How to instrument multiple apache httpd worker processes
In one of our application the web server is creating multiple httpd_worker processes and looks like dynatrace is monitoring only one of those.
For a child web server agent it is not possible to map the agent to a process using PID so we are not able to find the right process of the agent.
We used top process monitor to find who is consuming CPU other than the monitored process during tests. We could find 4 httpd_worker processes consuming cpu and is higher than CPU usage reported by the web server agent.

Hi Sreerag
If you put the LoadModule statement in your httpd.conf our agent should be loaded into every instance of your worker processes. Is it possible that your multiple httpd worker processes use different httpd.conf files where not all of them have the LoadModule statement included?

Thanks for the reply Andi.
I thought the say and i'm going to double check with the app team on the httpd.conf file.
