Nagios Support Forum

Hi All...

I know installing Nagios xi on Debian is not officially supported, but I've decided to have a go.

I have managed to install what I think are all of the required patches and execute the install scripts with a couple of modifications (apache user and a couple of paths in the init.sh file). What I currently have is an installation that I can login to and navigate through. If I want to make any changes to anything eg add a host or service, I work my way through the wizard and begin to get "Invalid Argument supplied" errors relating to the use of foreach() in a number of php files.

After a quick look, it appears that the php file is expecting data in the form of an array and it is not getting an array.

Some examples are:

On the Service Status page - Warning: Invalid argument supplied for foreach() in /usr/local/nagiosxi/html/includes/components/xicore/ajaxhelpers-servicestatus.inc.php on line 361
Step 5 of the Generic Network Device Monitoring Wizard in the Other Individual Contacts box - Warning: Invalid argument supplied for foreach() in /usr/local/nagiosxi/html/config/monitoringwizard.php on line 859
Step 5 of the Generic Network Device Monitoring Wizard in the Specific contact groups box - Warning: Invalid argument supplied for foreach() in /usr/local/nagiosxi/html/config/monitoringwizard.php on line 882
Step 6 of the Generic Network Device Monitoring Wizard in the Host Groups box - Warning: Invalid argument supplied for foreach() in /usr/local/nagiosxi/html/config/monitoringwizard.php on line 1182
Step 6 of the Generic Network Device Monitoring Wizard in the Service Groups box - Warning: Invalid argument supplied for foreach() in /usr/local/nagiosxi/html/config/monitoringwizard.php on line 1207
Step 6 of the Generic Network Device Monitoring Wizard in the Parent Host box - Warning: Invalid argument supplied for foreach() in /usr/local/nagiosxi/html/config/monitoringwizard.php on line 1233
Applying the new service - Warning: Invalid argument supplied for foreach() in /usr/local/nagiosxi/html/includes/configwizards/genericnetdevice/genericnetdevice.inc.php on line 243

I would greatly appreciate any assistance with overcoming these errors. I suspect it will be something simple for someone who knows the back end code.

What version of PHP are you running?

The key items what would likely break on a Debian install are the postgresql and mysql setup for the Core Config Manager. Are you able to access and use the Core Config Manager in xi? If not, you'll have to really pick apart the install scripts to get things working and setup.

There's a LOT of places for an xi install to break in a Debian install. It will be hard to nail down where all the problems are without knowing more details in the install steps, and what succeeded, etc. The more details you can give on that, the better we might be able to point you in the right direction.

Lenny or Squeeze? I would think Lenny's PHP would be compatible at least, but Squeeze has a version that finally dropped a number of long-deprecated behaviors, breaking all sorts of stuff targeting "legacy" PHP installs like what Red Hat has.

Hi Guys...

Firstly, thanks very much for your replys.

I can confirm that I can login to the Nagiox xi Core Config Portal. I am able to click the config options in the menu down the left hand side and there don't appear to be any php errors when viewing any of the data. I am able to see one of the hosts I tried to create a service on previously, but no services defined.

I have edited a few files along the installation process, mainly to adjust install paths and usernames. I can provide copies of the files if required. Here is a breakdown of the installation steps performed:

I tried to muscle my way through the install scripts on Ubuntu about 2 months ago, the place I got hung up was on the setup and importing of the DB config for postgres. The configs for postgres are in different locations on Debian based machines, and you'll probably have to pick apart that part of the setup script to get those pieces installed correctly.

What were your results upon accessing the main xi page?

Hi There...

Thanks for the pointers. I'm not much of a PostgreSQL expert to say the least (guess I'm about to get better at it then)...

Opening up the main Nagios xi front page produces only 2 php errors, everything else appears and works fine (as far as I can tell):

Warning: fileowner() [function.fileowner]: stat failed for reset_config_perms in /usr/local/nagiosxi/nagiosql.inc.php on line 91
Warning: fileowner() [function.filewoner]: stat failed for reset_config_perms.sh in /usr/local/nagiosxi/html/includes/components/nagiosql/nagiosql.inc.php on line 91

Both of the php files are encrypted. The reset_config_perms and reset_config_perms.sh files have the following attributes:
-rwsr-xr-x 1 root nagios 6763 2011-01-02 01:12 /usr/local/nagiosxi/scripts/reset_config_perms
-rwxr-xr-x 1 nagios nagios 280 2011-01-02 01:12 /usr/local/nagiosxi/scripts/reset_config_perms.c
-rwsr-xr-x 1 root nagios 487 2011-01-02 01:12 /usr/local/nagiosxi/scripts/reset_config_perms.sh

Thanks again.

Andrew

Oh, hehe, those php errors are actually bugs in that php function, and that error message should disappear in our next update. If those are your only errors, then so far so good. So is the interface up and running then?

Hi There...

Yes, the interface appears to be fine. The only real issues I currently have is when I want to add some services to monitor via the wizard, I get php errors relating to the services array. eg

Step 5 of the Generic Network Device Monitoring Wizard in the Other Individual Contacts box - Warning: Invalid argument supplied for foreach() in /usr/local/nagiosxi/html/config/monitoringwizard.php on line 859

Standard php errors suggest that these errors mean that the input is not of the type array.

Andrew

That function calls an XML object. I'd check to make sure you've got all of the XML packages for PHP installed.

Hi There...

I'm pretty sure I have all of the required XML packages installed. I thought I'd have a look through the apache logs in the meantime. Found the monitoringwizard.php file is trying to call a jquery file that doesn't exist:
