I am in the need to document and put into a logical diagram (flowchart) of what our Linux (Debian) servers do.
I need to produced the process dependencies that help the interaction of the running applications.
Meaning the way Apache works with MySql (ports, system users, IPs, MAC, etc) and how it flows in the Intranet.
I want to document the versions of the applications like for Apache, MySql. Get as much detail as possible that help us troubleshoot or keep development.
I am trying to figure out with a few commands I find on the web like htop.
Suggestions are much needed to get this done as professional as possible.
