Data log format like JDK logging

Hello:
I'm working with SUNONE AS
Source classes belong my application use Java logging ( JDK 1.4.2 ) , but logs ( in instance's server.log ) don't be written in Java logging format, i.e, class name & method name where log method ( by example, info() ) call is invokated
How can I do for logging calls into my code to write in Java logging format ? How I can to configure my SUNONE AS ? Must I change logging properties file in jre/lib ?
Thanks in advance
Best regards

Hi,
I think you change the format as you using TraceFormatter class.
According to the pattern you give in the constructor your format will change.
It is that pattern that determines.

Help please: DAQWare or data logging software (multichannel data capture) questions

I am writing regarding DAQWare, data logging software, and the PC-LPM-16
board, which a group of us a trying to come to grips with. This is rather
lengthy, I'm afraid...
We are a group of college students in a computer programmer/analyst
program. We have a course that involves doing a project to go through the
software development lifecycle (or as much of it as can be done in a term).
For our project we teamed up with a group in the industrial hygiene
program; they have a computer (standalone) with a PC-LPM-16 (PnP) DAQ board
and the NI-DAQ software (all of this has been around for a few years, but
has not been used much), and our goal was to capture the data they are
measuring (atmospheric pollutants) to an Microsoft Access database.
We are not familiar with DAQ systems, but were shown the software they had
installed. This included DAQWare (appears to be version 2.0). We thought
we could use DAQWare to log data to a text file, which we then would import
into the Access database. We came up with VBA code to parse the ASCII text
file created, but have run into one problem: DAQWare does not timestamp
each sample, but only puts a single timestamp in the header information.
Now we could extrapolate the time for each line based on the sample rate,
except that sometimes it seems to put in 8 values per sample, sometimes 12
values. For instance, in the sample of a text file below, the capture was
run for 1 minute at a sample rate of 60, and there were 480 measurements in
the file, or 8 lines of measurements per sample. (At a sample rate of 100,
we got 800 measurements in the file etc.) This was two weeks ago. Today,
we returned to capture more data, and DAQWare was logging 12 measurements
per sample (so at a sample rate of 100, we ended up with 1200 lines of
measurements). We do not know where this factor of 8 or 12 is coming from
or how it got changed in the two weeks between captures. We would like to
be able to have them just run DAQWare, for days on end if they wanted,
capture the data to file, then use our code to parse the text file into the
database, but if we cannot put timestamps on the readings, there seems no
point.

Regarding this attempt to use DAQWare:
1. Can you tell us where this factor (8 or 12 or however many more readings
than we would expect) means, where it is read from or set?
2. Is there an updated version of DAQWare that we should download that
would be better?
3. Is there some other existing software that we can download to use to
perform basic logging of multichannel analog input to a text file (with
timestamp)?
I realise that the software comes with tools (DLL functions) that one can
use to create custom software to interface with the DAQ board, but in the
limited amount of time we have we are not sure we can learn enough about
these functions to write our own datalogging software.
However, to see if I could grasp the basics, I have looked through the
examples for Visual Basic and think that a program would run something like
this:
1. at the beginning, use LPM16_Calibrate to reset the board
2. configure acquisition with DAQ_Config
3. start acquisition with Lab_ISCAN_Start
4. loop to check is acquisition done with Lab_ISCAN_Check
5. once sampling done, write data out to file
6. loop back up to 3 to get next lot of samples
Unfortunately, a sample app using Access and VBA I created came back with
an error telling me it could not find nidaq.dll (even though this is in the
Windows system directory); probably it is not a good idea to try to do this
in Access in the first place. I am going to have a go using Delphi, which
I know a bit better.
One thing I am unsure of is what the numbers will be coming out of
Lab_ISCAN; the reference file seems to indicate they will be binary
readings, not voltages, and I wonder how to correlate these with instrument
measurements (the instrumentation people we going to set it up so that
1mV=1ppm).
Any help you can give to point us in the right direction would be
appreciated.

Hey,
You can build your own runtime menu (Edit>runtime menu) and then e.g. only display the application items you want to.

How can I perform data logging for a specific time??

hello everyone,
I am quite new in labview and I have a basic question regarding data logging. Currently I am using a cRIO9074 and doing some data logging for my test. The data logging it self works ok so far.
But my problem is I would like to write my datas in a text file either for a specific time interval (ex)10 seconds) or for a specific amounts of data (ex)500 Samples). Can anyone give me some help regarding my problem?? Attached you can find my RT.vi
I would appreciate for anyhelp!

Run your loggging program for that time. When your program terminates then it will write all the logged data so far in text file.
Kudos are always welcome if you got solution to some extent.

How do I control a data log session with period and sample time?

