How to monitor an application using Nagios core

Question

I have containerized a web application on my localhost which is running at some port address. I want to monitor my website using Nagios core since it is a monitoring tool. Is there any way through which I can monitor my web app.

Does Nagios provide any feature or plugin through which it can be achieved?

Can anyone resolve my query?

Thanks.

Answer 1

Here is what you can try. Since Nagios has tcp and http plugins which you can use to monitor your web application.

The command which you can use to monitor the port is :

/usr/local/nagios/libexec/check_http -I ip_address_of_localhost -p port_address -u url_of_webapp

This will help you to check your web application. 

I hope the above information will be helpful to you.
