LINUXHEALTH CPU Load wrong

gnulptgnulpt
edited September 2009 in Monitoring Software v12 and lower
Hi,



I am currently trying the evaluation version.



I have installed the LINUXHEALTH agent as described in the Wiki using the server.c file from the installed version.



Compiled the file and run it as instructed.



I am able to setup a rule to monitor LINUXHEALTH.

The monitor shows up but unfortunately the CPU load is stuck at 50% even with the server idling.



Disk capacity seems to be fine.



Do I need to modify something in the server.c ?

I am running RedHat Linux.



Thanks



Klaus König

    When you telnet to the Linux server on port 5555, what data is returned?



    Which version of the software are you running?
  • gnulptgnulpt
    I am running 8.0 RC1, downloaded from your website. The server.c is the one included in the Add-on directory of the installed version.



    I do not know how to add the log file to this post, so I just copied the CPU part in here...



    --- CPU states ---

    Cpu(s): 0.1%us, 0.1%sy, 0.0%ni, 99.4%id, 0.4%wa, 0.0%hi, 0.0%si, 0.0%st

    Cpu(s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st





    BTW my system has Dual Quad Core Xeon processors (2 Cpus).



    Thanks for your help!

    When you click on test settings in the web interface of the software, then what is returned?



    It seems that CPU info is returned correctly. Based upon above CPU usage is 0.6%
  • gnulptgnulpt
    Here is the result of the test...

    Test-Einstellungen

    ----------------------------------------------------------------------

    Der Check wurde ausgeführt.





    Status: OK

    Zurückgegebener Wert: PING 3ms - 50.4 % CPU usage - 93 % Free memory - 57 % free on sda2 - 96 % free on sda4 - 93 % free on sda1 - 100 % free on tmpfs -

    ----



    So CPU usage is somehow wrong...



    I got a bit adventerout and changed the port from 5555 to 5554 and voila, CPU usage is more sensible now....



    Guess that was it.



    Thanks for your patience!

    sorry.... not quite solved...



    the CPU reading is still inconsistant...



    sometimes it seems right, sometimes it is wrong...



    Any ideas?

    When you click on test settings do you always get that value of around 50%



    It seems to get values from the agent. The question now is, is it misreading the values returned from the agent, or is the agent always returning that. Invoking the agent shouldn't result in a 50% CPU usage.



    Assuming you are running release 8, download following test build of the monitoring_thread2.exe which will create when running a file called linuxhealthdebug.log

    http://files.serverscheck.net/fixes/gnulpt.zip



    Once downloaded, stop the monitoring service. Rename the current monitoring_thread2.exe to something else. Put the downloaded one in the main serverscheck folder and restart the services.



    Let it run for a few minutes until some data is in there and then reply with the output produced.


  • gnulptgnulpt
    Thanks for the quick response!



    Yes, I always get a value around 50%.



    Did the change as requested and ran the linuxhealth at port 5555.



    Here is the result from the log file...



    Looks like it is using the idle % and it might not handle the second cpu correctly...



    Maybe it would also be cool to have two CPU meters when 2 CPUs are present....

    Thank you for this very useful feedback. Based on what I see, it seems that the issue is the 100% CPU idle on the second CPU.



    I have passed it on to development and I'll update you later today with feedback I have.

    Please repeat the download. An updated version has been posted with now 2 files in there.

    I have installed the two files and the result looks better...



    Here are two log entries:

    Guess that seems to be right?!?!



    The log file is still outputted by the process, can I cure this by using the original monitoring_thread2 or do you have to send me a new one without the logging?



    Still I think it would be useful to have a little cpu dial for each cpu of the machine. Then you could see if one cpu is running 100% while the other is idling. Just one dial would tell you you are running at 50% load not reflecting the situation....



    Oh, one last little bug...

    on the main GUI, in the top left section where it tells you since when the thing is running, there is a line that tells you when it was last updated. On the time readout, it is swallowing the leading 0 of the minutes.

    So rather telling you it was run at e.g. 15:09 it reads 15:9

    At 15:10 everything is fine again > readout 15:10



    Rgds.