I need a data logging system where the operator can select 2 logging parameters: Log Period and Sample Time. I also need a START and STOP button to control the logging session. For example, set the log period for 1 hour and the sampling time for 1 second. (I may be using the wrong jargon here.) In this case when the START button is clicked, the system starts logging for 1 second. An hour later, it logs data for another second, and so on until the operator clicks the STOP button. (I will also include a time limit so the logging session will automatically stop after a certain amount of time has elapsed.)
It’s important that when the STOP button is clicked, that the system promptly stops logging. I cannot have the operator wait for up to an hour.
Note that a logging session could last for several days. The application here involves a ship towing a barge at sea where they want to monitor and data log tow line tension. While the system is logging, I need the graph X-axis (autoscaled) to show the date and time. (I’m having trouble getting the graph to show the correct date and time.) For this application, I also need the system to promptly start data logging at a continuous high rate during alarm conditions.
Of course I need to archive the data and retrieve it later for analysis. I think this part I can handle.
Please make a recommendation for program control and provide sample code if you can. It’s the program control concepts that I think I mostly need help here. I also wish to use the Strip Chart Update Mode so the operator can easily view the entire logging session.
DAQ Hardware: Not Selected Yet
LabVIEW Version: 6.1 (Feel free to recommend a v7 solution because I need to soon get it anyway.)
Operating System: Win 2000
In summary:
How do I control a graphing (data log) session for both period and sample time?
How do I stop the session without having to wait for the period to end?
How do I automatically interrupt and control a session during alarm conditions?
Does it make a difference if there is more than one graph (or chart) involved where there are variable sample rates?
Thanks,
Dave

Hello Dave,
Sounds like you have quite the system to set up here. It doesn�t look like you are doing anything terribly complicated. You should be able to modify different examples for the different parts of your application. Examples are always the best place to start.
For analog input, the �Cont Acq&Chart (buffered).vi� example is a great place to start. You can set the scan rate (scans/second) and how many different input channels you want to acquire. This example has its own stop button; it should be a simple matter to add a manual start button. To manually set how long the application runs, you could add a 100 ms delay to each iteration of the while loop (recommended anyway to allow processor to multi-task) and add a control that sets the number
of iterations of the while loop.
For logging data, a great example is the �Cont Acq to File (binary).vi� example.
For different sample rate for different input lines, you could use two parallel loops both running the first example mentioned above. The data would not be able to be displayed on the same graph, however.
If you have more specific questions about any of the different parts of your application, let me know and I�ll b happy to look further into it.
Have a nice day!

Which is the best structure for start/stop data logging?

Hi everybody,
hope I can explain my problem good enough that anyone can help me:
I have a VI which continuely shows on a graph the voltage of a Analog Input of a DAQ device. Now I want to allow the user to start/stop with a click on a button data logging. Means that a second loop writes to a selected path every ms the data to a spreadsheet file.
At the moment my VI works like this:
You run the VI and Labview asks you one time for the file path, then you can start and stop the data logging. But you can do it only one time. If you want to log a certain time later another file, you have to close and open the whole VI again which is not very professional...
My target is:
It is onlyl necessary to start the VI one time. Then you can select a new file path, log data, select another file path, logging data again....and so on...
Which programm structure is necessary, can anyone help me as a labview beginner with that issue? I attached the VI if someone just wants to edit that...
Thank you for your help!! Markus

@NaruF1 and GerdW
you are right, there is a mistake, both loop rates should be the same (10 ms) :-)
@NaruF1
yes you understood correctly that the file dialog should appear every time the user wants to start writing a new log-file. The voltage we measure is a analog signal, so there will be several interesting periods we want to save for a later analysis in Excel.
To your 2nd point: if it works with a array it will be fine. But it must be possible to log data for lets say 5 minutes, so the array won´t be too large? (5 min @ 10 ms loop rate will be 30000 rows..
attached is the VI, saved as LV2009..
Thanx a lot!
@GerdW
..you ask why I didn´t create a structure like you recommended with notifiers or queues? The simple answer would be that I am not familiar with all this.. just began to write my first Labview programm. I will have al look to the LV help with all that stuff... Thank you a lot

Data logging optimization function in LabVIEW and SignalExpress

Hello, everyone! I and a colleague have assembled the attached VI,
which is used to control a plant growth chamber, and I could use some advice.
I would like to add data logging capabilities, ideally to note (1)
environmental conditions, such as temp and CO2 level and (2) when certain
situations occur, such as high CO2 or low pressure (which results in a change
to the “Case Structure for CO2 and Pressure”).
The chamber runs for weeks at a time, though, so I have a constraint.
Instead of continuously logging all the environmental data (which would yield
giant file sizes), I want to be able to take “snapshots”, say every 5 minutes,
so I can examine the chamber’s condition over a long period of time.
I attempted to use the Time Delay function to control the Write Measurements
function (as in LabVIEW’s Cycle Analysis example, which I’ve also attached),
but Time Delay halted my entire program.
I also tried the Wait (ms) function, but had no success.
I recently discovered the powerful data review and reporting tools that
SignalExpress has to offer. Ideally, I
would like to use a SignalExpress express VI to record the measurements instead of the more primative Write Measurements, but, I’m not sure how to implement this in my VI. For example, would I make a data acquisition VI in SignalExpress for all my sensors, export to LabVIEW, and use that to replace the current DAQ structure in my VI? (Because the chamber VI is interactive, I'm pretty sure that porting the LabVIEW VI to SignalExpress wouldn't work out well.) And I’m
still not sure how to control how often it records measurements.
Any advice would be much appreciated!

