Logging WLDF

Hi all,
This had probably been answered so apologies. Can't seem to find out
how I can grab a simple log of JDBC Connection Pool info, Session info,
and THread Usage while we are stressing our system our system, without having
to look at the admin console.
I know I can appopint Diagnostic Modules and collect Metric Info through the different MBeans,
but I can only seem to view them through the console and this makes it very difficult to make
a document later of the metrics gathered. I'm surprised I can't get a clean log of the specific different
metrics I'm collecting in this advanced stage of the product. Unless I'm missing something, which is probably the
case.
I'd appeciate any information or clues..
Thanks
Vishal

Hi Vishal,
Have you tried taking a WLDF image at the time when you want the information and then open them using WLDFBrowser?. It has to give you the required information.
If you require WLDF Browser, please follow the below link.

WLDF logs for a weblogic cluster

I have a requirement wherein I need to extract useful data from the wldf logs(e.g EventDataArchive).
This has been successful when I have a single wl server running, using jmx call. But when it is a clustered wl environment, I am not getting a single point from where I can get wldf data . In other words , is there a single place in a clustered wl environment which archives data together for each of the managed servers, so that I can fetch the required data from it irrespective of from which managed server it came from .
Thanks,
Naba

A solution to this could be to use JDBC Datastore for all the servers in the clusters; which becomes a single point of storage for all requests irrespective of the server used.

Is it possible to monitor server standard out logs with WLDF

Does anyone know if there is a way to configuring a monitor to watch a managed server standard out log instead of the managed server's server log? I know you can redirect the standard out log to the server log, but it looks like you can't redirect debug or info level messages. Every once in a while the JVM crashes because of an app deployed to one of my servers. I want to alert someone to check on the server to see if its restarted by nodemanager, but the message appears as a [DEBUG] message in my standard out log which it doesn't look like can be redirected to the server log.

Hi
Yes, you can generate list of server with registry key.you need to create a custom class bases of local application and create a registry filtered discovery to check reg key is present.

Note : scom is monitoring tool but not an assert inventory tool, i do not recommend any mp configurations for reporting.

Configuration of logging severity

Hello everyone,
I am trying to use the weblogic Admin console to modify the logging severity at runtime. I have an application deployed on the AdminServer.
In the web console, I go to the AdminServer Settings page and navigate to the Logging tab. I click the "Advanced" link to show the "Logger severity properties". In this box I have tried entering many different values. I save. There is no change to the logs. I restart the server, there is still no change to the logs.
Some values I've attempted to use:
com.mycompany.level=Trace
com.mycompany.level=Debug
com.mycompany=Trace
com.mycompany=Debug
.level=Trace
.level=Debug
I am using weblogic 10.3.2.0 with jdk logging.
Does anyone know if these configuration changes are supposed to affect the log files? Am I using this configuration parameter incorrectly?
Note that I have found a way to configure the logging severity using a logging.properties file, by calling:
LogManager.getLogManager().readConfiguration(EventDAOEJBImpl.class.getResourceAsStream("/logging.properties"));
However, this does not allow me to configure the application from the weblogic console. Is there a way to configure the logging severity using the weblogic console?

Configuring WLDF to recieve email Alerts in Case of Out of Memory Errors

Hi All,
I need help regarding configuring WLDF to receive email notifications in case there us an outofmemory or any other critical failure in the logs. I followed the documentation but i am not able to get it right. Do i need to write a seperate mailing program or just need to provide the email address in the console.
Any suggestion will be helpful,
Thanks,

WLDF in weblogic 10,3,5

Hi ,
Please some one help how to configure wldf 10.3.5 . is there is any sample script?
Thanks,

Hi,
For Email notification for stuck threads on your Server, you need to first create a Diagnostic
Module. Within this you have to configure the Watches and Notifications.
In this example, we are setting up a watch on the server log to look for the MaxStuckThread warning being reported. We do this be setting the Rule Expression to be equal to the message ID for this warning, when examining the output of the server log.
Within the notification, we can set up any type of notification, but in this example we are setting up an SMTP (mail notification), so that when the rule expression matches the mail notification is sent.
Below is the content of the Diagnostic_module.xml file created after completing the above tasks:
<?xml version='1.0' encoding='UTF-8'?>

