Test Please: Buffer Slots Variable CVS Code

I think your monitoring server if completely overloaded (or am I looking at
the wrong stats?).

Here's one of my servers:

647 services:
Check Latency: (Min. Max. Average): 0.00 sec	8.56 sec	1.147 sec
load average: 0.62, 0.68, 0.64

How can you have 200 seconds service latency? This means that nagios is 200
seconds late in running scheduled active checks.
