While I agree this particular info is missing, the active check latency
tells you how much you're lagging behind. As long as it's near 0 you're
OK, but when it starts to show big latencies (i.e. >30 seconds) even
keeps growing then you definitely have a problem.
Also note that service latency is not always a "server performance
problem". In Nagios 2.0, host checks are run serially so the time in
takes to run host checks can cause latency to grow up pretty fast,
especially when you start seeing hosts down.
There's other reason for high latencies: perfdata commands, ocsd
commands, etc. Ideally you can avoid this by having Nagios write a file
or FIFO instead... There's many example out there.
