Hi,

WLSDM doesn’t support the multiple log files for log monitoring.

The current algorithm based on, “one log file, one search string” rule.

So, currently, there is no easy way to do this.

But we are going to report your request for the next WLSDM version.

Hi,

ProcessCPULoad metric values are sets between (zero) 0 and (one) 1 as “java.lang.Double” by the JVM.

So “1” means 100%.

To get an alert (for testing purpose), you should set the threshold value to less than “1”. eg. “0.01” (1%)

Hi,

We are not supporting multiple log files (types) for a query/monitoring.

So currently you should repeat the monitoring queries.

But, you can assign the query to multiple servers for the “ServerLog”, “stdOut”, “stdErr” and “Diagnostic Log” types.

Kind Regards…

Hi,

“[email protected]” is default sender (from) address for WLSDM and your mail client may not accept it.

To change sender address:

• Go to “Configuration > WLSDM System Settings” page
• Select the “mail.account” tab
• Edit the “mail.account.smtp.username” property (e.g. [email protected])

Test changes :
On “Configuration > WLSDM System Settings” page; open “Page Operations” menu and click “Test Email Settings” button

Hi,

The right side of equal char which is attributeValue must be only numeric values.Probably your script contains string and you need to trim string chars.

Also the first “/” should be replaced, too. Here is sample blog for your reference. One of our community user; used below script for doing it.

http://mathiassalgado.blogspot.com/2017/06/add-metric-options-to-devops-mbean-with-wlsdm-weblogic-console.html

script→ df -H | grep -vE ‘^Filesystem|tmpfs|media’ | awk ‘{ print $6"="$5}’ | sed ‘s/%//’ | sed ‘2s///ROOT/’ | sed ‘s///_/g’

I recommend filter the result set; it does not make sense to use every result for “df –h” . i.e. you /etc, /dev, proc, system… Only consider the mount points which relevant with WebLogic JVM processes.

Hi,

WLDF Query Language is not supporting in diagnostic log monitoring because diagnostic log monitoring is a special solution.

Firts of all, is strings connecting with “OR” or “AND” ?

If you are using“OR”, you must define two different search for two different defination.

If you are using “AND”, you can replace search string with exact defination.

You can search string as below.

Diagnostic log row: [ACTIVE].ExecuteThread: ‘2’ for queue: ‘weblogic.kernel.Default (self-tuning)’] [userId: ][APP: Service Bus Kernel] [partition-name: DOMAIN] [tenant-name: GLOBAL] [oracle.soa.tracking.InstanceId: 14216584] [oracle.soa.tracking.SCAEntityId: 10537] [oracle.soa.tracking.FaultId: 2252239] [FlowId: 0000Lu^vEciEoI04jz_Aio1PjgB80001jW] Outbound.B2BI/pipeline/vendor**/Unhandled error caught by system-level error handler: com.bea.wli.sb.pipeline.PipelineException: Service Unavailable**

Search string: “/Unhandled error caught by system-level error handler: com.bea.wli.sb.pipeline.PipelineException: Service Unavailable”

Hi,

Yo need to edit script according to your environment.

· http://community.wlsdm.com/topic/38/monitor-webservice-response-times-with-curl-alldetails-on-weblogic

Add soap-request.xml to server and replace à [email protected]/Users/admineer/u01/scripts.imac/curl.ws/soap-request.xml

Replace /Users/admineer/u01/scripts.imac/curl.ws/response.xml

Replace (Also add to server) “@/Users/admineer/u01/scripts.imac/curl.ws/curl-format.txt”

For testing below script the server must access the http://www.webservicex.net/globalweather.asmx URL. I am highly recommending test with an “inhouse” business Webservice. You need to reconfigure this according to your service.

Yes, everthing was just fine. If you want to remove buffer on WebLogic decrease the buffer size to “0” on “WebLogic console > $Server_Name > Logging > HTTP Logs > Advanced > Buffer Size” section.

@Ramanpreet_Singh

Hi Ramanpreet,
We are happy to solve your issues. Thank you for the affirmative report.
Always use $IP:$PORT/console/WLSDM direct URL for accessing WebLogic WLSDM console.

@Ramanpreet_Singh Hi,

Export/Import feature is used for WLSDM settings. Nothing related about WebLogic configuration.

i.e. If you configured SMTP settings on WLSDM; these values will come from export file or DevOps Mbeans and any other WLSDM configuration you have done.

Kind Regards…

Hi @Ramanpreet_Singh,

Currently, you cannot. But we will add this feature to next release.

Hi,

On the Back End Reporting, by default EJB and JDBC events are captured and alerted. This is useful. But there are options like File Read, File Write and Web Service calls on the Back End Reports. We enabled these options for the Managed Server but none of these events are captured or displayed in those reports. But while restarting the Managed Server, if we include this JVM option,
“-XX:FlightRecorderOptions=defaultrecording=true”
Then I am able see all those File Read and File Write events are displayed and alerted. After removing the JFR default recording, then no events are captured. Is there any option or config we need? The downside of keeping the defaultrecording ON is that the Managed Server generates the JFR recording and the disk space grows exponentially which we don’t want.

Thanks,
Jeba.

Hi Jeba,

We analyzed your WebLogic monitoring request again and here our solution offer.

Please remove “-XX:FlightRecorderOptions=defaultrecording=true”, you do not need this option while using WLSDM. If you still 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.

Keep your file and socket read/write definitions on WLSDM.

Restart your managed server (it is needed after JVM parameter removing).

This is the best setup for monitoring your file/socket events. By this configuration you will not face any disk problem. Because; WLSDM will take care of JFR files.

Regards…

Thank you so much. I will give it a try and let you know whether this works in our scenario or not. Thanks.

