hi 123ralle
May by this looks a bit strange..
but this is the file.


The file is emty

is this good or bad?

around 03:00PM i gave it 777 permissions to see if that was the problem.

Palermo,

please check with
ps -ef | grep ndo2db
if you have an running daemon, if not please start the ndo2db
daemon via
/usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg

and tell us the output

[Palermo]

Hi

Well this is the output of the commando you gave me

Code: Select all

[root@localhost ~]# ps -ef | grep ndo2db 
nagios    5825     1  0 Sep22 ?        00:00:00 /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg
nagios   13137     1  0 Sep22 ?        00:00:00 /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg
nagios   13279     1  0 Sep23 ?        00:00:00 /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg
root     20412 20342  0 19:53 pts/1    00:00:00 grep ndo2db
[root@localhost ~]# 

And this is what i get if i try to start the deamon.

Code: Select all

[root@localhost ~]# /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg 
Could not bind socket: Address already in use
[root@localhost ~]#

thx in advanced for your help...

[Palermo]

Could it be that nagios cannot connect to the database be course in the file: ndodb.cfg is have this rule:

Code: Select all

socket_type=tcp

and in the file: ndomod.cgf

Code: Select all

output_type=tcpsocket

And in th database :

Code: Select all

Should the database also need to work on TCP connection.
Could this be the problem? instead of the UNIX socket?

I have successfully install the NPC Plugin into Cacti; however, I cannot get the HOSTS, SERVICES, ETC. to populate. I have tried different things but I cannot get the broker_module to load. I get the following error message:

[1222374752] Local time is Thu Sep 25 16:32:32 EDT 2008
[1222374752] LOG VERSION: 2.0
[1222374752] Error: Could not safely copy module 'broker_module=/usr/local/nagios/bin/ndomod.o'.
The module will not be loaded: No such file or directory
[1222374752] Finished daemonizing... (New PID=12078)

I have Nagios 3.0.3 installed on a CentOS 5.2 box using PHP 5.2.6 and Apache 2.2.3

Thanks for the help

[Palermo]

Well.
I could not find the solution for this problem.
I stared all over from scratch.
After installing cacti and nagios and ndoutils it works.
So the installing went somehow wrong.

The only thing i have troubles with is installing the PHP-JSON packet.

edit: for the php-json problem if found great solution herehttp://forums.crm.saeven.net/showthread.php?t=128

Hi there,

I installed the NPC plugin (last version found http://trac2.assembla.com/npc 2.0.0b).

Nagios3 is also installed with ndoutils (using debian backports for etch).

My cacti database is loaded with the npc_* tables and they also have datas in them.

The problem is that I get nothing (ie : no data displayed) on the dashboard.

Can anyone help me deal with this issue ? Where should I start ?

Thanks.

Hi i'm gona try to help ok.
I'm quite new myself so... i just got it working now..
i asume that the necessary plugins are install t like php-json and php-pdo.

if you manual enter a switch in de nagios configuration (switch.cfg(/usr/local/nagios/etc/objects)).
do you see the switch or system being monitor t

Thanks !

json and pdo are already installed under debian with the following packages :
libapache2-mod-php5 and php5-mysql.

if you manual enter a switch in de nagios configuration (switch.cfg(/usr/local/nagios/etc/objects)).
do you see the switch or system being monitor t

In fact, the tables are loaded with items ready to be displayed But I will test it tomorrow.

Thanks for your help.

Right now I am doing a proof of concept using npc, nsca and ndoutils. Basically seeing if we can do all we want to do without spending tons of money on another product that does the same thing.
Everything is working great so far except for one thing:
I cannot create any data input methods to graph for any services that are being checked passively. I can create data input methods fine for servcies that are being checked actively. Is there something obvious I missed?

Thank you.

you are missing mysql support in PDO.

Quite sure you need to edit the $config['url_path'] variable in:
include/global.php
so that it says:
$config['url_path'] = '/cacti/';
