Hi everyone,

I try to implement the nagios mobile in a groundwork/nagios solution. I can access the webpage succesfully but no host/service informtion are shown. In the php log I can examine such messages:

[04-May-2012 11:32:26] PHP Warning: Variable passed to each() is not an array or object in /usr/local/groundwork/nagiosmobile/includes/functions.inc.php on line 187

My include.inc.php looks like:
$STATUS_FILE = "/usr/local/groundwork/nagios/var/status.dat";
$COMMAND_FILE = "/usr/local/groundwork/nagios/var/spool/nagios.cmd";
$CGI_FILE = "/usr/local/groundwork/nagios/etc/cgi.cfg";
$OBJECTS_FILE = "/usr/local/groundwork/nagios/var/objects.cache";
$BASE_URL = '/mobile';
$TTL = 30; //Time to live for cached data parsed from status and objects file
$USER = ''; //you can hard-code the 'nagiosadmin' if you don't want any authentication: NOT RECOMMENDED!!

My someone can help me.

With best regards from germany...

From looking at the error messages, it seems like Nagios Mobile wasn't able to read any of the status data. Maybe a permissions issue?

Also, we haven't tested in a groundwork environment, and I don't know if they've changed any formatting in either the status.dat or objects.cache file, but if they have it would definitely throw off the data parser.

The format of the status.dat and objects.cache files are the same like the one in a normal nagios installation. I have compared the files. The groundwork nagios instance such a normal standard installation of nagios.
Permissions are correct, too:
-rw-r--r--. 1 nagios nagios 65089 7. Mai 10:41 objects.cache
-rw-rw-r--. 1 nagios nagios 45477 7. Mai 11:46 status.dat

The httpd deamon in running with 'nagios' user privileges.
Could it be some php restrictions? Running php version is 5.2.6. I have attached the php.ini.

Maybe some can give me a tip.

Thanks and best regards

Hmm, try changing the ownership of the Nagios Mobile scripts to nagios.nagios. Also,if you've got SELinux enabled, try disabling it and see if that makes a difference.

Hello All,

I also have the same issue, i'm not able to see any information. I have nagios nagios for permissions set on the directories. Please see sreenshot attached.

Thank you for your time!

Thanks,
Nando

Can you verify the directory locations of the following files?

objects.cache
status.dat
cgi.cfg

and verify that these math the locations in the include.inc.php file:

Code: Select all

$STATUS_FILE  = "/usr/local/nagios/var/status.dat";
$COMMAND_FILE = "/usr/local/nagios/var/rw/nagios.cmd";
$CGI_FILE = "/usr/local/nagios/etc/cgi.cfg";
$OBJECTS_FILE = "/usr/local/nagios/var/objects.cache";
$BASE_URL = '/nagiosmobile';

[mendonca]

Here's what i have for include.inc.php. I've verifed that these file locations are correct. I'm running an older version of Nagios (Nagios 2.11) would that make a
difference? Also, i've verified that SELinux is disabled.

$STATUS_FILE = "/var/log/nagios/status.dat";
$COMMAND_FILE = "/var/log/nagios/rw/nagios.cmd";
$CGI_FILE = "/etc/nagios/cgi.cfg";
$OBJECTS_FILE = "/var/log/nagios/objects.cache";
$BASE_URL = '/nagiosmobile';
$TTL = 30; //Time to live for cached data parsed from status and objects file
$USER = ''; //you can hard-code the 'nagiosadmin' if you don't want any authentication: NOT RECOMMENDED!!

Is apache part of your nagios group?

Code: Select all

cat /etc/group|grep nagios

[mendonca]

Yes, Apache is apart of the Nagios group.

Thanks!

I'm running an older version of Nagios (Nagios 2.11) would that make a
difference?

I just caught this now. Nagios Mobile has never been tested against a Nagios 2.x install. I'm pretty sure the status and object data formats changed from Nagios 2-3, so that's likely the cause.
