Error: Could not load module '/usr/local/nagios/bin/ndo2db'

[ridder75]

Hi,

I've got problem in nagios log :

Error: Could not load module '/usr/local/nagios/bin/ndo2db' -> file not found

How can i solve this problem please?

For information, i have this information in Configuration ==> Nagios ==> nagios.cfg :

/usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg

Thanks for your help.

Are you using ndoutils with your nagios installation? If so could you verify that ndo2db is actually located in /usr/local/nagios/bin/. If it is not try a:

Code: Select all

locate ndo2db

OK, let's try a couple things. First alter the line in your config

Code: Select all

/usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg

To:

Code: Select all

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

The stop nagios service, start ndo2db service, and restart nagios service again:

Code: Select all

service nagios stop; service ndo2db start; service nagios start

Let me know how that starts working for you. What is happening, or so it seems, is that you want to start nagios with the ndomod module so that it can correctly interface with ndo2db, then the ndo2db application is actually a daemon all on its own.

Hi,

Manipulations :

Multiple Broker Module
This directive can be used multiple times, see nagios documentation.
NDO use the broker module directive.

Configuration Nagios nagios.cfg :

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

[root@xxxxxxxxxxxxxxx ~]# service nagios stop; service ndo2db start; service nagios start
Stopping nagios (via systemctl): [ OK ]
Starting ndo2db (via systemctl): [ OK ]
Starting nagios (via systemctl): [ OK ]


I've got the same error :

Just to rule this out a type, do you have the "broker_module" directive before your ndo path?

Code: Select all

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

[ridder75]

Hi,

I typed exactly this in Centreon 2.3.9 :

Configuration ==> Nagios ==> nagios.cfg ==> Data :

Section broker module :

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

And i made :

Configuration ==> Nagios ==> Actions :

Generate Configuration Files Include Comments
Run Nagios debug (-v)
Move Export Files
Restart Nagios
Export

Result ==> http://xxx.xxx.xxx.xxx/nagios/cgi-bin/showlog.cgi :

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

I don't understand what did it happen

Let's check the permissions for directories above where ndomod.o is. Please run the following commands and send us output. At this point it might seem that permissions are limited somewhere in parent folder.

Code: Select all

ls -lv /usr | grep local
ls -lv /usr/local | grep nagios
ls -lv /usr/local/nagios

[ridder75]

Hi,

OK, looks like permissions are fine. Something I found for someone else last week or so, is that we don't actually want to be calling ndo2db from nagios.cfg as if it were calling an executable, but instead need to inform nagios to load it as a module. Try adding the following line to your config in place of the ndo2db -c .../ndo2db.cfg line:

Code: Select all

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

Then run the commands to stop and start both processes:

Code: Select all

service nagios stop
service ndo2db restart
service nagios start
