Nagios Support Forum

Hi All,

Is it possible if I can configure my new services from Nagios Core Web UI.? Currently, I am using nagios core 4.3.4 version.

Please let me know If I can do that from Web UI also.

No, Core does not have a web interface for configuration. Our commercial product Nagios XI can do that, otherwise there is a third-party addon called NagiosQL that is meant to work with Core, but we do not provide support for that.

Here's a post I made on the topic:
https://support.nagios.com/forum/viewto ... 57#p250757

If you're into configuration management, I've found the nagios cookbook on the Chef supermarket to be a delight to work with. Though that's not really a simple "Web UI".

Thanks for the assist, @mcapra!

@Ravikimt, please let us know if you need further assistance.

Thanks team for your assistance, I will try NagiosQL and let you know if I face any difficulty.

We'll keep this open for you.

I have downloaded NagiosQL on my system(Ubuntu 16.04 LTS) but when I am trying to open the NagiosQL application via this url http://localhost/nagiosql32/install/index.php, It gives me below mentioned error:-

**********************************************************************
The requested URL /nagiosql32/nagios/install/index.php was not found on this server.

Apache/2.4.18 (Ubuntu) Server at localhost Port 80
***********************************************************************

But I have verified this directory/files "nagiosql32/install/index.php" are available on my local system. Can you please assist me on this.?

It seems your nagiosql directory is not reachable for your webserver.

Have you configured your apache2 server? What is the DocumentRoot of your server? By default Ubuntu 16.04 has /var/www/html as DocumentRoot, so your nagiosql directory should be located below this path, as example in /var/www/html/nagiosql/install/index.php.

Your path is named nagiosql32 - have you downloaded NagioQL 3.2.0 or the new 3.4.0 version? Ubuntu 16.04 comes with PHP7 - therefore you should use NagiosQL 3.4.0 - version 3.2.0 is for PHP5 only.

I have followed below mentioned steps for NagiosQL installation. Please have a look at this and let me know.
What was went wrong.?

1-Download nagiosql_320.tar.gz
2-cp nagiosql_320.tar.gz /var/www
3-sudo chown -R www-data:www-data nagiosql32
4-sudo vim /etc/apache2/sites-available/nagiosql32.conf
5-add the following lines

Alias /nagiosql32 /var/www/nagiosql32/

<Directory /var/www/nagiosql32/>
Options None
Order allow,deny
allow from all
</Directory>
Save and exit the file

6-Enable NagioSQL website using the following command
sudo a2ensite nagiosql32

7-To activate the new configuration, you need to run:
sudo service apache2 reload

8-Now you can access the NgiosQL web interface using the following URL
http://serverip/nagiosql32

I hope it will help us to debug the issue and now I am facing one more problem after performing these steps I am not able to start/restart my apache service also. getting this error.

I don't know much about NagiosQL, but the error is in your apache configuration as systemctl mentions:
