RE: [Nagios-db-devel] Error loading module

[Michael H. <mic...@ax...>]

I modified the makefile with the correct locations of the postgres =
libraries and Nagios headers for my system:
=20
all:
        gcc -Wall -g -O2 -o inserter.o inserter.c -shared =
-I/usr/local/src/nagios-2.0b3/include -I/usr/local/pgsql/include =
/usr/lib/libpq.a
=20
and did "make all". In hindsight the pgsql include directory did nothing =
as that directory doesn't exist but the postgres header is in =
/usr/include (rpm install of postgres) so it all worked out in the end. =
I copied the resulting inserter.o to my nagios installation.
=20
I am using the tarball from sourceforge; I'm not a developer and don't =
have CVS set up.
=20
Is there any chance that you could do a new release? Being able to =
configure the module would be a really nice feature to have...  :)
=20
Also if you could add a paragraph to README about how to add the NEB =
module to nagios (ie use a "broker_module" directive in nagios.cfg) this =
would be appreciated. As with all things it's obvious in hindsight but I =
did spend some time yesterday wondering WTF I was supposed to do with =
inserter.o.
=20
Thanks!

How did you compile the module? Somebody else had a similar issue, but
they had ommited some libraries.

If you pull from CVS, you can set the connection params in your nagios
config file. If you pull the most recent tarball (0.91 I believe) then =
you
have to modify inserter.c to change your connection settings.

You need to tweak the makefile provided with inserter.c to add the libs =
that contain BIO_new_mem_buf and some other functions. Those libs are =
commented out, below the active lines: "-lssl -lkrb5 -lcrypt". Of course =
you need the corresponding libs installed.
And yes the connection string is hardcoded, at the line 78. Just put =
your server and DB name here

I was eventually able to compile a module which loaded into Nagios and
initialised correctly, but it complained that it wasn't able to clear
the configuration. Try as I might, I just couldn't get it to work.

I downloaded and installed MySQL and tried the MySQL NEB module.
I had to add zlib to the list of libraries during compilation but after
that it worked with no problems.

Thanks to Ben and Thibault for your help, and to Matthew Kent for
writing
the MySQL module.

Sorry to hear you couldn't get the postgres one to work. You wouldn't by 
chance remember the error you were getting?

RE: [Nagios-db-devel] Error loading module

[Michael H. <mic...@ax...>]

Sorry Ben I no-longer have access to the system otherwise I'd include
the log here. I believe the first error was the module calling a stored
procedure to clear the configuration:

135	res =3D PQexec(pgconn,"select empty_config()");

which resulted in this message being printed:

138	snprintf(q,sizeof(q),"nagios-db: couldn't clear config info
(%s)", PQresultErrorMessage(res));

with an empty string from PQresultErrorMessage(). From there the log
just
filled with error messages until Nagios shut itself down.

Thanks,

	Michael

I do want to make a new release. However, I was hoping I could get  
some documentation into it...... unfortunately I've just been too  
busy to write it.
