Nagios Support Forum

Hi,

I made changes in /usr/local/nagios/etc/nagios.cfg :

...
broker_module=/usr/local/nagios/bin/ndomod.o config_file=/usr/local/nagios/etc/ndomod.cfg
...

[root@xxxxxxxxxxx /]# service nagios stop
Stopping nagios (via systemctl): [ OK ]
[root@xxxxxxxxxxx /]# service ndo2db restart
Restarting ndo2db (via systemctl): [ OK ]
[root@xxxxxxxxxxx /]# service nagios start
Starting nagios (via systemctl): [ OK ]

Check File: /usr/local/nagios/var/nagios.log :

How can i solve it please?

Thanks.

That generally happens when you're trying to log to the database and it cannot connect to the database. Can you make sure the credentials you are supplying in the etc/ndo2db.cfg are valid. They are given under the directives db_host, db_port, db_name, db_user, db_pass, db_prefix. Can you connect to the database its attempting to connect to manually?

Hi,

The problem is solve, i followed this tuto :

http://sysengineers.wordpress.com/2010/ ... rh-el-oel/

ndo2db must be started before nagios, then after a chkconfig :

nagios 0:arrêt 1:arrêt 2:marche 3:marche 4:marche 5:marche 6:arrêt
ndo2db 0:arrêt 1:arrêt 2:arrêt 3:arrêt 4:arrêt 5:arrêt 6:arrêt
ndodaemon 0:arrêt 1:arrêt 2:marche 3:marche 4:marche 5:marche 6:arrêt
