I'm trying to understand what is the third parameter in my /var/log/messages file. For example:
$ logger test
$ grep test /var/log/messages
May 20 15:32:57 hostname myusername: test
Sometimes myusername is a process name, like httpd. But what's driving me crazy is that there are some lines that contain nonexistent user/daemon
May 20 15:32:57 hostname weirdname: some-http-request-here
What is weirdname? It's not in my /etc/passwd, not in my /etc/group, and is not a daemon/program.
