NI HyperTrend Control raises the CPU usage of NI Citadel DB and freezes it.
When a VI uses NI HyperTrend Control to fetch data from NI Citadel DB, the CPU usage of citadel is raised up to 10% and stops working.
I don't know what "stops working" means since my coworker told me so.
How can the control be prevented from freezing citadel?

Can you run the Hyper Trend control without linking it to a particular trace?
Can you use the Hyper Trend control without starting your VI?
Best,
1) Does the Trace VIEW in MAX work?
yes with 3 signals(traces?)
2) What version of LabVIEW are you running?
9.0 SP1
3) Can you run the Hyper Trend control without linking it to a particular trace?
yes
4) Can you use the Hyper Trend control without starting your VI?
yes
5) And he has another question.
Please refer to the attached image.
For now, if he wants to put Va/Vb/Vc in Y axis of a hyper trend control, he has to do it in the front panel.
He wants to put it in Y-axis via a property node in the block diagram.
Is it possible?

Where is the cpu usage monitor in LPX?
Hi everyone,
Perhaps I missed something, but I don't find the cpu usage monitor in LPX. Anyone?Hey there you need to customise (change mode) the Control Bar and Display by right clicking on the icon on the far left of the LCD display.
If you choose Custom you can select the CPU and HD usage meters in the customise drop down menu when you right click in the display .
hope this helps. -
it has been only about a month that i bought my macbook pro 15 but it is heating up really fast on the left side even when the cpu usage is only 10%...i'm worried if this is a problem of the hardware?
The way something "feels" is very subjective. We would need to know your actual temps. You can install the free iStat Pro widget which is available as a download directly from Apple:
http://www.apple.com/downloads/dashboard/status/istatpro.html
Let us know what CPU temps you're seeing at the time you feel your machine is hot. As you indicated your CPU usage was only 10%, that would imply that you already know that heavy CPU usage would be one cause for your machine to be running on the warm side... but that doesn't seem to be the cause here. -
Methods to reduce the CPU Usage for painting the image
Hi,
I have developed an application to view images from an IP camera. By this I can simualtaneously view images from about 25 cameras. The problem is that the CPU Usage increases as the no of player increases. My Player is JPanel. which continuously paints the images from camera. The method 'paintImage' is called from another thread's run method. This thread is responsible for taking jpeg images from IP camera.
Here is the code for this.
public void paintImage(Image image, int fps) {
try {
int width = this.getWidth();
addToBuffer(image);
currentImage = image;
Graphics graphics = this.getGraphics();
if (isRunning && graphics != null) {
graphics.drawImage(image, 0, 0, getWidth(), getHeight(), this);
if(border ==true){
graphics.setColor(Color.RED);
graphics.drawRect(0,0,getWidth()-1, getHeight()-1);
graphics.setColor(Color.white);
graphics.setFont(new Font("verdana", Font.ITALIC, 12));
graphics.drawString("FPS : " + fps, width-60, 13);
this.fps = fps;
if (isRandomRecord) {
graphics.setColor(new Color(0, 255, 0));
graphics.fillArc((getWidth() - 10), 5, 10, 10, 0, 360);
} catch (Exception e) {
e.printStackTrace();
Can someone please help me to solve this problem so that the CPU usage can be reduced.Can you give me more detail information about how to use
an automated profiling tool You run it and excercise your app. Then it presents stats on number of times each method was called and time spent in each method, plus other stuff. Using those two stats you can zero in on the areas that are most likely to yield resullts. -

Why is the CPU usage different ? I used LOAD_BALANCE option.
I used a oracle 11.2.0.2 in RAC 2 nodes.
And I used LOAD_BALANCE option in the WAS pool configuration
jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.10.118)(PORT=1522))(*LOAD_BALANCE=YES*)(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=NOFFICE)))
But the CPU usage is different between two system. Usually it is 6:4, Sometimes it is 7:3.
Is it normal?
I want to a balance in CPU Usage (5:5).
If it is the better solution about a Load balance. i want to know it.You are partially correct which is another way of saying you are incorrect too.
There are two types of load balancing ... server side and client side. There are also questions with respect to how the client is connecting, we don't know, whether the session load is identical, etc. which the OP has not stated.
The only thing I can absolutely say at this point is that what the OP has seen is normal and I can't see any reason why, unless the skew is very large and very permanent, anyone should care.
To the OP: Let's step back from the "what I want" statement and go to the basis of your inquiry: "Why do you care? Please provide a business reason and cite specific performance metrics, from your system, showing the problem you are trying to address. Then perhaps we can help you. -

