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.
You create new Devops MBean and new Dashbaord in WLSDM as below screnshots.
Also please check suggested blog posts:

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

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.
Regards.
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.
Regards.
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}
Regards..
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.
${DOMAIN_HOME}/WLSDM/logs/wlsdm.log
https://wlsdm.com/docs/#IV.Installation
Regards.
You can analyze high CPU consumers and backend events in the "possible root cause page"/ "thread analyze page". This page gives you important tips for errors/hogger/stuck threads.
You need to have a valid license to monitor these pages.
how can I know through the wlsm that queue mq is currently affecting the managed nodes?
Go to “Configuration > Metric Settings & JMX MBean Browser” then click “JMX MBean Browser (+Add New)” button for navigate below modal window then create new JMX MBean for JMS metrics in 8 steps.
how to know on which node managed I have agent configured from the wlsdm?
You can check which managed server has WLSDM agents in “Operational Tools & Utils > Monitor WLSDM Agents” page; but there is no need to WLSDM agent to monitor stuck threads.
because the stuck thread dashboard does not appear on the path: Smart Dashboards Servers, but I do see hoggingthreadcount information
• Check dashboard count for “StuckThreadCount” metric in “MBean Browser” pool it must be select at least 1 dashboard..
• If there is no “StuckThreadCount” metric; you must add from “JMX MBean Browser” button.
Hi,
We have one more question: is there a chance to be wlsdm jar or war file is in the WebLogic classpath.
We are asking that because, the below log generally indicates that issue.
java.sql.SQLException: Failed to start database 'WLSDM/db' with class loader PolicyClassLoader 'weblogic-launcher' @50d0686 {file:/u01/app/oracle/product/fmw/wlserver/server/lib/weblogic-launcher.jar file:/u01/app/oracle/product/fmw/wlserver/server/lib/pcl2.jar ... (642 more)}, see the next exception for details.
If it is not, the reason is may the database corruption you should try the fresh installation.
https://wlsdm.com/docs/README#VII.Upgrade&Reinstall&Uninstall
SOLUTION:
The agent.jar was in the lib folder. The lib folder was on classpath.
I repaced the agent.jar. This solved the issue.
Thanks a lot.
Hi,
I am happy that you are able to monitor your backend datasource JDBC monitoring. Yes, you can monitor all your datasources in the same dashboard.
Other APM tools injects runtime codes to your codes which creates a lot of overhead on your JVM instances. WLSDM uses native method and that’s why we call “native WebLogic monitoring”.
On the other hand; please follow “Generic DevOps MBean” tutorials and build your own dashboards and automate your WebLogic management.
Kind Regards...
Hi,
Thanks for your kind support.
JMS Servers resources added successfully.
Hello,
When we skip the monitoring of DataSource and JMS server, setup finishes successfull.
Regards.