Hi, Sarah. Yes I definitely plan to use LabVIEW for the majority of my data acquisition and logging. I apologize, I think I probably should have broken my post into two separate posts for clarity, as my major concern is being able to set how often LabVIEW logs the environmental data (viewing the logged data in SignalExpress would be nice, but not a requirement).
As I explained before, I'd really like to be able to set up a system that records the environmental condtions at regular time intervals, say every 30 minutes, or if my "Case Structure for CO2 and Pressure" status changes (such as from "Normal Conditions" to "High CO2".
As an example, attached is a boolean structure (TimedWritedMeasurements.vi) that I came up with to record a simulated signal every 5 seconds (5000 ms). Once I can get it to work, I would connect the boolean to my environmental sensor outputs and CO2 and Pressure case structure in my Chamber VI.vi that I attached in my first post.
My problem is I can't seem to get the Trigger and Gate function to work the way I'd like. I'd like the Wait (ms) function to trigger the Trigger and Gate function every 5 seconds to change the case structure in the TimedWriteMeasurements.vi to "True", thereby causing the Write Measurement function to record the environmental conditions. Then I'd like the case structure reset to false, until it's triggered to true in another five seconds. Can anyone point me in the right direction?

Good morning,
Without the instrument it might be hard for others to help
troubleshoot the problem. Was there a
specific LabVIEW programming question you had, are you having problems with the
instrument communication, are there errors?
I’d like to help, but could you provide some more specific information
on what problems you are encountering, and maybe accompany that with a simple
example which demonstrates the behavior?
In general we don’t we will be unable to open specific code and debug,
but I’d be happy to help with specific questions.
I did notice, though, that in your logging VI you have at
least one section of code which appears to not do anything. It could be that a small section of code, or
a wire was removed and the data is not being updated correctly (see pic below). Is your file being opened properly? Is the data being passed to the file
properly? What are some of the things
you have examined so far?
Sorry I could not provide the ‘fix’, but I’m confident that
we can help. Thanks for posting, and
have a great day-

I have an optical sensor and two hall effect how can I data log?

I have built a test rig which consists of a gyroscope. The gyro is spun up by and electric motor.
I need to measure the speed of rotation. I’m using an optical sensor and two Hall
Effect sensors. I would like to record the
output of these and I would like to build in some redundancy because there will
be another bigger rig that will require more measurement. E.g. vibration.
I’m new to data logging so I’m not sure which hardware I
should be getting.
Thanks

analog inputs are the most universal. with software such as the functions included in the Sound and Vibration Measurement Suite, you can analyze the analog input channel which is connected to your hall effect and optical sensors for frequency and speed. Vibration specific input cards will power accelerometers. with the speed and angular position sensors (hall effect and optical) you can combine this information with your vibration sensors to determine the movement of the device with respect to position and speed. These order analysis functions are part of the Sound and Vibration Measurement Suite.
What is more is that the Suite includes an assistant. The assistant allows for the capture and datalogging of all analog and digital inputs as well as frequency and vibration analysis. This is all configurable and does not require any LabVIEW programming. If you decide you want LabVIEW programming, all the functions are there to support LabVIEW as well.

Smart camera / vision builder data logging

Hi
I have Vision Builder 3.5 with a NI-1722 Smart Camera. I have the inspection working as I need it to but I need to log the failed data. I just can not seem to get this to work. I have attached a couple of photos of the program and hope I can get some suggestion on what I need to do. What I am trying to do is inspect if the light is on and if one of the light do not come on. The data I need is which light did not come on and at what time this occurred. When setting up the data logging Icon I direct it to the folder I want and give it a name but nothing is ever logged. I have been trying to figure this out for about 12 hours now I need some help please.

