Help needed in getting real time system performance monitor

Hi,
I need a real time system performance monitor for my solaris.
i am able to graph system usage graph on a daily/weely basis using the ksar grapher.
In the same way i need to capture the system utilisation real time to be viewed on a webpage. Please let me know if there are any free tool/scripts capable of doing it.

Help needed with CVI real time

Hi,
I am new to CVI real time and need help related to this. I will explain my scenario:
1. I have few configuration files (INI). Need to validate the files (range checking..etc) during start of the application.
2. When user clicks "START" in the user interface on the host machine, I need to generate outputs (analogs/discretes...) based on the settings in the config file and read some inputs from other instruments. ( I/O tasks like generating outputs/reading inputs i am planning to perform in RT side)
3. From the user interface, user can also change the config files. if user changes the files, again file validation needs to be performed. After changing the files, if user clicks START, need to take the newly enetered config files to perfom I/O tasks.
4. I am NOT using reflective memory for my application.
I am confused in the following area:
1. File validation during startup , do i have to perform on both host and RT side?????
2. if configuration files are changed in the host side by the user, how i have to send this latest file names to RT??? I think i should not send file names, i need to read from the file and its contents i need to pass to RT....Pls correct me , I am not sure about this....
3. If I have to send file contents to the RT, how I have to do that....means i have to use structures,..???
Please guide me. Any help would be highly appreciated.

Hey haari,
1. File validation during startup , do I have to perform on both host and RT side?????
This depends on the full range of responsibility for the INI files. If they are all needed simply to change what the I/O tasks are for, then you would technically only need to validate the INI file contents on the RT side. You could, however, validate on both sides if you wanted to. However, I would probably set it up such that I send a validation command to the target, have the target run a component of the code that validates the INI contents based on how I instructed it, and then return a message that says whether or not it met the requirements I specified. However, if you are concerned with offloading that process to the user desktop (instead weighing down the RT controller performance), you could FTP the file off of the controller and perform the validation process on the host side.
2. if configuration files are changed in the host side by the user, how i have to send this latest file names to RT??? I think i should not send file names, i need to read from the file and its contents i need to pass to RT....Pls correct me , I am not sure about this....
You can send them to the target over FTP. This can be done programmatically, through MAX, command window, or a Web browser.
3. If I have to send file contents to the RT, how I have to do that....means i have to use structures,..???
This is basically addressed in answer to question two. You would not need another structure in your RT code to handle the FTP receive component as this is handled by the FTP Client/Server communication. However, in the event that you successfully FTP a file to the target, you should likely send a message from the host to the target so that the target can respond accordingly and reload the file, reestablish the I/O values, run an idle procedure, or do whatever you like.
Hope this helps. Have a great day!

I need to get the Current System Date and time in the format

I need to get the Current System Date and time in the format
*6/24/2009 11:30:29 AM*
How do i do it ?

I seem to be saying this a lot lately.
Google is your friend.
I googled "java current date format" and SimpleDateFormat featured prominently in the results.

Java Real-Time System HotSpot(TM) Client VM warning: unable to lock pages i

Error:
Java Real-Time System HotSpot(TM) Client VM warning: unable to lock pages into memory
I'm getting this error, although I have assigned all the needed privilegs to root and I am logged in as root. I have done everything described in the guidelines to get the privilegs, but still this warning occurs.
But my application still works completely with no appreciable differences.
So my question is: Does this warning affect the performance of my application?? Or can I live with this warning?
Gordon

Determinism is an important issue in my application. That's why page locking should be active in my application. When I'm determining the ScopedMemory size via VM like:
... -XX:ScopedSize=500000000 ...Then page locking works with a size of 500 mb very well. But when I try to set the ScopedSize value to 1 gb, then the exception (unable to lock page...) is thrown. So it seems as if I had all the required rights, but the huge size is not supported.
The System has about 6 gb of DDR2Ram and minimum 5 gb are free during starting the VM. So are there any other parameters except ScopedSize that I can change, to allow the VM to lock memory with a size of about 1 gb? Or where is the problem with locking such big sizes?
Thanks,
Gordon

Hello
I have a VeriStand-Project (VSP) created with my Laptop-Host (LTH) which works with my PXI, while
deploying it from my LTH. Then I have installed the whole NI enviroment for PXI and VeriStand use on a
industrial PC (iPC). I have tried to deploy my VSP from the iPC to the PXI but the following error
message arose on my iPC:
The VeriStand Gateway encountered an error while deploying the System Definition file.

