How to detect if Camunda is running and on which port? How can i check all requests from client to Camunda?

I am on a new project, where previous developer developed and deployed Camunda processes, but did it (i think so) not very good and left and now he refuses to collaborate. It was working fine for some time after he left, but after server was reloaded it stopped and now we have 500 Status on some requests from client.

(I am sorry if i am asking not very smart questions and that there are too much questions, cause i have nearly couple of weeks to fix this problem, i have read some Camunda docs, but couldn’t find exact answers and i’ve never worked with Camunda before)

I have 3 options:

  1. Camunda isn’t running at all

  2. Camunda is running, but something is incorrect.

  3. It’s client app’s problem

I started to work on 1st problem and immediately got confused by other developer in my team. He says Camunda WebApps (Admin, Cockpit etc.) are running on port 8082 (we can access localhost:8082 with all WebApps) and Camunda Core should run on port 8080, but there’s nothing on this port, when starting Camunda.

As far as i know we start Camunda only with startup.bat or start-camunda.bat and it starts both Camunda Core and Camunda WebApps on the same port at the same time. So now question is to make sure, that i am right and Camunda IS in fact running and is running on the same port as WebApps.

  1. If Camunda is running we face second problem, which is i don’t know how to detect if the problem is on client or Camunda side. I’ve found 4 types of logs in server > apache-tomcat-… > logs folder:
  1. manager - empty
  2. host-manager - empty
  3. catalina - if i am right it logs Apache Tomcat server things
  4. local-host-access-log.txt - this is quite close to what i am looking for. There aer logs like 0:0:0:0:0:0:0:1 - - [04/May/2024:13:41:20 +0500] "POST /api/bpm/task/get-by-process-ins-id-list HTTP/1.1" 404 802. As far as i got it it’s also Tomcat’s logs and not Camunda’s logs. Where can i find them ? Also does this log say that Camunda is actually running ?

If You could answer even one of my questions i would be very very thankful!
