Umm, no. If that was nagios then the above would also be nagios. This is 
the 'default' plugin output for networking plugins that time out. 
check_nrpe does it a bit differently so as to distinguish between the 
check_nrpe plugin timing out and the remote plugin it's executing doing 
the same.

Ignore that, and check for the -t option in your checkcommands file.

That depends on max_check_attempts, but host checks are done in a 
serialized manner, so a temporary spike lasting longer than 
max_check_attempts * plugin timeout will render a critical.
