Re: Monitoring Desktops

[Lutz Mader]

Hello Graham,
as long as the desktop systems are Linux systems, the simple answer here
is M/Monit to monitor all systems centrally.

On the other hand, I use a similar approach to yours to monitor
applications on other systems (I check the availability of a port) to
start central applications. But I need an alert after 20 minutes, or
wait only 50 minutes for the other systems.

Nice to see that you have enough systems to go several days without one.

Sorry, I use a similar approach,
Lutz
