2 interval 10
! I'm not sure whether it is correct to monitor 'cpu total' or 'cpu process'.   The rising thresholds are deliberately low to maker testing easier
event manager applet ReportHighCPU
event resource policy "HighGlobalCPU"
action 1.0 cli command "show process cpu sorted 5sec | redirect tftp://192.168.1.1/highCPU$_resource_time_sent.txt"
action 2.0 syslog priority debugging msg "high cpu event detected, output tftp sent"
The problem is that I can't seem to trigger the applet.    I have generated enough traffic to push the cpu utilization to over 30% (according to 'show proc cpu'), but the applet does not appear to trigger (no syslog messages appear, and my syslog server does not receive anything).
If anyone can tell me what I've done wrong here I would be very grateful!
Thanks,
Darragh

I am just replying off the top of my head but I believe you
need to also add to your conf the line
user global HighGlobalCPU

AHCI cpu utilization skyrockets

This issue is a bit new to me--have done RAID and IDE setups for decades, but thought I'd tinker with AHCI. Motherboard is MSI 970a-G46. Enabling and disabling AHCI with an established Win7x64 installation is not a problem for me.
Problem is that after enabling AHCI properly, cpu usage soars to 25%-30%+ with the Windows AHCI drivers, and jumps to as high as 40% with the latest AMD chipset drivers. OK--this is what HD Tach reports, anyway. IDE settings for the same drives measure 1-2% cpu utilization. According to HD Tach, too, the performance of AHCI & IDE is identical. Ergo: I see no advantage for my client system running in AHCI and will return to IDE.
Agree--disagree? Suggestions? Thanks.

Quote from: Panther57 on 30-June-12, 01:01:20
This is an interesting post... With my new build I was set Raid0 / IDE. I had an unhappy line in device manager and changed to AHCI. Then it downloaded the driver.
I have not seen a jump in CPU usage. But I also have not been watching it like a hawk. Hmmm
I am going to watch my AMD System Monitor for results. In a post of mine..earlier.. I was told, and did some tests of AHCI vs: IDE. I ran IDE on my other PC (listed below, HTPC) and am now AHCI on my main 990FXA-GD80. The difference between the 2 ways tested on my 790FX actually did show an advantage IDE, using Bench32.
Not a huge advantage.. but a little over AHCI. I don't know if the difference is really worth much inspection.
I am looking forward to the results you get WaltC
Thanks, Panther57...;) My "results" are really more of an opinion, but ...
Right now I'm not really sure what hard drive benchmark I should be using or trusting!...;) HD Tach's last release in 2004 is now confirmed on the company's site as the last version of the bench it will make--as it is, I have to set the compatibility tab for WinXP just to run the darn thing in Win7x64! But...I installed the free version of HD Tune (and the 15-day trial for the "Pro" version of the program, too), and the results are very similar--except that HD Tune seems to be measuring my burst speeds incorrectly: HD Tach consistently puts them north of 200mb/s; HD Tune, well south of 200mb/s. (A strike against HD Tune--the free version does not measure cpu dependency--grrr-r-r-r. You have to pay for the "Pro" version to see that particular number, or install the Pro trial version which reveals those numbers for 15 days.)
OK, between the two benchmarks, and after several tests, cpu utilization seems high *both* in IDE and in AHCI modes. Like you, it has been quite awhile since I actually *looked* at cpu utilization of any kind for hard drives. I guess I wasn't prepared to see how cpu dependent things have become again. Certainly, we are nowhere near the point of decades ago when cpu utilization approached 100% and our programs would literally freeze while loading from the IDE disk, until the load was finished. The "good old days," right? NOT, hardly...;) I suppose, though, that with multicore cpus being the rule these days instead of the exception, cpu dependency is just not as big a deal as it was in the "old days" when we dealt with single-core cpus exclusively and searching an IDE drive could literally stop the whole show.
Again, when running these read tests to see the degree of cpu utilization, I found that while the tests were all uniform and basically just repeats of each other, done a couple of dozen times, the results for cpu utilization in each test were *all over the map*--from 0% to 40% cpu dependency! And the same was true whether I was testing in IDE mode or AHCI mode. That was kind of surprising--and yet, it still leaves open the question of how accurate and reliable the two HD benchmarks that I used actually are. Besides that, I did find a direct correlation between the size of the files being moved/copied and the degree of cpu dependency--the smaller the files copied and moved the higher the cpu involvement--the larger the files, the lower the cpu overhead in copying and moving, etc. Much as we'd expect.
So after all was said and done--it does seem to me that AHCI is actually more of a performer than IDE, albeit not by much. I think maybe it demands a tad less cpu dependency, too, which is another mark in its favor. In one group of tests I ran on a single drive (I also tested a pair of Windows-spanned hard drives in RAID 0 (software RAID) in AHCI and in IDE mode, just for the heck of it...;)), I found the *average* read speed of the AHCI drive some ~15mb/s faster than the same drive tested in IDE. That was with HD Tune tests. But as I've stated, how reliable or accurate are these benchmarks? Heh...;) Anybody's guess, I suppose.
My take in general on the subject (for anyone interested) is that going to AHCI won't hurt if a person decides to go that route, but it also won't help that much, either. You definitely can easily and very quickly move from an installed Win7 IDE installation to an AHCI installation, no problem (some sources swear it can't be done without a reformat and a reinstall--just not true! They just haven't discovered how easy and simple it is to move from IDE to AHCI and back again.) Current cpu dependencies whether in AHCI or in IDE surprise me they seem so high. However, the last time I paid close attention to such numbers was back when I ran a single-core cpu, and back then cpu dependency numbers for a hard drive meant quite a lot. Today's cpus have both the raw computational power and the number of cores to take that particular concern and put it on its ear, with a large grain of salt!...;)
I have three drives total at current:
Boot drive:
ST332062 OAS Sata, boot drive
then,
(2) ST350041 8AS Satas, spanned in software RAID 0, making two ~500GB RAID 0 partitions.
Total disk space ~1.32 terabytes, all drives including RAID 0 partitions running in AHCI mode. (Software RAID is just as happy with IDE, btw.)
My Friday "project" is complete...:] Hope I haven't confused anyone more than myself...;)
