Is monitoring broken?

Whenever I reboot my server (a host32), I have major issues getting it to come back up. I usually keep monitoring disabled, since I do not want the tech's interfering with it for brief outages.

I've just rebooted it due to a stubborn directory that would not delete. I need to boot it into safe mode to remove the directory, before I can reinstall the program that uses it.

I'm currently looking at a blank KVM screen, since the server has powered off instead of rebooting. Whenever this happens, the 'set power on' and 'set reboot' buttons have no effect.

If I try and reboot it via the manager when it ends up in this state, I get an e-mail saying it has rebooted,and responds to ping, when it has not, and it cannot respond to ping.

This makes me wonder....what ARE ovh actually monitoring when they send these e-mails?

I know the server itself is unlikely to be faulty, since it's had nearly every component replaced over the several years that i've had it (memory, power supply, 2 motherboards, several harddrives).

This makes me think either ovh are lying when the reboot e-mails are sent, or the monitoring is broken.
