Apache webserver

Hello,

Is my assumption correct that an apache webserver can only be used as an entry point services?

In other words, when a service calls a webrequest on a Apache webserver the "purepath" stops?

No, all depends on the Apache configuration - what Apache (or any other webserver) servers for a particular request.

For example if you have PHP running the PurePath will follow to PHP. If you have some custom module serving your requests the PurePath will stop as it probably won't be a supported technology.
If you have Apache in reverse proxy configuration, the PurePaths will follow to the backend service.

Hi Julius,

Thx, it is just a "regular webserver" where end users connect. So a webrequest from a with agent installed host should be recognized?

(so a service is used not a browser)

Definitely if there is oneagent on the apache host and the apache has been instrumented. Do you see any services on your apache process group?

Process group:

This is the API server, 4 of the 14 Services are apache webserver http

And the application with the 4 apache web servers

The Apache on the last screen is not apache http server but (probably) Apache Tomcat.

Yep, but the apache webservers are part of the dark blue boxes and talking to the Tomcat.

FYI in the same environment I see that the same, but without the apache webserver so communicating direct to a tomcat has no issue's

Can you post a screenshot of service flow? A screenshot of purepath? And how is the apache HTTP Server configured? Just forwarding requests to Tomcats? How do you expect the serviceflow / purepath to look like?

Based on your description it seems the Service flow is IIS -> Apache HTTP Server -> Apache Tomcat.
Based on the information above I don't see any issues.
Maybe the PurePaths you are looking to really are served at the Apache HTTP Server (caching?)

Found it, I hope,

IIS -> Apache HTTP Server -> Apache Tomcat

is

IIS->proxy->Apache HTTP Server -> Apache Tomcat

So the proxy must be "terminating" the purepath?

Julius_Loman

Yes, depending on what is the proxy in the chain it might be filtering HTTP headers added by Dynatrace.
A screenshot of service flow and purepath will bring some light into this.
