Configuring Monitoring to monitor Nginx

Prerequisites

The Nginx plugin requires that you enable the status information handler inNginx. This can be done by downloadingstatus.conf from theGitHub configuration repository and placing it in the Nginx configuration directory (normally/etc/nginx/conf.d/):

(cd /etc/nginx/conf.d/ && sudo curl -O https://raw.githubusercontent.com/Stackdriver/stackdriver-agent-service-configs/master/etc/nginx/conf.d/status.conf)

Alternatively, you can append the contents ofstatus.conf to yournginx.conf file, normally located in one of the following directorieson your VM instance:/etc/nginx,/usr/local/nginx/conf, or/usr/local/etc/nginx.
