Hello?
My JENNIFER main screen(dashboard) only displays certain layers.
At present, I am performing tests by interconnecting Jennifer(4.0.5.3) and Oracle(11g),
I installed tomcat for three services(7900 ~ 7902) in the same server.
Among three services, only startPort 7900 does not show some items and data including the real time system CPU utilization.
When I switched the ports for the normal and the abnormal services, I discovered the following.
When I switched to 7901, the abnormal service became normal. When I switched to 7900, the normal service only showed certain layers just like I mentioned above.
Since only port 7900 has the problem, what should I check for troubleshooting?
The network settings for ports 7900 ~ 7902 are same and other servers with the same network setting are operating properly. In addition, I saw the same problem happening when I terminated the Oracle service and performed tests with the Derby DB.
I was told that depending on the start port, a certain layer is called.
If there is a problem with the 7900 port setting, then why does it affect certain layers only, not the entire layers?
The following is the changes made in the server and the agent.
Screen captures are attached. – normal : service1(7900) / abnormal : service2(7901)
I am looking forward to your reply.

? Server
UDP Port
Service1 : 6901 ~ 6903 / service 2 : 16901 ~ 16903
TCP Port
Service1 : 6701 / service2 : 6702
ROOT.xml
Oracle interconnections, only the accounts are configured separately.

? Agent
– agent_name / tcp port (7750~7751) / udp_server_host/ udp related port.

Thank you!
Have a good day!

If you are unable to check the CPU utilization or the number of visitors, you can change the layout. The option exists in the JENNIFER server. Please, upload the properties files for the server.

The properties file you requested is attached.
(Normal : 7901_jennifer.properties / Abnormal :7900_jennifer.properties)
In the file, the udp_server_host option value was deleted for the security reason.

Although JENNIFER supports JAVA, in a non-commonly-used OS environment,(zOS), the system resource information can’t be collected.
In this case, if you set ui_dashboard_system_resource to false, then the dashboard will not show the CPU graphs.
In a communication demon or ESB system, a client is not a web browser but it is another system instead, so there can’t be any visitors or simultaneous users. When monitoring such systems, you need to remove unnecessary graphs in the dashboard by using the option, ui_dashboard_user=false.
The attached screen capture shows a case where both the options are set to false.

The problem persists as I check it again.
I have a question about the version of JENNIFER called from the Java console screen, which seems be different in each case. When the web page is called successfully, JENNIFER 4.0 is called. But in case of abnormal services, JENNIFER 4.5 is called..
I installed version 4.0 after using version 4.5 in the past.
Now, both the server and the agent are version 4.0 and the property values are also for version 4.0.
However, where does the version 4.5 information called in the Java console come from?
I attached the screen capture for your reference.
I am looking forward to your reply.

Thanks in advance.

Try to delete the cache for your client PC.
Drag your mouse cursor to the client’s JVM heap display area in the upper right corner of the JENNIFER screen and click your left and right mouse buttons. You will see the temporary file delete menu. Select to delete the temp files and restart the browser before checking it again.

The same problem persists. Is there any other way to fix this problem?

I deleted the temporary files in the JAVA control panel. Now the problem is gone.
Thank you.
Have a good day.
