How to monitor cpu frequency change via inotify?

BIG EDIT:
See, this works:
shell 1:
#touch /tmp/hello
#inotifywait /tmp/hello
Setting up watches.
Watches established.
Shell2:
#echo hello >/tmp/hello
Shell1:
/tmp/hello MODIFY
This does not!
shell 1:
# inotifywait /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
Setting up watches.
Watches established.
Shell 2:
# cpupower frequency-set -g powersave
Setting cpu: 0
Setting cpu: 1
Gozer ~ # cpupower frequency-set -g performance
Setting cpu: 0
Setting cpu: 1
Shell 1 is still waiting... WHY?
Anybody could try to reproduce and or give me an hint?

  • How to monitor cpu frequency?

    Hi,
    I'm wondering if it's possible to see what frequency the cpu is using (this would be for an Intel based system - Macbook Pro).
    Is there some sort of widget that allows this (I'm not after the CPU usage %, just the frequency)?
    Or some CLI command or logfile?
    I read about the CLI command 'pmset', but I don't know if this works for intel-based machines.
    Also, it just seems to have a possibility to disable/enable the 'reduce' option.
    Many thanks,
    Sven

  • Does the iphone cpu frequency change when the cpu load is different?

    Does the iphone cpu frequency change when the cpu load is different, or it does not change, stay a fixed frequency? if it changes, how can i get the realtime cpu frequency?if anyone knows,please tell me, thank you so much!!!

    As a general, historical statement Tonefox is correct.  For certain particular cpus woodmeister is correct.  Cpus have historically been single frequency units, though over-clocking has been done for several years.  Doing so pushes the cpu beyond its guaranteed speed, but has tended to work since most cpus from quality vendors will actually operate at higher speeds.  The manufacturer just does not guarantee the results...remember the Pentium fiasco in the early years of that chip?  Today manufacturers are ceertifying particular product lines for over-clocking on a periodic basis.  And that is what dynamic clocking really is, over-clocking but not at a constant clock speed as has been done in the past.
    Much of the silicon on the market will function at higher clock rates, the only question is does the maker guarantee the accuracy and performance at those clock rates.

  • How to monitor CPU usage and performance on a Hyper-V server with several VM's

    I have a server that is running Windows 2008 64 bit Hyper-V, with 8 gigs of RAM and Intel Xeon X3440 @ 2.53 Ghz, which gives me 8 logical cores in the performance monitor on the host system.
    I have set up three Virtual Machines, all running Windows 2008 32 bit.
    Build server, running Team City
    Staging server
    SQL Server, running SQL Server 2005
    I have some troubles with the setup in that the host monitor remains responsive at all times, even though the VM's are seemingly working at 100% cpu and are very sluggish and unresponsive. (I have asked a separate question about that.)
    So the question here is: What is the best way to monitor how the physical CPU's are actually utilized? The reason I am asking is that I am being told that i cannot reliably use the task manager to monitor CPU usage in a VM.

    First, you have to remember that in Hyper-V that the "host" is called a parent partition and it really just like a virtualized guest with special permissions and roles. Just like any other child/guest, when you open up Task Manager, you can not see the CPU
    usage of the other children on the server.
    Ben Armstrong has a good explanation of this here:http://blogs.msdn.com/virtual_pc_guy/archive/2008/02/28/hyper-v-virtual-machine-cpu-usage-and-task-manager.aspx
    To summarize his post, you need to check three things to get an accurate picture of CPU utilization:
    View the CPU usage on each guest - this is available through Hyper-V Manager or Performance Monitor.
    CPU usage due to context switching - this is the perfmon counter called % Hypervisor Run Timeunder Hyper-V Hypervisor Virtual Processor
    Child partition worker process - vmwp.exe running on the parent partition (1 per child). This handles Hyper-V operations like saving
    state.

  • How to monitor the status change of pp order?

    I want to monitor all of the status change of PP order ,when the status change to DLV, system trigger a idoc to legacy system.
    I added some code in EXIT_SAPLCOBT_001, but I found this user exit only working in CO02, when I use MIGO or MB1C ... tcode to do some GR, the source code is not woking, that means I have to add the code to any entrance of status change????? anybody have some good idea? maybe I have to add a monitor to monitor the table jest ????

