Requester: @bibarrav

Hi guys!,
Is possible to have a CUSTOM LOGs or something like that to monitor various logs files generated dinamically on some folder in the Web Logic Server? In some cases we use these kind of files to register detailed transaction procesing to have a better understanding of application test cases under the hook, obviouslly in a DevTest Env.
Great work BTW!!
Regards

Hi Bibarraw,

Thank you for your supportive comments. Custom log monitoring and every kind of log/text file management is available on WLSDM. Please check below documents and tech blog posts;

@wlcommunityusers said in WLSDM dasboard restriction for read only mode:

Requester: @jorfergo

Hello. We are were interesting in have a “public” dashboard, where we can custom the metric to insert, and do only accesible this dashboard for other public (operators, management, etc). It will be needed that this dasboard only be accesible in read only mode, to block modifications/actions by the consumers.

Jorge

Hi Jorge,
We are working on your issue. We have one last question;
How about login? Are these public dashboards should be restricted with logged in or not according to your requirement?

@wlcommunityusers said in WLSDM could show the composites list for SOA domain?:

Hi All,
I believe that it will be very useful if WLSDM could show the composites for SOA domains which became failed after restart the managed servers.
Thanks

Hi Ozhan,
We have a “Composite List” page and maybe we can track the status of Composites periodically. It is a good case to monitor failed SOA composites.

We have another option after v3.2.2 which is the scheduler. Maybe setting up a scheduled job can do this. We’ll be working on it and let you know with a technical reply.

@wlcommunityusers said in Export WLSDM dashboards to another weblogic domain:

Requester: @vanrussell_nl
We have created our own custom WebLogic dashboards on WLSDM console; is it possible to export these WLSDM dashboards to another weblogic domain? This feature would be very helpful to us; because we setup WLSDM usually in our operations.

Hi, Thank you.

We will have an export feature on the next official release. Will try to add export custom dashboards for WebLogic monitoring.
Regards…

@wlcommunityusers said in WLSDM WebLogic .out and .log monitoring & generate notifications:

@vanrussell_nl

Hi,
Is there any plan to support WebLogic out logs monitoring? It would be great if we have the options to monitor WebLogic out logs and generate notifications

As we discussed before, you can redirect OUT logs to the WebLogic server logs then you can monitor OUT and ERR logs.

On the other hands; we have implemented the CUSTOM LOG MONITORING feature for the next release. It’s possible to monitor every kind of log file on the Oracle WebLogic application server.

@wlcommunityusers said in IBM JDK (AIX) Java arguments for the WLSDM agent:

Requester: @dirk-nachbar
Hi WLSDM Team,
I’ve a request for providing the required Java Arguments for the WLSDM agent under IBM JDK (AIX) within your Installation Document Thanks in advance.

Hi Dirk,
These JFR (Java Fligh Recorder) arguments are valid from JDK 1.7_040 version. You can check this out: https://publib.boulder.ibm.com/httpserv/cookbook/Java-Java_Profilers.html (See “Java Mission Control (Formerly JRockit Mission Control)” section)

If your IBM-AIX environment works on Java 1.6.xx, there is no need to add these JFR parameters. Only add “-javaagent:/path/to/wlsdm_agent.jar -Dwlsdm.agent.logger.level=INFO” this means you are NOT able to monitor backend operations. But all the rest will work properly.
By the way, we are going to update our installation document by adding these additional information. Thank you for your contributions.

@dirk.nachbar On the other hand, we have released a new v2.5.2 and it covers the OSB module inline. Also update the website, blog site and community site 🙂 For your information…

@wlcommunityusers

Hi,

Please follow screenshot’s steps and set the threshold as below.

@wlcommunityusers said in Daily OSB reports for ProxyService performance:

Requester: @vanrussell_nl

Hi, We’re using WLSDM OSB Module v.2.3.1. When the official OSB module will release? Is it possible to see OSB Daily reports just as SOA module?

We are going to release new 2.5.2 version three weeks later. In this version, WLSDM-OSB Module will be released officially.
It will covers Oracle Service Bus (OSB) Daily Reports just as you mentioned. You’re going to able to get daily OSB reports for ProxyService performance and availability. FYI.

Hi,

WLSDM cron takes several minutes to return cycle. Reduce some minutes, Example 1430 rather then 1440.

@wlcommunityusers said in Create custom back-end (JDBC, EJB, Webservice… Etc.) dashboard:

Requester: @tom-pinto

Just as JMX metric dashboards; is it possible to create custom back-end (JDBC, EJB, Webservice… Etc.) dashboard? It would be great to add this feature…

We’re currently working on this and it will be possible to create unlimited back-end dashboards. Another good news: Additional back-end EVENTs are coming 😊 Especially wait for Socket R/W charts…

Hi,

Did you upgrade the domain? Your latest screenshot says your WLSDM v3.7.2 but WL-OPC says WLSDM v3.9.2.