The software versions of the NI products (MAX/My System/Software) between my LTH and the iPC are
almost the same. The only differences are:
1. LabView Run-Time 2009 SP1 (64-bit); is installed on LTH but missing on iPC. The iPC has a 32-bit system.
2. LabView Run-Time 2012 f3; is installed on LTH but missing on iPC.
3. NI-DAQmx ADE Support 9.3.5; something strage on the LTH, because normally I am using NI-DAQmx 9.5.5 and all other DAQmx products on my LTH are 9.5.5. That means NI-DAQmx Device Driver 9.5.5 and NI-DAQmx Configuration 9.5.5.. On the iPC side all three products are 9.5.5.. That means NI-DAQmx ADE Support 9.5.5, NI-DAQmx Device Driver 9.5.5 and NI-DAQmx Configuration 9.5.5..
4. Traditional NI-DAQ 7.4.4; The iPC has this SW installed. On the LTH this SW is missing.
In order to fix this problem I have formatted my PXI and I have installed the following SW from the iPC:
1. LabVIEW Real-Time 11.0.1
2. NI-488.2 RT 3.0.0
3. NI_CAN 2.7.3
Unfortunately the above stated problem still arose.
What can I do to fix this problem?
I found a hint on http://www.labviewforum.de/Thread-XNET-CAN-die-ersten-Gehversuche.
There it is written to deploy the dbc file againt.
If this is a good hint, so how do I deploy a dbc file?
I would feel very pleased if somebody could help me! :-)
Best regards
Lukas Nowak

Hi Lukas,
I think the problem is caused by differenet drivers for the CAN communication.
NI provides two driver for CAN: NI-CAN and NI-XNET.
NI-CAN is the outdated driver which is not longer used by new hardware. NI replaced the NI-CAN driver with NI-XNET some years ago, which supports CAN, LIN and the FLEXRAY communication protocol.
You wrote:

3. NI_CAN 2.7.3
NI CAN is the outdated driver. I think that you should try to install NI-XNET instead of NI-CAN on your PXI-System, to get rid of the error message.

SetAsyncTimerAttribute ASYNC_ATTR_INTERVAL fails to reset timer on Real-time system

The interval timer does not get reset when using a timer created in a real-time program (PXI chassis using NewAsyncTimerWithPriority). It works correctly on a non real-time system (Windows 7 Laptop using NewAsyncTimer).
Example of problem:
timer is set to 20 seconds (NewAsyncTimerWithPriority)
wait 15 seconds
timer interval is set to 30 seconds (SetAsyncTimerAttribute ASYNC_ATTR_INTERVAL)
timer fires 5 seconds later instead of 30 seconds
GetAsyncTimerAttribute returns the correct value as if it worked properly. Note that the timer fires every 30 seconds after the early firing in step 4. It appears that changing the interval on a real-time system does not reset the timer as stated in the help file "If the timer has already started, setting ASYNC_ATTR_INTERVAL resets the timer."
Am I doing something wrong? Has anyone seen this problem?
Using: LabWindows/CVI 2012, Real-time module 2012.
Also installed: LabView 2012, Real-time module 2012, FPGA module 2012.
Thanks.

Hi Moxcoak,
You are right this is a known issue, the async timer does not reset properly in a RT system from CVI. We have already filed a bug report on it (#387902) and I will add your service request to that corrective action report to hopefully push it to be resolved faster. Meanwhile, I will try to find the best workaround for you. One option is to set a flag with the communication thread and check it with another asynchronous thread. I will get back to you with the details on how to implement that, but it would depend on your setup.

How to get real time information about how many user are logged in and thei

I use tomcat as my server platform in Ubuntu for a war file.
I know in order to get real time information about how many user are logged in, we can count how many active sessions exist by a SessionCounter code. However, I have to permit HttpSessionListener in web.xml of tomcat. From other users' experiences, the configuration is complexed and has some errors.
Here's the link:http://www.stardeveloper.com/article...1112001&page=1
In order to get users' ip, in jsp, use request.getremotehost() or
request.getremoteaddress() by editing the jsp file.
I wonder if there's some open source software to use for these two purposes.
Thank you!