    Could you elaborate your requirement please?
    Anyways, the BP transaction display/change mode can be controlled through settings. Goto BP->Extras->Settings->Choose Display/Change/Setting last selected. May be in your system, the setting is 'Setting last selected'. That's why it's showing the last status display/change. If you want it to be display only, you can change the setting to display. But, the settings are user specific and any changes made will reflect for the specific user.

  • How to monitor CPU load/utilization

    Hi
    We have an application which is deployed in a jboss server on solaris/windows. We need to monitor the system load and if the load exceeds certain threshold value then the application has to send out a notification (warning).Is there any java API available for the same.
    We do not intend to use "ManagementFactory.getOperatingSystemMXBean().getSystemLoadAverage()". as this doesn't exactly show the CPU utilization.
    We use jdk1.6.
    Any help would be appreciated

    load average is related to the queue length(prstat), where as CPU utilization is actual percentage of cpu utilization by the all the processes (vmstat).
    In the wiki page it was mentioned that load average would consider even the process in waiting state.
    [http://en.wikipedia.org/wiki/Load_(computing]
    Correct me if my understanding is wrong
    - Is there any third party tool which can be used for this purpose?

  • How to monitor user password changes for users in a database.

    hi All,
    can someone please help me.
    I need to audit the user password changes in a database. Ive check the auditing but audit " alter user " doesnt audit the changes in password and ive also checked the select * from sys.user_history$; view but didnt find anything useful. So is there a way to trace who changed the password and when ?
    Thanks for the help.

    You need something along the lines of http://www.morganslibrary.org/reference/ddl_trigger.html
    or you need to disallow ALTER USER to everyone and write your own PL/SQL and instrument logging the changes.

  • How to monitor bandwidth on Catalyst via SNMP?

    I've got c3750g with 12.2(55)SE.
    When I try ifSpeed (1.3.6.1.2.1.2.2.1.5), i've got 1 peak 999999999 and then only 0. Polling is 1 second.
    When I try ifHighSpeed (1.3.6.1.2.1.31.1.1.1.15), I've 0 also.
    When I try ifInOctets from snmp-v2 MIB (1.3.6.1.2.1.2.2.1.10), I've got results, but since it summary - my software cannot do calculations and I cant get instant interface bandwidth.
    Is there any solutions for catalyst?

    Hi,
    Are you saying ifSpeed. is changing value from one poll to the next? What kind of interface is it? Sounds like a bug, or an error in polling. Please post the snmpwalk of ifDescr, ifType, and ifSpeed.
    For the ifHighSpeed issue, from the IF-MIB entry about that object: "For a sub-layer which has no concept of                bandwidth, this object should be zero." Are you polling ifHighSpeed on a sub-layer interface?
    Bandwidth utilization is always calculated by taking multiple readings of in or out counters. There will not be a separate counter kept in our snmp agent, when separate values already exist and can be calculated. Thus, since you can use ifSpeed and poll ifInOctets to get the delta, and then calculate the result, our snmp agent will not contain the utilization number.
    If you want a graph of bandwidth utilization over time, I would suggest obtaining MRTG. It is available free of charge over the web, just search for MRTG download.
    Hope that helps,
    Curtis

    No, I just want to save battery power. I don't want the CPU to be clocked as high when I'm on battery. I would set the CPUFreq governor to ondemand, but when I issue sudo cpupower frequency-set -g ondemand, I get:
    Setting cpu: 0
    Error setting new values. Common errors:
    - Do you have proper administration rights? (super-user?)
    - Is the governor you requested available and modprobed?
    - Trying to set an invalid policy?
    - Trying to set a specific frequency, but userspace governor is not available,
    for example because of hardware which cannot be set to a specific frequency
    or because the userspace governor isn't loaded?
    The output of ls /lib/modules/$(uname -r)/kernel/drivers/cpufreq/ is:
    acpi-cpufreq.ko.gz cpufreq_stats.ko.gz powernow-k8.ko.gz
    amd_freq_sensitivity.ko.gz cpufreq_userspace.ko.gz speedstep-lib.ko.gz
    cpufreq_conservative.ko.gz p4-clockmod.ko.gz
    cpufreq_powersave.ko.gz pcc-cpufreq.ko.gz
    Doing modprobe cpufreq_ondemand and trying again does nothing.
    So, since I can't use the ondemand governor and then raise the threshold, I need to limit the CPU frequency.
    Thanks.

