Host/Service State Log Entries

[Thomas Stocking]

Scott,
Marc is right - this is neither a bug, nor a misconfiguration. It is 
purposeful behavior. It was added to Nagios by the developer as a fix 
for another issue with the reports. You can't control it without 
modification to the source code, unless both you and I and Marc are all 
missing something.
I also see these log entries at log rotation, regardless of my 
log_initial_states setting. If I enable this option I *also* see these 
at, or just after, restart, and it balloons my log files in large 
systems, hence I refrain from setting it. I tolerate the entries at log 
rotation, though I admit that it would be nice to be able to turn these 
off :)