That url is missing a few bits. The ... in the middle doesn't help.
we can count how many active sessions exist by a SessionCounter code.
However, I have to permit HttpSessionListener in web.xml of tomcat.
From other users' experiences, the configuration is complexed and has some errors.And have you tried it? The configuration isn't that complex.
What errors do you mean? Errors in tracking people, variance in the count? Probably related to internet issues and nothing you can do will alleviate them.

Need SD,MM real time scenarios

hi everyone, Plz help me with SD real time scenarios with examples..
regards,
prashanth

Business scenario that has to be mapped by you (SD consultant) -
Company / client is a TV manufacturing company which sells TVs and provides TV repair sevices.
1. Sales orders for both (TV selling & services) must be done in one sales document type
2. Delivery type must be set up ONLY for TV selling (as services do not need any delivery of goods!)
3. For easy identification - bills should have different number ranges. For selling TV bill # must range from 1 to 1000, and for TV services from 90001 to 90099
4. TV selling must be delivery related bill, TV service must be order related bill
How shall you configure this in SAP SD? What are the important questions you will ask the client, for more information?
Once you have attempted this we can go a step further (in to more functionalities)

Works the same exact way on my system. How Redo Data is applied is set when the database is MOUNTED.

Where to find Java Real-Time System Evaluation

Hello,
I tried to download an evaluation version of the Java Real-Time System from this page: http://www.oracle.com/technetwork/java/javase/tech/rts-142899.html
But, when i try to download the "Java RTS 2.2 - Academic Developer Use" for Linux x86 32bit, i get the following message: "The Java Real-Time System evaluation program is closed at this time."
Is the evaluation program expired? Where could i find an evaluation version of JRTS?
Thank you all for your attention,
Greetings.

Is there support for the AC-1000 target real-time system?

Hi,
Is NI supporting the AC-1000 target real-time system? We've used MatrixX, SysBld, Autocode, and Realsim to compile, link, download, and run various control models on the target real-time system for interfacing with hardware. The AC-1000 has 2-3 processors running a pSOS Operating System, multiple I/O boards, and a MIL-STD-1553 bus. It's connected to an NT workstation via a LAN and a serial cable.
So, any information regarding support and maintenance would be very helpful. Thank you for your time!
Take care,
Chris Holmes
Senior Modelling and Simulation Engineer
United Defense, L.P.

Although NI acquired MATRIXx, we did not acquire the RealSim hardware (AC-1000, AC-104, and PCI-Pro). Wind River retains the ownership of the hardware but is not supporting the product line. Wind River has made available the attached parts list for the RealSim hardware so that customers can self-service existing systems.
NI doesn't plan to develop or support RealSim - and is directing customers who wish to continue to use this software/hardware to 3rd parties. The following NI Alliance members can provide RealSim support.
iControl: www.icontrol-inc.com
ADI: www.adi.com
OPAL-RT: www.opal-rt.com
NI plans to make it easy for customers to target NI hardware, including real-time PXI, with MATRIXx in the future. For information on P
XI, please refer to the PXI section of the ni.com site at ni.com/pxi.

Using wireless network with Real-Time system

Hi,
Has anyone tried to run a LabVIEW real time system communicating over a wireless network instead of wired Ethernet? Thanks.

I would think that all you need to do is hook it up to a wireless access point and the system - whatever it is - wouldn't even know it was hooked up wirelessly...

How can I save/write data on the hard disc of the Real-Time System?

I would like to acquire huge size of data via LabView Real-Time System.
Since data is so huge, I am now thinking that it might be good idea to
write/save data on the hard disc of the Real-Time System first and then
transfer the data file to a data processing PC using FTP etc.
If you know how to save/write data on the hard disc of the Real-Time System
(Ver. 7.1), please let me know.
Thanks,

Just to add to Aitortxo's good answer,
Since you have only one Drive ( C:\) on your RT, just keep monitering the availible disc space.
After every few set of file writes keep transferring Backups delete these files, so that you keep C:\ drive space for running your applications.