  • [solved] What is constantly changing my CPU frequency?

    Hi there,
    I set /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor to userspace but still something is changing my frequency automatically:
    [root@thinkpad orschiro]# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
    1866000
    [root@thinkpad orschiro]# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
    800000
    Suddenly the frequency changes from 1866000 to 800000. Why is it not enough to set the govenor to userspace and what is causing the frequency to change?
    I am running a Thinkpad X200T with Gnome 3.8.
    Thanks!

    If you check the documentation for the CPUfreq governors you’ll see that performance is not the only governor that will not change the frequency.
    Edit: also, have you checked https://wiki.archlinux.org/index.php/CP … limitation and http://www.thinkwiki.org/wiki/Problem_w … cy_scaling ?

  • How to make GNOME power management auto scale cpu frequency?

    Hello everyone, I installed Archlinux on my new Toshiba U400/H00, everything works nicely, however, I need to manually scale cpu frequency when on AC/Battery, is there a way to make Gnome automatically scale it?
    Thanks a lot!

    Maybe just go down to acpid level and do it independently of DE devs idiosyncrasies?
    For me, the following code in /etc/acpi/handler.sh does the job:
    ac_adapter)
    case "$2" in
    ACAD)
    case "$4" in
    00000000)
    echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
    echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
    00000001)
    echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
    echo 499 > /proc/sys/vm/dirty_writeback_centisecs
    esac
    *) logger "ACPI action undefined: $2" ;;
    esac
    I believe the original code there tried to set fixed clockspeeds for these situations, but I find changing governor much more flexible.
    Edit: there were some ACPI-related bugs during 2.6.26-27 development cycle, it may happen that you won't get any ACPI events playing with power source. 2.6.28 cured all ACPI problems for me, but YMMV.

  • [solved] GNOME cpu frequency scaling monitor applet doesn't work

    Hello,
    i have installed everything successfully (i come from fedora), but now i have a problem
    I want to add the cpu frequency scaling monitor applet to the panel, but i can't see it. When i rightclick on this place, the submenu with settings and so on is displayed, and i can choose the other cpu1 instead of cpu0, then the applet appears. But the applet shows 0 Mhz and i can't choose a frequency or something.
    I start GNOME with xinit and have added exec ck-launch-session gnome-session to ~/.xinitrc, because shutdown wasn't displayed at the beginning and automouting permission problems.
    What's the problem?
    Edit: My system is a netbook with intel atom cpu
    Last edited by scenox (2010-07-19 18:11:59)

    the problem is that the modules are not loaded automatically for cpu scaling and you have to explicity add them into rc.conf, MODULES array.
    MODULES=(...acpi-cpufreq cpufreq_ondemand...)

  • Lower the CPU frequency, permanently....how to do?

    I just want to know, if its possible, how to lower the frequency of my Athlon64 3000+ permanently to like 1GHz or so, since its more then enough for my server. I'm not 100% sure, but I think all Cool n' Quiet does is lowering the clock, not mess with voltages and stuff, and apparently that is enough to save like 10W or so powerconsumption. Would be nice
    Thanks in advance

    I have to scale down permanently my laptops cpu max_freq because the speedstepping modules are overclocking my cpu.
    cactus wrote:cat something like /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies to get the avail frequencies, and set it with echo statements to /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed (or whatever) in rc.sysinit.
    As cactus said, with
    cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
    you get the available freqs of your CPU.
    for example:
    1600000 1400000 1200000 800000 600000
    One of this values is stored in  /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
    I have this line in /etc/rc.local to set the max_freq on boot.
    echo 1400000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
    P.S.
    I don't know if the pathes are exactly the same on all systems. If the files don't exist on you system check if the Speedstepping kernel modules for your CPU are loaded....
