Virtualized IP address / 127.0.0.1 not working for web server agent
Hello everyone,
I run into a problem when starting a local web server (XAMPP) on a Citrix system with virtualized IP addresses together with the dtwsagent module. The agent inside the web server tries to send data to its peer service over 127.0.0.1, but the peer is listening on a virtual local ip other than that. I confirmed this behavior by turning on detailed logging information for the web server agent.
Is it possible to configure the local ip the web server agent uses to connect to its peer service or does some other workaround exist?
Best regards
Stefan
Hi. Are you talking about the dynaTrace Web Server Agent or the Module that gets loaded into Apache? Can you post the log file you are looking at?
I assume you talk about the web server agent. This agent gets the connection information from dtwsagent.ini. You can just change the collector addreses from 127.0.0.1 to any IP that will work for you and then restart the dynaTrace Web Server Agent Service

Hi Andi,
the web server agent successfully connects to the collector (I can see this in the dynaTrace Client), but the Apache module cannot connect to the web server agent (peer service) because I cannot configure the IP, just the port. From the Apache module log (increased debug level) I can see that it tries to connect to its "peer service" at 127.0.0.1:<portOfWebServerAgent>.
I can send you the log on Monday, but if you have any ideas beforehand, please let me know.

PS. I assumed that the Apache module gets its connection information from the dtwsagent.ini as well, please correct me if I am wrong.
Can you tell me which dT version you are using?
And yes - you are correct - it gets the port configuration from dtwsagent.ini. We first try localhost. Starting with dT 6.1 we then also test 127.0.0.1. Its not configurable to use a different IP. In your case I assume localhost gets resolved with 127.0.0.1. If that doesnt work for your environment you can change that in your hosts file on your windows box and specify a differnt IP for localhost
Please give this a try
