NagiosXI is not graphing

[fraguillen]

Good morning dear

We were presented with an event this morning where an Oracle VM was turned off and therefore turned off the virtual ones that will run on it, including our NagiosXI production server.

When really the server, we notice that it is not graphing.

What should we check to fix this problem?

Best regards...

You may have some files that need to be cleaned up since the shutdown likely wasn't neat. First I would run a database repair:

Code: Select all

/usr/local/nagiosxi/scripts/repair_databases.sh

And then assuming you're using CentOS/RHEL 7 with modgearman, run this:

Code: Select all

systemctl stop httpd
systemctl stop crond
systemctl stop npcd
systemctl stop nagios
systemctl stop ndo2db
systemctl stop mod-gearman-worker
systemctl stop gearmand
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 stop mysqld
systemctl start mysqld
systemctl start gearmand
systemctl start mod-gearman-worker
systemctl start ndo2db
systemctl start nagios
systemctl start npcd
systemctl start crond
systemctl start httpd

If you're using a version 6 Cent or Redhat, you'd want to use start and stop commands like "service mysqld stop" and "service mysqld start". If you're not using gearman then you can skip those commands or just ignore the messages you get when you run them.
