Webagents & Several httpds on a server
Hello All!
I am trying to install a webserver agent on a Apache webserver with 3 httpd's. The question is if I need to add several names for the web agent (according the system profile) on the file dtwsagent.ini.?
The instructions says that I need a line with the name of the agent here. However, if I have 3 httpds, should I have as well 3 different agents to monitor each one by separate?
Not so sure how this is handled, since the httpd will have only an extra line with /libdtagent.so. I don't see how Dynatrace will link the httpd to each agent here.
Maybe I am missing something.
Thank you for the help!
Hi Ageo,
Just put a single name in the dtwsagent.ini. The name will map to the master agent and there will be a child agent under it in the agent overview for each child with a unique name (I think it adds the PID to the end ). Just make sure you have a "starts with" rule in your agent mapping...
HTH,

Hi David!
Thank you for the suggestion. However, I think I didn't explain myself completely correct. What I mean with 3 httpds, 3 different processes running simultaneously, but different, not an instance of a master one. In short, each httpds will be attending different applications. That's why I was wondering if I need to create several dtwasgent.ini. What do you think ?
Thanks!
Hi Ageo,
The recommended way to do this is to install the Agent 3 times in separate directories, and reference each separately in the individual httpd.conf of your Apache instances.

Rick,
Thanks for confirming what I suspected was the correct answer! Since there is a one-to-one mapping between dtwsagent process and dtwsagent.ini, I assumed that was the necessary approach.

I think installation of the web server agent is required only once.
We install once and create copy of the install folder for additional web servers instances in the same host.

That was the old recommendation, but the full install is what I'm recommending now because we've added the Web Server Master Agent as a service in Unix/Linux systems and the appropriately parametrized init script gets created with each install. Does that make sense? See the doc (Web Server Agent Configuration) for what I'm referring to.
