Alert Manager allows you to monitor the output (exit status or text)
of any system command and take action when a command fails or
succeeds. It was created to handle all alert commands (emailing,
paging, etc.) for a production environment in which it is not
permissible to lose a single message. It has a very flexible
configuration file that allows the creation of "alert chains", chains
of alerts, each with its own alert command, fallback command, success
command, and other options. It has a method for passing messages
(alert text) from the commandline to the various alert commands
defined in the configuration file.
