Hi
i'm trying to install ndoutils with ndo2db on a Freebsd host.

the nagios.cfg files have this option

temp_path=/tmp
event_broker_options=-1
broker_module=/usr/local/bin/ndomod.o config_file=/usr/local/etc/nagios/ndomod.cfg

debug_level=-1
debug_verbosity=2

if a list the file i see

Code: Select all

root@margherasv1:/usr/local/libexec # ls -l /usr/local/bin/ndo*
-r-xr-xr-x  1 root    wheel   105560 Oct 12 15:18 /usr/local/bin/ndo2db
lrwxr-xr-x  1 root    wheel       21 Oct 11 13:30 /usr/local/bin/ndo2db-3x -> /usr/local/bin/ndo2db
-r-xr-xr-x  1 nagios  nagios   72772 Oct 12 15:18 /usr/local/bin/ndomod.o

-rw-r--r--  1 nagios  nagios  6 Oct 18 12:15 ndo2db.pid

How can i debug the nagios's broker module to understand what happen?

Thanks Alex

The ndo configuration file may be bad. Can you post a copy of /usr/local/etc/nagios/ndomod.cfg ?

Also check the module with "file /usr/local/bin/ndomod.o"

Enabling the debug option in nagios.cfg and trying to restart it may also give some useful information. Edit nagios.cfg and find the lines:

debug_file=/usr/local/nagios/var/nagios.debug
debug_level=0

Changing the debug level to -1 to enable debugging.

Ok i have uploaded the nagios.cfg file
Before i installed the old version 3.5, now i'm using the same cfg file.

this is the exit of file command

Code: Select all

root@margherasv1:/usr/local/etc/nagios # file /usr/local/bin/ndomod.o
/usr/local/bin/ndomod.o: ELF 32-bit LSB shared object, Intel 80386, version 1 (FreeBSD), dynamically linked, stripped
root@margherasv1:/usr/local/etc/nagios #

nagios.cfg is already setting with dbug level to -1

this is output of nagios.log.

What version of ndoutils ? Did you receive any errors while compiling and install it?

Try running an stracewhen starting the nagios process:

strace /usr/local/nagios/bin/nagios /usr/local/nagios/etc/nagios.cfg

The version is ndoutils-2.1.3 and i have installed by ports collection command.
in

Code: Select all

 /usr/ports/net-mgmt/ndoutils/make install

without problem
I have modified the directory where ndo2db write pid,log and debug files; in origin was /var/run now is /var/run/ndo2db so i can use nagios as user to run process.

The version is

root@margherasv1:/usr/home/martin # ndo2db -V
NDO2DB 2.1.3

Was Nagios installed via ndoutils as well?

We have instructions for installing Nagios via source at https://support.nagios.com/kb/article/n ... ml#FreeBSD as well as ndoutils at https://support.nagios.com/kb/article.p ... 06#FreeBSD. We don't have any control over the packages and installing from source may be your better bet.

Hi after some day, following your instruction, i was successful to install nagios and ndoutils from source.
Now it work fine and pull the data in mysql DB
Probably the packages in Freebsd is not well configured
Thanks
Best regards.
