Command Monitor is a tool that allows you to periodically execute a command and watch the results of it. For instance, if you want to scan for wireless networks using "iwlist eth1 scan" you have to repeat that command each time you want to see if there's a new one. This program does it for you.
Command Monitor also allows you to execute the commands in a remote host using an SSH connection. Now you can comfortably watch the number of Apache child processes of your server.
Read the INSTALL file in the package for installation instructions.
Requires libssh from Aris Adamantiadis for the SSH functionality.
