External commands and nagios.log

[Keller, Mark D]

Ah, thank you for that point. I guess I was misinterpreting the meaning of those options.

I did what you said and now the logs are looking to be way smaller. I also trimmed out the passive and external command check lines from my previous logs. The history reporting is working way faster now and is actually usable.

Thanks for the help!

Mark

These are the previously mentions passive service checks, not external  
commands. Logging treats them differently even though the mechanism to  
get both to nagios is the same.

This is the one you want set to 0. Make sure that nagios is restarted  
and that you only have one nagios daemon running. These are the  
settings I use --

log_file=/usr/local/nagios/var/nagios.log
log_rotation_method=d
log_archive_path=/usr/local/nagios/var/archives
log_notifications=1
log_service_retries=1
log_host_retries=1
log_event_handlers=1
log_initial_states=0
log_external_commands=1
log_passive_checks=0
