OHS calls backend weblogic application/services and high response time seen only in the mod_weblogic plugin

Imran_Jamadar — Wed, 24 Mar 2021 17:58:08 GMT

We are seeing high response time on mod_weblogic plugin and same is popping up even in response time hotspots. OHS forwards request to -> weblogic backend application, once the request reaches backend the response from backend is fast, Much of the time is spent in mod_weblogic plugin which is listed as other and is shown as self-time for mod_weblogic

I even checked for static content and this issue is coming even for simple image fetch. There are many idle web server threads and no issues observed on resource exhaustion.

Attaching both scenarios for reference . Even raised support ticket but still no positive and concrete response

Hi Imran,
I just moved your question from the AppMon & UEM forum, which is one of our end-of-support classic products. Now you are in the right spot and I hope you get an answer soon.
Thx, Kurt

I belive this is a case of further investigation on your OHS in the weblogic module on OHS. Since based on the screenshots the requests to backend are executed at the end of the time of weblogic on the second example. Maybe a DNS issue?

I don't have any particular experience with OHS, but I guess there ist definitely an option for increased log verbosity of the mod_weblogic that may reveal the cause.