You can follow the below provided solution.

Check two way access between WL-OPC and WLSDM
WLSDMHostname$ telnet OPCHostname 8080
WL-OPCHostname$ telnet WLSDMHostname 7001 Open problematic domain’s wlsdm_agent.jar with winrar and check WLSDM-version in “META-INF> MANIFEST.MF” file. If there is old version just replace wlsdm_agent.jar with the new version in $DOMAIN_HOME\wlsdm_agent\ Unregister problematic WLSDM domain from WL-OPC Complete WLSDM installation wizard without WL-OPC registration Register WLSDM domain to WL-OPC in WL-OPC “Administration> WL Domain” page. If the problem is not resolved please send us $WL-OPC_HOME\bin\WLOPC\logs with the zip file

Kind regards.

Hi,

On the other hand, I’m trying to configure a script to be executed once I have a stuck thread alarm.
Is it possible to do that?

Hi,

SOA default dashboards are contains complete SOA monitoring and they are sufficient for monitoring SOA performance.

You can check https://medium.com/wlsdmforweblogic WLSDM Medium blog posts by WLSDM team and customer experiences.

Hi,

You can change the JFR repository directory using the following JVM option:
WLSDM must delete those temp files which is older than two days (48 hours).

-XX:FlightRecorderOptions=repository=WLSDM/temp/JFR ( see: https://wlsdm.com/docs/#VI.Installation )

If you choose not to define (or remove) this JVM option, by default the files will be stored under the operating system temporary directory.

For more information see: https://docs.oracle.com/javase/8/docs/technotes/tools/unix/java.html
repository.png

Also, jfr files are static profiling files, not library files. You can delete them safely even runtime.

For the second question: You can achieve that using the “Downtime” feature:

1 – Go to WLSDM console / “Monitoring & Diagnostics” page.

schedule.png

2 – Open the page operations and click the “New Scheduled Job / Downtime”
newschedule.png

3 – Configure the downtime and click save.

At this point, you have two action option:
1 – Stop all notifications but keep monitoring
2 – Stop all monitoring

Oh, that’s lovely, thank you very much!
Have installed 3.9.1 in out sandbox environment after receiving the newsletter last week, will give this a shot right away!

Hi Can,

This error is the wrong path for java in setenv.properties file configuration.
Because in Linux alternative link using for java path.
If you are using this command in terminal. “echo $JAVA_HOME” then it gives a true java path.
ex: echo $JAVA_HOME --> /usr/lib/java/jdk1.8.0_201
In setenv.properties file JAVA_HOME line change with your full java path.

Then you can start WL-OPC.

Regards.

Hi Karim,

You have Out of Memory error while opening this managed server. Please check below error in your managed server log.

You had better tune and optimize your WebLogic environment or increase server memory.

Hi,

You can follow WLSDM installation instructions in https://wlsdm.com/docs/#IV.Installation page.

There are notes as below for installation:

I. Known Issue: After the complete WLSDM installation if the “Smart Dashboards > JVM System Resources” page is not working well and does not show the metric values properly then add “-Djavax.management.builder.initial=weblogic.management.jmx.mbeanserver.WLSMBeanServerBuilder” JVM argument to the relevant Managed Server(s) and restart the server(s).
II. Do not install agents for whole servers. same cluster or same machine not needed WLSDM agent (as below screenshot).
III. Care “with Nodemanager” and “without Nodemanager” parameter step in wlsdm installation document then use one of them which are you using.

Hi,

It looks like SMTP Server that you are using requires authentication.
535 Authentication required com.sun.mail.smtp.SMTPSendFailedException: 535 Authentication required

Please make sure the SMTP username and password are set on the WLSDM.

After that, you can check the setting by using the “Test Email Settings” button under the page operations dropdown menu.

Hi,

OPC default port is 8080, When you need to register domain to OPC first of all; check firewall rules for below ports with telnet.

OPC and agent both are communicating each other you need mutual firewall request.

From: ${WLSDM_AGENT’S_IP}
To: ${OPC_SERVER’S_IP:8080}

From: ${OPC_SERVER’S_IP}
To: ${WLSDM_AGENT’S_IP:WEBLOGIC_ADMIN_PORT}

Hi,

Sometimes WebLogic blocks the direct access to the Java Native MBean Server from inside it for various reasons.
And that affects some modules functionality.

Please add the following startup argument to your managed server.

İf it does not solve the problem, please zip and send the “wlsdm.log” file to us for the detailed examination.
