exiwhat - Finding out what Exim processes are doing

exiwhat

On operating systems that can restart a system call after receiving a signal (most modern OS), an

Exim process responds to the SIGUSR1 signal by writing a line describing what it is doing to the file exim-process.info in the Exim spool directory. The

exiwhat script sends the signal to all

Exim processes it can find, having first emptied the file. It then waits for one second to allow the

Exim processes to react before displaying the results. In order to run

exiwhat successfully you have to have sufficient privilege to send the signal to the

Exim processes, so it is normally run as root. Unfortunately, the

ps command which

exiwhat uses to find

Exim processes varies in different operating systems. Not only are different options used, but the format of the output is different. For this reason, there are some system configuration options that configure exactly how

exiwhat works. If it doesn't seem to be working for you, check the following compile-time options:

• EXIWHAT_PS_CMD
      the command for running « ps »
• EXIWHAT_PS_ARG
      the argument for « ps »
• EXIWHAT_EGREP_ARG
      the argument for « egrep » to select from « ps » output
• EXIWHAT_KILL_ARG
      the argument for the « kill » command

An example of typical output from

exiwhat is

 164 daemon: -q1h, listening on port 25
10483 running queue: waiting for 0tAycK-0002ij-00 (10492)
10492 delivering 0tAycK-0002ij-00 to mail.ref.example [10.19.42.42]
  (editor@ref.example)
10592 handling incoming call from [192.168.243.242]
10628 accepting a local non-SMTP message

The first number in the output line is the process number. The third line has been split here, in order to fit it on the page.

This manual page needs a major re-work. If somebody knows better groff than us and has more experience in writing manual pages, any patches would be greatly appreciated.
