LogDog 2.00-RC5

LogDog is a tool that monitors messages passing through syslogd and takes action based on key words and phrases.
LogDog has a configuration file which allows you to specify a list of key words or phrases to alert on, and a list of commands that can be run when those words are encountered.
Main features:
- Monitors syslogd messages for key words and phrases and runs system commands based on content.
- Logs all activity to a file.
- HUP signal is intercepted correctly and causes Logdog to reload its configuration and refresh all filehandles.
- Reads data from syslogd via a FIFO for efficiency and low latency alerts.
- Script returns error status to the system when an error occurs.
- Verbose and descriptive error messages if something goes wrong.
- Multiple debugging levels.
Installation:
make install
Enhancements:
- Updated the pringmsg() function. It now logs and syslogs messages in a more syslog-like format.
- Made it so it doesnt drop permissions until after it opens/writes its PID file. This means that if you *are* dropping permissions a HUP signal will likely cause logdog to exit abruptly if your PID file is not writable by Logdog.
