LibreNMS - snmp extend nginx

NginX LibreNMS script

Get the script:

wget https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/nginx -O /etc/snmp/nginx

Unzip and copy it where you need. Make it executable.

Adapt the url in the script to your configuration, eg:

data = urlopen('http://127.0.0.1/nginx_status').read()

Be careful, 'localhost' seems bugging, use 127.0.0.1 instead...

vHOST

Adapt your config with:

server {
                listen 127.0.0.1:80;
                server_name 127.0.0.1;

                location /nginx_status {
                        stub_status on;
			access_log   off;
			allow 127.0.0.1;
			allow ::1;
			deny all;
                }
}

sudo Configuration

Adapt your /etc/sudoers with:

Debian-snmp ALL=(ALL) NOPASSWD: /etc/snmp/nginx

Adapt your /etc/snmp/snmpd.conf with:

extend nginx /usr/bin/sudo /etc/snmp/nginx