Ignacio,
The excessive waits on log file parallel write and the related client wait of log file sync may be due to insufficient CPU availability, and may not point at an actual redo log size problem or a problem with the disk speed where the redo is written to disk, especially if there are 3 Oracle instances on the server with a single CPU.
Paraphrased from "Optimizing Oracle Performance":
The log file sync wait event is one of the first events to show increased latencies due to the time a process spends waiting in a CPU wait queue while processing excessive logical IOs.
Kevin Closson wrote a couple blog entries that examined the potential problems of insufficient CPU capacity and its effects on log file parallel write when writing to solid state disks, and even when writing redo was explicitly disabled:
http://kevinclosson.wordpress.com/2007/07/21/manly-men-only-use-solid-state-disk-for-redo-logging-lgwr-io-is-simple-but-not-lgwr-processing/
"Once LGWR loses his CPU it may be quite some time until he gets it back. For instance, if LGWR is preempted in the middle of trying to perform a redo buffer flush, there may be several time slices of execution for other processes before LGWR gets back on CPU..." Fix the CPU problem, and the other significant waits may decrease.
JesusLuvR,
yingkuan's suggestion to look at the SQL statement that performs the 4,365,564 logical IOs, consumes 186.03 CPU seconds, and has an execution time of 225.06 seconds, is likely a very good starting point. You might also want to check the value of the SESSION_CACHED_CURSORS parameter to see if it needs to be adjusted.

How do you get the CPU Usage in Linux
This is a link of an example in WIN32:
http://www.javaworld.com/javaworld/javaqa/2002-11/01-qa-1108-cpu.html
It notes that UNIX environments should use getrusage(), and that is all it says in regards to UNIX. The code I have attempted to use looks like this:
#include <sys/resource.h>
#include <sys/time.h>
#include "CPU.h"
#include "jawt_md.h"
#include "jawt.h"
struct rusage usage;
int ret;
struct timeval val;
struct timeval val2;
JNIEXPORT jlong JNICALL Java_CPU_getProcessCPUTime (JNIEnv * env, jclass cls)
ret = getrusage(RUSAGE_SELF,&usage);
val = usage.ru_stime;
val2 = usage.ru_utime;
return val2.tv_usec;
}My problm is that I don't think it is right...since the value returned is always the same no matter what the CPU usage is. same for if I used val instead of val2.
Any Ideas?In Linux, you can read /proc/uptime. It does NOT give you the load averages that the command uptime gives. It gives you numerically the amount of time the CPU was idle vs how much time it was spent doing something. You need to read these two floating point numbers one every second, or once every 5 or 10 seconds then do the delta on the change: The maths are as follows:
Read the file in twice in 5 seconds, parse into two floats/doubles:
double[] last; // the first read of the file
double[] rect; // the latest read of the file
double ld = last[1] - last[0];
double rd = rect[1] - rect[0];
double cpu = (1.0d-(rd/ld)) * 100.0d;This should print the CPU percentage in Linux for that given time frame (5 second updates). -
Can anybody help me to understand the CPU usage logs
Hello community,
I try to find the faulty machine in our network, but I don`t understand the logfiles. We have many servers which normally work very fast and reliable.
But sometimes we have such a huge cpu usage drain on our server. Nobody knows where it comes from, so I looked in the vsphere web client and looked in the cpu usage logs.
Following you can see two pictures. One is from the main host. It shows only a cpu usage of a maximum of 45 %.
When I look on the vmware machines I can see a cpu usage of more than 150%.
This is something I completely not understand. How is it possible that the main host machine has only a 45% cpu usage and the clients are exploding?
I don`t have set a cpu usage limit in our resource pool.
The next thing is. When I look on the vmmachines, I can not identify the faulty machine. Because when one machine increases the cpu usage many others increase too. Whatever why.
Can somebody explain me the pictures below please:
Thank you for your time
PaulYou don't have any need to understand this code. The complication is due to the registry needing a fixed objectID.
You just need to know the methods of java.rmi.registry.LocateRegistry class. This allows you to start an RMI Registry inside your JVM and give it any TCP port number you like. -

