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

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.

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.
${DOMAIN_HOME}/WLSDM/logs/wlsdm.log

Hi,

This bug has fixed in v3.9.1 WLSDM version.

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,

You can select any range by using date field. But the maximum backward range is the WLSDM monitoring start time.

Kind regards.

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…

Hi,

The WLSDM and the WL-OPC have their own data-archive mechanism.

For the WLSDM, default data archive range is 90 days, and for the WL-OPC, default data archive range is 365 days.

You can find the settings below.

Kind regards.

WLSDM: Configuration > WLSDM System Settings > system.archive

WL-OPC: Administration > System Settings > Notification

Hi,

Non-adminstrator users not allowed for administrative operations by default as below screenshots.

Metric configuration for monitor user:

Metric configuration for adminstrator user:

File explorer for monitor user:

You can change access restriction configuration in “WLSDM System Settings > system.authorization” page.

Default value is OFF in “system.authorization.page.access.fileexplorer.allgroups” feature. It means only administrators can access to “file explorer”. If you turn on this feature, you must set access path for non-adminstrator users then non-adminstrator users only can access the path(s).

You can restrict log viewer access configuration via “system.authorization.page.access.logviewer”. Default value is on, it means all users can access log viewer, if you turn off this feature, non-adminstrator users will not able to access logviewer.

Hi Jeba,

If you want to see File/Socket events you should increase your WLDF Diagnostic volume on WebLogic

Go to “Servers > $ManageServerName > General (tab)” page and set “Diagnostic Volume” high. Then you are able to see file read/write events.

Note: This option means additional overhead on your managedservers; just activate only one managedserver which file read/write monitoring is important.

Regards.

Hi,
this problem only exists on Chrome browser. If your Chrome updated recently, this can be occur. It’s a Chrome issue and we’ve reported.

On WLSDM console refresh page with “CTRL + R” or “CTRL + F5” then it will be resolved.

Hi,

You can’t call the stored WLST scripts from the scheduler module.

And you need a shell script (custom action) to run an external WLST script from the scheduler module.

Kind regards.

Hi,

Are you sure you have created HTTP transactions for the relevant managed server? Remember you need to create real traffic to exceed 8kb buffer size for the response times monitoring. So, at least there must be +100 request after managed server restart.

Are you sure you have selected the right managed server on the “Response Times” page? (Please take below screen capture as a reference)

2..jpg

Go to “Configuration > Monitoring & Diagnostics > Response Times (tab)” page and check the status. Is there any server needs to be restarted?

Kind Regards…

Please try registering the domain by using the “overwrite” and retry delete domain.