N95 Packet Data log duration won't clear

I would like to know if anyone else has experienced a fault that I have with my N95 8G running the latest version of software.
The fault is around the Packet Data log.
I want to be able to keep tabs on my daily data usage, so have set the log duration to 1 day. When I check the packet data counters the following day, they have not reset. I have left the counter running for 7 days now and they still haven't reset.
Maybe I don't understand this feature, but I was expecting the counters to reset after 1 day.
Nokia support have sent out their standard 'we have no idea wants wrong' email requesting me to return the phone back to factory setting and loose all my data, which I'm reluctant to do.
Cheers,
Paul

The "keep logs for" feature does not affect the counters.
All it does is keep individual events for the specified duration.
Enter the "logs" application and then scroll right. You'll see a list of logged events (calls, messages in/out, packet data usage etc). THESE are the entries kept for one day with your settings.
Was this post helpful? If so, please click on the white "Kudos!" star below. Thank you!

Has someone installed some kind of data logging *SPYWARE* on my iMac?

I found a file I don't recognize sitting in my ~/Library/Preferences folder called "HOME Preferences".
This 4K file contains this:
UserLocale=en_US
LastUsedDeviceTypeName=go720
UserPatchFeedback=0
UserPatchFeedbackAddress=
ConfirmedAnonymousDataLogging=1
HaveSendAnonymousDataloggingReply=1
BackupPromptDevices=M64048D01413
StartUpWindowBounds=-7,22,1816,999
.. and that's all. IS this a symptom of some kind of spyware installed or attempted to be installed without my knowledge by someone else who had access to my machine? The datalogging settings bother me as does a setting for user feedback of 0 which sounds like a setting to keep the presence of a datalogger quiet from popping up or showing. How can I figure out using unix commands in the terminal or something more convenient what application this preference file belongs to? This file has an install date of late 2008, so if someone is spying on me, they've been doing it over a year without my knowledge--that disturbs me a bit. I was nosing around trying to figure out why this G4 macMini which is supposed to be recording my two household security cameras has been running so poorly. I have no idea what this file installed on it is all about. I don't believe it to be related at all to the Security Spy software I use for recording the cameras feeds to hard disk.

First off, don't panic.
'Data logging' can mean many things, and take many forms - not all of which are nefarious.
If you think about it, it would to be a pretty dumb hacker who infiltrates your machine to install a logger and leaves such a big, bold footprint behind.
That said, I don't know what this relates to, specifically, but a quick google on some of those keywords (especially the LastUsedDeviceTypeName) hints at something to do with a TomTom GPS unit. Did you install/attach a TomTom GPS back in 2008 when this preference file was attached?
Data logging is often used in GPS terms to track paths/routes, so it would seem to make sense.

CRio data logging too slow

Hi,
I am using a cRio 9074 in scan mode and I have a fairly simple timed loop that should run at 5-10mSec periods to operate a pwm control. I also need to do some data logging and save two input signals (at approx. 1kS/sec). However, when I use write to spreadsheet, the loop speed drops and my timed loop period goes up to 50mSec. How can I speed this up, and what is the efficient way to save data in scan mode.
Thanks.
Solved!
Go to Solution.

The single best way to improve determinism is to divide your acquisition/logging into two distinct producer/consumer loops as VTHokie says. Next best improvement would probably be using a binary format file structure rather than Write to Spreadsheet, which converts all data to ASCII representation prior to writing to file. Writing to ASCII files rather than binary files degrades performance in four ways:
CPU must be used to do the number to text conversion
ASCII represented numbers lose precision and don't exactly convert back to original data
The filesize is larger
When you go to read the file, it's slower for the above three reasons
On the other hand, an ASCII file is more portable - e.g., you can easily import into a third-party spreadsheet analysis program. But who in their right mind would export data OUTSIDE of LabVIEW when it offers best-in-industry analysis tools?
a.lia-user-name-link[href="/t5/user/viewprofilepage/user-id/88938"] {color: black;} a.lia-user-name-link[href="/t5/user/viewprofilepage/user-id/88938"]:after {content: '';} .jrd-sig {height: 80px; overflow: visible;} .jrd-sig-deploy {float:left; opacity:0.2;} .jrd-sig-img {float:right; opacity:0.2;} .jrd-sig-img:hover {opacity:0.8;} .jrd-sig-deploy:hover {opacity:0.8;}

Data Logging SCC-68

How fast can I sample the DAQ. I'm taking 4 analog inputs and writing them to an ASCII via LabView SignalExpress.
I keep getting buffer overflow errors saying that the sample period is too short. I'm currently at 20ms.
How short can I make it? It seems a bit ridiculous that this thing can't sample at <50Hz.

Ok, I'm actually in LabVIEW now. I have a DAQ Assistant outputting 4 analog signals to a Write to Measurement File which is creating a .lvm
It actually seems to be working now thanks to you. I thought the Continuous Sample option did something else, but it is working fine now, thanks.
One last thing, is there a way to get the time stamp to be in regular format? I'm planning on comparing the data from this to another data log to look for a certain phenomenon going on. Right now I'm just pressing go when the second hand on the computer gets to :00.
Thanks again for the help,
Colin

Data log format like JDK logging