The CPU usage is 99% everytime I start firefox. When I open help tabs in the browser to troubleshoot the problem the cpu goes down to normal.How am I supposed to troubleshoot the issue if the last resort is as simple as uninstalling firefox?
Running: Firefox 5.0
OS. H.P. Windows XP/ sp3 , mem. 1536 MB , Pent.4.Hi musicfan,<br />Sorry you are having problems with Firefox. Maybe you should have asked earlier and we could have fixed it.
Reading your comments I do not see that rolling back to an insecure Firefox 22 will actually help you much. You are probably best using IE, unless you have also damaged that.
*[[Export bookmarks to Internet Explorer]]
You should not use old versions they are insecure. Security fixes are publicised and exploitable.
* [[Install an older version of Firefox]]
* https://www.mozilla.org/security/known-vulnerabilities/firefox.html
Most others will not be having such problems. We are now able to say that with confidence because after developers missed a regression in Firefox 4 telemetry was introduced so that data was obtained. It may be an idea to turn on your telemetry, if you have not already done so, and decide to stick with Firefox.

Trying safe mode takes seconds. Unfortunatly if you are not willing to do even rudimentary troubleshooting there is not anything we can do to help you.

Stripchart control, strange high CPU usage
Hi all...
I have tracked a strange problem with stripchart control.
I noticed in the past that "sometime" different programs I wrote had an abnormal CPU usage, not justified by any activity they were actually performing.
Finally I had the time to track down the problem and to build a minimal sample code.
The presented program has a panel with a stripchart control and two command buttons.
The buttons simply clear the stripchart and add a single point to the empty stripchart.
int CVICALLBACK ControlCB (int panel, int control, int event,void *callbackData, int eventData1, int eventData2)
switch (event) {
case EVENT_COMMIT:
switch(control) {
case PANEL_BUG:
ClearStripChart(panel,PANEL_GRAPH);
PlotStripChartPoint (panel, PANEL_GRAPH, MAGIC_VALUE);
break;
case PANEL_NOBUG:
ClearStripChart(panel,PANEL_GRAPH);
PlotStripChartPoint (panel, PANEL_GRAPH, NOT_SO_MAGIC_VALUE);
break;
break;
return 0;
I found that adding "special" values to the stripchart starts a background activity that consumes a significant amount of CPU time.
In this screenshot you can see what happens on my PC when I click the "Bug" command button.
The special value is here 42.22 but I bet there are other thousands with similar behaviour.
Being a single point, the stripchart does not show nothing but the change of the Y axis scale.
Clicking the "No Bug" command button inserts the value 100.0 and no bad behaviour occurs.
Just to shuffle ideas, if you push "No Bug" and then "Bug", the bad behavior does not occurs, too.
It's surely an interaction between the Y axis autoscale, the initial values and may be the "scale name". I haven't the time to explore all the combinations and may be a minimal workaround.
In my applications I ended in doing the autoscaling "by hand".
I have tested the program on five different PCs, Core 2 Duo CPUs running XP, Vista and 7 (italian), compiled with CVI 2010 SP1
Attached there is the full project.
The distribution kit for the project (no sources) can be downloaded here: http://dl.dropbox.com/u/23913808/CPUeater.zip

StripChartCPUeater.zip 5 KBThere was a bug in the graph/strip chart code which could cause endless cycling when attempting to resize a graph axis which had an axis label visible. It has been fixed for the next version of CVI so unfortunately you're going to have to wait a little bit.
There are two possible workarounds:
1) disable the axis label. If it isn't displayed, this looping can never occur.
2) Enable Fixed plot area and play around with the left and width of the plot area to move the whole thing over to the right a bit more. The problem was introduced when the graph/chart thinks the label is getting too close to the edge of the graph and attempts to reposition the label. Unfortunately the code was a little buggy and the label was getting positioned in the exact same spot, but we weren't checking to see if we'd already tried to reposition the label, and so it endlessly cycled.
Sorry about the inconvenience.

How to lower the CPU usage level?
My CPU usage level has always been over 90% even after i restart my mac book pro, what should i do?
u09mi7
You can launch activity monitor to see what processes are using what amount of CPU. Also there is an application called AppTamer it is a sharware program and has gotten good reviews. It helps to reduce CPU usage on programs that are kind of in the background, one's you're not using at the moment. I would also recommend iStats Menu which monitors are the vital systems, memory, cpu, temps, disk activity etc...if you don't want to pay for the license the dashboard widget iStats Pro is free of charge and does the same thing. Do you have a lot of apps starting as login items? Hope this helps. Follow up and let us know how things are working.
