These log should be owned by nagios.
Code: Select all
chown nagios:nagios /usr/local/nagios/var/archives/*

OK, i have changed the owner, there is no impact with my archive log. the file log on archive folder didn't created for today archive log.
and my nagios.log file size always increase , because daily log rotation not working properly. any idea ??

Lets check the config for log rotation:
Code: Select all
grep log /usr/local/nagios/etc/nagios.cfg

Log rotation method is daily (d) as below :
# grep log /usr/local/nagios/etc/nagios.cfg
log_event_handlers=0
log_archive_path=/usr/local/nagios/var/archives
log_external_commands=0
log_file=/usr/local/nagios/var/nagios.log
log_host_retries=1
log_initial_states=0
log_notifications=1
log_passive_checks=0
log_rotation_method=d
log_service_retries=1
use_syslog=1

Is syslog running?
You may want to restart it anyways:
Code: Select all
service rsyslog stop
killall rsyslog
service rsyslog start

Did you restart rsyslog for good measure? So your logs have not rotated since the 17th?
