Nagios Error: Could not read object configuration [SOLVED]

Hi!

Today i merged nagios for the first time.
when i browse to http://localhost/nagios and klick one item beneath "Monitoring" i got the following:

Whoops!

Error: Could not read object configuration data!

Here are some things you should check in order to resolve this error:

1. Verify configuration options using the -v command-line option to check for errors.
2. Check the Nagios log file for messages relating to startup or status data errors.
3. Make sure you've compiled the main program and the CGIs to use the same object data storage options (i.e. default text file or template-based file).

i checkt the first thing. there where some problems but i solved them.
the log-file should be placed in /var/nagios/nagios.log but there is none. and i couldn't find it anywhere else.

i played with the permissions. i studied the documentation if gentoo forgot something and of corse i searched with google and in other forums.
but i couldn"t find anything usefull.

can anybody help

Check the access rights to /etc/nagios.

I seem to remember them being incorrect for apache to have read access to this folder.

i've checked de permissions of /etc/nagios.
apache can access it. (drwxr-x--- nagios apache /etc/nagios)
i also added the apache-user to the group nagios.

i created the pipe "prw-rw---- nagios apache /var/nagios/rw/nagios.cmd"

sorry. nothing happend.
no logfiles, same error in the browser.

any other ideas?

ps: it is nagios 2.4

Have you added -D NAGIOS to /etc/conf.d/apache2?

I'm just doing a fresh install with the following to see if I can re-create your troubles:

-D NAGIOS is added to /etc/conf.d/apache2
apache was restartet 10000 times i think

"emerge -pv nagios-core nagios-imagepack nagios-plugins nagios-nsca nagios-nrpe nagios" gives me the following:

[ebuild R ] net-analyzer/nagios-core-2.4 USE="apache2 perl -debug -noweb" 0 kB
[ebuild R ] net-analyzer/nagios-imagepack-1.0-r1 0 kB
[ebuild R ] net-analyzer/nagios-plugins-1.4.3 USE="ipv6 ldap mysql nagios-dns nagios-ntp nagios-ping nagios-ssh postgres radius samba snmp ssl ups -nag
ios-game" 0 kB
[ebuild R ] net-analyzer/nagios-nsca-2.6 0 kB
[ebuild R ] net-analyzer/nagios-nrpe-2.5.1 USE="ssl -command-args" 0 kB
[ebuild UD] net-analyzer/nagios-imagepack-1.0 [1.0-r1] 0 kB
[ebuild R ] net-analyzer/nagios-2.4 0 kB

i think i will try to remove some use-flags in /etc/portage/package.use

Does your nagios process actually start when you run '/etc/init.d/nagios start'.... does it appear in your process list.

it works!

it was a very strange problem.
i wondered why i didn't have the file /etc/init.d/nagios but it was the first time it tried nagios. so i didn't know it better.
after you wrote me that it should be there i remerged the nagios packages and there it is.
now i only had to to do a "/etc/init.d/nagios start" and that's it.

thank you very much
