Hi Karim,

Issues Faced While Configuring wlsdm_agent.jar

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.

WLSDM- SMTP Mail not working

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.

FW Ports Agents to WL-OPC Server

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}

WLSDM Agents Not Monitoring Error

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

StuckThreadCount Dashboard Not Visible and Other WLSDM Questions

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.
1.jpg

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.

Issue in wlsdm - Smart Dashboards > Servers

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.

Thanks a lot.

WLSDM Backend JDBC Getting Any Data Populated

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.

WLSDM log viewer line count

Hi,

WLSDM log viewer line limit is 1000 but you can search any string and find searched string where line is located in whole log file via “text filter”.

There is another way to view log files via WLSDM file explorer. Go to “Operational Tools & Utils -> File Explorer” pick “.log” file then click view button (max 1 mb view size). Also you can download log file to your local environment via file explorer.

Kind Regards..