@Ramanpreet_Singh yes you can customize the subject.

Problem is resolved by adding username and removing password. Then the WLSDM email SMTP configurations has been setup successfully for WebLogic.

Log Monitoring cycle default value is 120 seconds. You can configure it from “Configuration > WLSDM System Settings” page’s “system.monitoring” tab, property as below. It effects back-end, loginspector and response times frequency. No problem until 60 seconds but we suggest 120 seconds for high transaction traffic.

Hi,
We analyzed the problem with futher investigation and logs; that realized it is because of getting below error on WebLogic:

Request-URI Too Long The requested URL's length exceeds the capacity limit for this server.

Cause:
Accesing to WebLogic WLSDM console through a webserver (OHS, Apache… etc.) can cause above error while at the last step on WLSDM wizard screen when clicking on save button.

Solution:
Accessing WebLogic WLSDM wizard console directly (bypassing webserver redirection) will solve the problem. We recommend not to use Webserver proxy while setting up WLSDM wizard at first. After the wizard completion you can use webserver proxy freely.

Webservers have limitations about posting data bacause of security issues. The limit can be increased on the configuration files.

Kind Regards…

Hi maas,

Thank you for bug report. We noticed that problem and we will work on it to fix. Problem will be resolved at the next WLSDM release.

Hi maas,

Thank you for bug report.

This bug is reported before and we have fixed the problem.

Hi han,

This bug is fixed. if you are using any release of v2, please upgrade your WLSDM product to v3. And don’t worry you will not lost any data.

Hi Mathias,

Thank you for bug report.We noticed that problem and we will work on it to fix. Problem will be resolved at the next WLSDM release.

Hi,

Dashboard pages stores only last 24 hours data.

Older data: If the store data is active for the relevant metrics, you can find it on the “Reports> Metric Reports” page.

Thank you.

Hi,

We are supporting upgrade from 2.5.2 to 3.1.1.
Consider upgrade steps then your collected data will be kept and you won’t lost any data. But please take a back-up of WLSDM runtime folder which is located under $DOMAIN_HOME/WLSDM while your admin server is shut down.

Hi,

We are not generating JFR files under /tmp folder. WebLogic does this and we’re using the output. So, if you want to redirect to custom folder please use below settings and let us know the result.

Navigate to Enviroment > Server > Server Start. In “Arguments”, add: “-XX:FlightRecorderOptions=repository=/path/to/tmp/” JVM flags then restart WebLogic managed server(s)

We have Thread Dump action. Just activate ThreadDump action for Hoggers or Stuck metrics and then analyze thread dumps by using “Thread Dump Analyser”. If your Administrator good enough you can write your own scripts for detecting deadlocks on JVM threads.

Normally, WLSDM stores 24 hours data storage for MBeans and backend usage by default. But, all chart values can be stored on WLSDM database by turning it on. You can turn on “Store Data” for every data while setting up WLSDM wizard. After the installation, if you have not turned on “store date”, you need to open them by one by. Good news, you can sort them all on "
• Configuration
• > JMX MBean Metric Browser & Settings” page by sorting “Store Data” column. Just follow notifications on relevant notifications page. They’re stored for three months. Remember we have PURGE and ARCHIVE modules. You do not need to operation your monitoring console. It does everything for you.

Thank you for your interest. We trust our product very much and we thought every detail for WLSDM.

Here our comments;

First of all, your domain is really big and massive. But, we it is for sure we can handle it.

1 - For my experience what make the difference is collecting data… In order to monitoring historic information anda data (this help me in troubleshooting)
Yes, especially this size of domain is very hard to monitor. If you have any unused server, datasource, JMS definion please delete all, after that fresh resinstall WLSDM and do not track unused apps, servers, deployments… etc.
Historical data would be very useful for your problem troubleshooting. Especially, check notification pages.

2 - About deployments table your dashboard use to list applciation status in evey servers of my cluster and it is a little bit redundat
We have asynchronous backend health feature on health dashboard. Could you please enable it and let us know the result? (Go to Health Dashboard page, > Page Operations Menu> Switch the below button to ON)

save.jpg

By the way, we have JMX/t3 timeout on system.WLSDM tab at System Settings page. If your domain is not responsive has its own problem, we are cutting the request because of keeping WebLogic domain healthy. It’s default value is about 5sec. That’s why you can see the health status conflicts.

We support shell and batch (.sh and .bat/.cmd) OS script execution for custom metric actions. You can trigger any python/jython/wlst script by using WLSDM WebLogic console. We do not support script scheduling because of DevOps support. Scripts triggering is fully parametrical and can be assign to any specific MBean threshold.

Thanks for this wonderfull question !
Unlimited custom actions can be added on "Configuration > User Defined Metric Actions” page.

Here is a tutorial about adding custom actions for your reference: http://www.wlsdm.com/tutorials/advanced-weblogic-monitoring-develop-jmx-mbeans-and-automate-with-wlsdm-metric-actions.php

WLSDM console runs under WebLogic /console context path. And we’re using default WebLogic security realm. The configuration and important pages on WLSDM console is only accessible for Administrators global role. So, a user which has Monitor global role, only able to see only monitoring pages on WLSDM console. In this case, What kind of requirement do you have for the custom access for accessing WLSDM console.

When we did the webex session we had seen that you are able to login WLSDM console. This situation is something about Webserver. We need to sort out this plain-text problem. Which web server are you using for the redirection for the WebLogic /console redirection? Your web server serving WLSDM console somehow as plain-text instead html. It could be something about mime-type. Could you please check this out and let me see the result? http://stackoverflow.com/questions/9142117/pages-are-displaying-plain-text-instead-of-html
