Ubuntu has evolved over the last years, and has become quite popular on the desktop. Ubuntu is also working on its position in the enterprise.

send pages / email to defined list
Tracks systems that are already down so as not to resend email / pages

Now with more that 1 year in production, performance is great (as shown below), and the filesystem is stable. No issues. Onto the details… (more…)