Issue with WLDF Console extension displaying Instrumentation details

Hi,
I have enabled WLSDF Console extension on WLS9.1.
I am able to monitor weblogic metric data but when I enable instrumentation in my diagnostic module WLDF console displays server state as Unknown.
I am not able to monitor any metric data or request details after enabling instrumentation.
I have enabled DEBUG for diagnostic package and I can see diagnostic data getting collected in a server file store.But I am not able to see any details on WLDF dash board.
Has anyone experienced similar issue ?
Thanks & Regards,
Bhushan

Hi Bhushan,
Can you post your WLDF descriptor, and your config.xml? I'm not sure I can decipher what's going on based on the problem description.
Modifying or deploying a WLDF descriptor to a server should not affect the console extension behavior. Are there any error messages in the server log?
Are you actively graphing metrics in a DB configuration that are not displaying after this change?
Thanks,
Mike

[logging] Problems to configure logging rotation.

Hi,
I have an application .ear deployed in weblogic v10.3.1.0
This application use java.util.logging to write a log file.
 fh = new FileHandler(logFileName,0,1,true);
 fh.setFormatter(new XMLFormatter());
 logger.addHandler(fh);
FileHandler(String pattern, int limit, int count, boolean append)
pattern - the pattern for naming the output file
limit - the maximum number of bytes to write to any one file. If this is zero, then there is no limit. (Defaults to no limit).
count - the number of files to use
append - specifies append mode
http://www.javadocexamples.com/java/util/logging/java.util.logging.FileHandler.html
logFileName is dynamic with date formated like this yyyMMdd + ApplicationName + ".log"
This file is created but I have also yyyyMMddSEC.log.1, yyyyMMddSEC.log.2, yyyyMMddSEC.log.3,...
I DON'T WANT THESE FILES_, that's why I put limit to 0, count to 1 and append to true.
This code works without jdev/weblogic but has not effect in weblogic.
Q1. Why?
So I go to Weblogic console: Domain Structure-> DefaultDomain->Logging
Log file name: logs/DefaultDomain.log
Rotation type: None
NONE
Messages accumulate in a single file.
You must erase the contents of the file when the size is too large.
Note that WebLogic Server sets a threshold size limit of 500 MB before it forces a hard rotation to prevent excessive log file growth.
But it doesn't work, Weblogic continue to create log files like this *<filename>.log.<n>*
Q2. Why?
I have also created weblogic.xml in ViewControler/WEB-INF
thanks to this documentation:
http://download.oracle.com/docs/cd/E13222_01/wls/docs103/webapp/weblogic_xml.html#wp1063199
but it doesn't work...again.
Q3. Why?
Q4. If I want applications manage themselves their log, how to deactivate the logging handler in weblogic (LogFileMBean?)
Thanks for your help.

WebLogic Server 10.0 Logging Configuration

Does anyone know if there is a way to update / modify / configure the logging for WebLogic Server logs to make the time stamp on log entries go out to milliseconds? Right now log entries only have precision to seconds, but we want and need to see them out to the millisecond.
We are well aware that log4j is an option, but that seems to require coding and we were hoping to avoid that given our only additional need was precision out to milliseconds.
Thanks.

WLDF - Instrumentation for EJB call statistics

Hello,
I'm new with Weblogic and I'm looking for stats concerning my ejbs. I'm using weblogic 10.3.
With JMX I have only found data concerning EJB pool size but no statistics (like execution time)
thus, I'm looking for instrumentation using WLDF to see if it is possible to get the execution time of an EJB method.
Firstly, I try to instrument a method, i've used the following weblogic-diagnostic.xml file.
<wldf-resource xmlns="http://www.bea.com/ns/weblogic/90/diagnostics">
 <instrumentation>
 <enabled>true</enabled>
 <include>com.gemalto.*</include>
 <wldf-instrumentation-monitor>
 <name>ConfigurationManagerBean_Monitor</name>
<enabled>true</enabled>
 <action>DisplayArgumentsAction</action>
<location-type>before</location-type>
<pointcut>execution(public * com.xxx.* get*(...))</pointcut>
 </wldf-instrumentation-monitor>
 </instrumentation>
</wldf-resource>
When I put this file into my MEAT-INF EAR, the deploying is OK but I'cant see nothing into WLDF console extension ?
Could you please explain me a little bit how to configure correctly my instrumentation ?
Thank you a lot.
C.

