Hi,

In my case it shows NPC tab and data but Nagios status is "off"

Code: Select all

OS: CentOS release 5.6 x86_64
Cacti: 0.8.7g
RRD: 1.4.4
Apache: httpd-2.2.3-45

It is throwing following errors in cacti.logs:

I see that problem, but it was solved in 2 ways:

1.- Change the permissions of the nagios.cmd for rw-rw----- for the instance nagios:www-data,
then restart the service of nagios.

2.-Restart cacti.

The first step is located in the documentation of the package or google it with "nagios.cmd permissions"

Good Luck !!

Thanks a lot for replying, it is already set as:

Code: Select all

prw-rw---- 1 nagios nagcmd 0 Jun  2 09:32 nagios.cmd

[fg1010]

you need to put as nagios:www-data

To do this u need to type in the directory containing the nagios.cmd
chown nagios:www-data nagios.cmd

Also I suggest u to read about the ndoutils, because it's essential for the integration nagios cacti.

And if u install it don-t compile it, most of the time doesn-t work well, try

yum -y install ndoutils-nagios-mysql or a combination and then u can follow the manuals for integrations.

Hope u can resolve the problem and if u have more questions post it buddy

[shahsaifi]

Thanks mate, but I am still struggling with same issue
it is:

Code: Select all

# getent group nagcmd
nagcmd:x:501:nagios,apache,cacti

Plugin permissions are:

Code: Select all

# ls -ld /var/www/html/plugins/npc
drwxr-xr-x 10 apache nagcmd 4096 Jun  2 09:37 /var/www/html/plugins/npc

Is that still permission issue?

[fg1010]

What i know is that u need to grant permissions of execute in the folder plugin:

try:

chmod -R 777 /var/www/html/plugins

Its useful that the plugins folder have this permission, then restart apache.

and dont forget to configure the ndoutils with the integration of nagios.

Why don't try to post the nagios.cfg and the ndomod.cfg and the ndo2db.cfg ???

Good luck

[shahsaifi]

Dear Friend,

Please refer attached configs.

[fg1010]

I've checked the files and have a question:

apache and the user u have are members of the group nagios ???

The rest of the config was clean i must say, but considering that i have the same problem ( almost got crazy .... lol ) u need to one of the 2 choices:

1.- try to edit the ndoutils (try locate ndoutils ), u can find 2 forms of the ndoutils, one that have much lines and another file that have someting similiar to :

Code: Select all

srv-cacti@srv-cacti:~$ more /etc/default/ndoutils 
# Defaults for ndoutils-nagios3-mysql initscript
# sourced by /etc/init.d/ndoutils
# installed at /etc/default/ndoutils by the maintainer scripts

#
# This is a POSIX shell fragment
#

# You have to enable ndoutils broker module first to use ndoutils.
# (see /usr/share/doc/ndoutils-nagios3-mysql/README.Debian)
ENABLE_NDOUTILS=1

# Additional options that are passed to the Daemon.
DAEMON_OPTS="-c /etc/nagios3/ndo2db.cfg"

try to tune the DAEMON_OPTS to your ndo2db.cfg

2.- Try to find and install the package ndoutils-nagios3-mysql
and install it but don-t try to compile it in some cases compiling can become a problem.

If u find and install the package try to configure the ndomod.cfg and the ndo2db.cfg in the same way that
u have the config files and change the line (broker module) in the nagios.cfg.

You've saved a lot of work in this way.

Either choice u take if u have any problem feel free to post it !!

Hi,

Yes! apache and cacti both are the members of nagcmd which is a nagios group.

Code: Select all

# getent group nagcmd
nagcmd:x:501:nagios,apache,cacti

# ls  -ld /usr/local/nagios/
drwxrwxr-x 10 nagios nagcmd 4096 Jun  3 01:30 /usr/local/nagios/

# ls -ld /var/www/html/plugins
drwxrwxrwx 10 apache nagcmd 4096 Jun  3 05:50 /var/www/html/plugins

I guess, you are talking ndoutils on Ubuntu, i'm using centos and compiled ndoutils from source Please suggest

[fg1010]

Ok. I will make a cacti in centos 5.3 in one VM to experiment your problems and i will post it the results, in the meantime i would suggest you to try one of this solutions:

Try to download and install one of this packets of ndoutils according to ur version of centos:

http://pkgs.org/search/?keyword=ndoutil ... it&exact=0

OR

try to follow this guide:

http://kezhong.wordpress.com/2011/05/29 ... fedora-14/

I believe that will work for centOS too but i will confirm it when i do the trick of the VM.

Good luck buddy !
