loggle - syslog watcher/alerter
This is a little C++ program that combines the functionality of tail -F and
grep with a buffer and email.
I wrote this so I could get email alerts when my server got too hot.
I was already running lm-sensors and sensord, but they don't send email.
This code is designed to be lightweight and efficient.
It doesn't use the shell and doesn't spawn processes unless it's sending mail.
The code is loggle.cpp
and here is a Makefile.
There's also a Debian-style init script
and a defaults file.