When I put this file into my MEAT-INF EAR, the deploying is OK but I'cant see nothing into WLDF console extension ?Are there events in the WLDF Archive for the deployed monitor? Have you enabled Instrumentation through a WLDF System Resource targeted to the server?
In order to view instrumentation data through the console extension,
- the WLDF DyeInjection monitor needs to be deployed through the WLDF SystemResouce at server scope as well.
- the application monitors must be of the "Around" type with the TraceElapsedTimeAction assigned to them
Then the console extension can build a call-tree of known requests that have passed through the server, based on each request's Diagnostic Context ID.
If you truly want to view information from the DisplayArgumentsAction, you will need to view the data stored in the WLDF Archive using the WLS Console, or WLST. In the Console, you can view the data by navigating to Diagnostic Modules -> Logs and selecting the EventsDataArchive "log". On the resulting page you can customize your views (the default view only shows you the last 5 minutes of data in the archive, I believe).
Using WLST you can use the exportDiagnosticData (offline) or exportDiagnosticDataFromServer (online) functions. See the WLST help on these functions for details on how to use them.

Appreciate your comments

Do you see any further nested exceptions OR errors in the log file.
Considering that the same WLS-JDK combination works on one machine and does not work on another machine, it indicates an environmental issue.
"However installed Web Logic 10.3.6 (64bit) and Java JDK 1.6.0_31 (64bit) on that same server. The web page cannot be displayed....

I am suspecting if it has to do anything with the native libraries being loaded JAVA_LIB_PATH.
Please review the server log file again for identifying differences in LIB_PATH or PATH or any messages saying "Unable to load native.. performance pack.."

Weblogic 9.0 WLDF Instrumentation

I am tryin to understand WLDF Instrumentation capabilities by looking at MedRecServer --> MedRecWLDF--> Instrumentation --> DyeInjection configuration.
It loooks like that DyeInjection monitor sets DiagnosticContext when request enters into the weblogic server with following properties.
ADDR1=127.0.0.1
USER1=[email protected]
I have executed request with above properties in medrec application.
What I am trying to find is How to access diagnostic context/data/information as result of the execution of DyeInjection monitor ?
Thank you,
-Jayesh

Hi Jayesh,
Instrumentation ("event") data is stored in the WLDF archive, in a binary store. This data can be accessed viewed via the WLS Console, via the WLST "exportDiagnosticData" command, and programmatically via the WLDF Accessor APIs.
To view data via the console, log into the console and choose
Diagnostics -> Log Files
select the "EventsDataArchive" radio button, and click the "View" button. You can also specify custom query parameters via the "Customize this table" link.
See
http://e-docs.bea.com/wls/docs90/wldf_configuring/access_diag_data.html#1099608
for info on accessing WLDF data,

TIA

A very nice way to accomplish this: From within the extension project (in JDev), set the project properties for remote debugging (Run/Debug panel of the project settings dialog, Edit the Default configuration). From a command line execute jdev.exe -ojvm -debug. The dialog that comes up inside of JDev will let you choose localhost. The first instance of JDev will be debugging the one that's about to open.

SAP message Log

Does SAP maintain log of all the messages displayed on screen using MESSAGE statement?
We are investigating a problem and want to see the messages displayed by SAP during the time when problem occured.

We have custom development for picking and confirmation. Last week we found that in some deliveries there is difference in delivered quantity and packed quantity.
Custom development is calling sap-standard FMs. Problem occurs randomly, roughly 10 deliveries in a week has this problem.
We are still trying to investigate the reason that is causing the problem.
Custom program does display the message to user if FM raise any message. We asked user of they are getting any message while picking, and if they are ignoring it.
They just confirmed that they are getting message 'Packing Not Possible Since there is no Quantity to be Packed' and they did ignored this.
