Hello @ivp2015,

After making changes, did you successfully Apply Configuration? If there's an error in the configs, it would revert back to the last known good configuration.

Otherwise, you may have more than one Nagios process running and please run through the commands to completely re-start Nagios XI.

Code: Select all

systemctl stop crond
systemctl stop npcd
systemctl stop nagios
systemctl stop ndo2db
pkill -9 -u nagios
for i in $(ipcs -q | grep nagios |awk '{print $2}'); do ipcrm -q $i; done
rm -rf /usr/local/nagiosxi/var/dbmaint.lock
rm -rf /usr/local/nagiosxi/var/event_handler.lock
rm -rf /usr/local/nagiosxi/scripts/reconfigure_nagios.lock
systemctl restart mariadb
systemctl start ndo2db
systemctl start nagios
systemctl start npcd
systemctl start crond

No, but a simplified version would be to just stop and re-start the nagios service.

Code: Select all

systemctl stop nagios.service
killall nagios
systemctl start nagios.service
