Overview

These templates use ss_get_by_ssh.php to connect to a server via SSH and extract statistics from the Nginx server running there, by executing the "wget" program with the url "/server-status". This means you don't need to install any special tools. Standard Unix command-line tools are all you need.

Installation

Once the SSH setup is working, configure Nginx to report its status. You can add the following to any server context and restart Nginx:

location /server-status {
   stub_status on;
   allow 127.0.0.1
   # deny all;
}

If you decide to use a different URL, you'll have to configure that in the script configuration (covered in the general install guide) or pass a command-line option (also covered in the general install guide).

Finally, test one of your hosts like this. You may need to change some of the example values below, such as the cacti username and the hostname you're connecting to.

# su - cacti -c 'env -i php /var/www/cacti/scripts/ss_get_by_ssh.php --type nginx --host 127.0.0.1 --items az,b0'
