[HowTo] Setup Nagios

[FeG]

Hi again...

... and that's the second HowTo:

HowTo - Setup Nagios.

It describes, how to setup the nagios webinterface under ispCP (that's causing some problems because it has to be run under /var/www.

The configuration of nagios is not covered by this HowTo; but it is covered very well by the default nagios setup and the nagios documentation

As with my other HowTo: Of course, there are mistakes in this HowTo - but I didn't found them already so if you do, please tell me...

Greetings

Not working in my ispcp this HowTo
my verios is -> ispCP Omega 1.0.0 RC2c

Hi,

I am running RC2c, too...

I think I've forgotten something, test this please:

In /etc/nagios2/cgi.cfg, change these values as shown below:

Code:

physical_html_path=/var/www/nagios/htdocs
url_html_path=/

Does this solve the problem?

If not, tell me what error you get..

Greetings
FeG

Edit:
Changed this in the HowTo... hope, that's all I forgot.

Ok thanks
Now .. i need add entry nagios in my DNS(bind) ?

ex:

nagios CNAME domain.com.br.

[keffer]

i have a new erro : )

In nagios, i get same error in all options, cgi configured (www-data/www-data), all inside cgi-bin with permissions

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).

Hi keffer,

as you've already quoted:

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).

It would be helpful, if you try out these suggestions:

1. Have a look at the configuration files...

Code:

nagios2 -v /etc/nagios2/nagios.cfg

2. Try to open nagios so that the error appears and then look into:

Code:

tail /var/log/nagios2/nagios.log

3. Is the nagios daemon running?

Code:

ps axxfu | grep nagios

If you don't find a solution this way, post the tail of nagios.log here...

Greetings,

Hi,

...

Have you opened the nagios-site after copying this logfile? Because normally, nagios should say something about that.. well, should

... but at the moment I've no idea what this could be :/
