CPU information/utilization

Hi,
Can anyone put me on the right path as to how I can determine cpu information, including cpu utilization? I'm not too familiar with all the java technologies available, so any suggestions or advice would be greatly appreciated!
TIA,
-Mike

I'm pretty sure there's no way to do this without using any native code. One of the big things about Java is that your applications run on a virtual machine and remain completely isolated from any architectual or operating system specific stuff on the actual computer your running on. Getting CPU utilization percentage would cross over this boundary, because the methods of getting CPU utilization can vary depending on the type of processor in the machine, and the operating system that is running. One thing you can do is get the amount of free memory available to the virtual machine by using the freeMemory() and totalMemory() methods of the Runtime class.
Check out the System and Runtime classes. The methods of those two classes are tied in very closely with the machine you are running on, and let you do a lot of OS-specific stuff (like make Win32 API calls to get the current CPU usage).

WLC 7.0.98.0 CPU high utilization

I could not find anything wrong with the show tech on WLC. Client complaints CPU high utilization. Please help!

Hi Andrew,
There are a couple of interesting things in the debug output you included, firstly there are some unsupported rates by the clients, in other words do you have some 802.11b clients trying to connect? Because I think you may have unsupported the 'b' rates on the controller. So either - ensure you have no 'b' clients or start supporting 'b' rates again (1, 2, 5.5, 11)
Secondly there some rogue AP containment going on, this can cause either your AP to have a high CPU, f there are multiple rogue APs being contained, or it may be that your own clients are being de-authenticated by another wireless network in the area - in other words, your network is under attack.

To get the windows CPU information

Hi, can anyone tell me that, how can i get the CPU information like
-how many processes are running on the machine?
-what are the applications running on the system, what are the status of these applications?
- What is the percentage of the CPU Usage?
i,e, the information we get when we press ctl+alt+del in the windows operating system.
How can i get this information of a machine by doing code in java?????????????
please help please help please help please help if anyone know.

hi, last day you replied my question about "How to
get the System information from a java code". You
told that we can do it in VB and then call the VB
code from java using JNI.
please reply me in more detatils about the process
regarding the call of VB code using JNI.
Please reply. I am in deep shit.Have you never heard about google? I entered "execute vb code from java" into google and got this and several other answers:

Historical CPU/Memory utilization data and xm top interpretation

Hi All,
Can we get historical CPU/Memory utilization data on domU server. xm top command give real-time data.
secondly, how to interpret xm top command output.

Does it implies that there are 2 virtual CPUs configured for guest(domain1), which at this moment 98.7% utilized. Doesn't it shows there is capacity problem?
In virtualization, are virtual CPUs dedicated to guests, or CPU cycles are available on demand. If this is the case, then one guest high utilization can slow down other guests as well.

How do I get CPU / memory utilization information via the API?

I can't seem to find anything in the iOS API that would give me information about CPU utilization (user, kernel, idle) and memory (free, pinned, idle, in use), but I see apps like System Activity Monitor in the app store that provide such information. Can anyone point me to the relevant part of the SDK?

This is a quection for the Developer forum.

No Video Playback & CPU/Memory Utilization

I just rendered an M2V out of Premiere Pro CS5 with Adobe Media Encoder. I used the widescreen progressive high quality preset. The M2V plays fine in VLC Media Player.
When I create a new project and import into Encore CS5, Encore goes nuts and sits on 50% CPU for a long while, while memory utilization by the process goes from 400MB - 1GB in about 8 seconds, and then drops suddenly back to 400MB and then repeats this a number of times before it stops. Then next time I click on almost anything, it does this again.
When I finally got the M2V in a timeline, it all looks good, but motion video does not play back. The Play button changes to a Pause icon but nothing plays.
This is a clean install of Windows 7 x64, all latest drivers, and I already tested my memory and it is all good.
Ideas?

•Have you gone to the vendor web site to check for a newer driver?
•For Windows, do NOT rely on Windows Update to have current driver information
•-you need to go direct to the vendor web site and check updates for yourself
•nVidia Driver Downloads http://www.nvidia.com/Download/index.aspx?lang=en-us
Be aware that while the latest driver is usually used, you MAY need to use an older driver

CPU,Temp utilization for a particular schema

Hi,
There is a requirement to get the CPU utilization at a schema level for a particular database.
Is this something we can get from AWR reports?
Is there any other way of getting these reports.
Regards,

AWR, yes
Try:
select a.username, count(*) "ON CPU", ratio_to_report(count(*)) over() ratio
from dba_users a, dba_hist_active_sess_history b
where a.user_id = b.user_id
and b.session_state = 'ON CPU'
and b.session_type = 'FOREGROUND' --comment out if needed
group by a.username
order by 2 desc;HTH

Need to retrieve memory and cpu information

level: Advanced
i m working on a cluster related software (not a business software, just a thesis work). i need to retrieve current memory and cpu usage info (i m using windows xp, i need the info what we get by pressing (alt+ctrl+del)). i need to use pure java. please tell me a better and easy way.

i know about JNI and i know Runtime.exec(), but theRight, then you also know what to search for on google.
problem is it would not be helpful for my program to
call taskmgr by Runtime.exec() and for using JNI i
need the native code in c or c++ to retrieve the cpu
and memory usage information. but i m not expert in c
or c++. Thats more search factors to add to the google search.
please help me somehow. if u have any reliable native
code then help me. the code should provide both cpu
and memory usage info instantly.Thats another requirement to add to that google search.
There may be free versions out ther, but you are going to have to do the leg work, nobody is going to do your work for you. You know about runtime.exec(), you know about JNI, now do a search.

SA540 CPU 100% Utilization AND VPN Failures

I am having regular trouble with my SA540 in that the VPN tunnels are failing. When I check the VPN tunnel I also find that the CPU utilization is listed at 100%.
Any suggestions?
Gregg

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

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.

Motion CPU/GPU utilization during render

I viewed with great interest the 90%+ CPU Activity Monitor while trying out the brand-new Adobe Media Encoder. Exciting utilization of technology to get stuff done.
I looked at that same CPU Activity Monitor while rendering in Motion, and saw all 8 cores on my machine working away, with nowhere near the utilization manifest in this newer app. Glad to see that there are those apps arriving that can harness nearly all the power of these incredible machines...
Perhaps there are preferences I've not chosen that will allow Motion to harness that power as well. I'm all ears!

lol.. http://discussions.apple.com/thread.jspa?messageID=7783196&#7783196
I wish there was an update allowing for CPU usage, being optional or something...

CPU,MEMORY UTILIZATION

hi,
What should be the desirable percentage of cpu and memory utilization

You must gather few stats related to your
-CPU utilization
-memory
-swap space and other system resources and maintain thm for your help so as to set thresholds for your system's optimal utilization and peakloads.
Generally on multiple CPU box its considered 90% CPU utilization for ~15-30 mins is area of consideration,though mometarily spikes are tolerable but should not exceed ~5 mins.This way you can sort out the issue related to CPU ,Memory etc resource utilization.
Hope this could provide you insights of the Utilization

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?

ADF Apps, CPU high utilization on OAS, how to find the cause of problem ?

Hi all,
We are running ADFBC application on OAS 10.1.3.3 on RH Linux ES 4. The database is Oracle 10g on RH Linux also.
Memory is 16 GB. 1 JVM.
Most of time I see (with linux "top" command) that CPU utilization on OAS is 99.9 %
And at the peak load (150 -200 users) user gets very slow that we have to restart the OC4J to the it normal again.
here is the setting in opmn.xml :
<data id="java-bin" value="/opt/oracle/OraHome_oc4j/jdk64/jdk1.5.0_17/bin/java"/>
<data id="java-options" value="-server -XX:CompileCommand=exclude,oracle/sql/NUMBER,toBytes
-ms3072M -mx3072M -XX:+AggressiveHeap -XX:MaxPermSize=1024M -XX:AppendRatio=3 -Djava.security.policy=$ORACLE_HOME/j2ee/ittas/config/java2.policy
-Djava.awt.headless=true -Dhttp.webdir.enable=false"/>
Heap Usage on EM, is between 2250 MB - 2850 MB.
How do I know what is the cause of that problem ? How can AD4J help to find the source of the problem ?
Thank you very much,
xtanto

xtanto,
Hi again...
Just a quick thought (I know it doesn't answer your question directly, but...) have you tried multiple JVM's? It's really quite easy to set up in OAS, and may possibly help you out. How many CPU's on the box?
We have an app (it gets such high concurrent usage during one period of the year), and we're running it on 3 JVM's on a single Linux box with either 2 or 4 (cannot recall) CPU's
