Nginx is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. For more information visit nginx.org.
This functionality is only available for agents running on Linux. It is not available on Windows.
Discovery

- Searching instance names for nginx
- Checking for ports opened to 80 or 443 via firewall rules
To see the metrics for Nginx, do the following:
-
In the Google Cloud console, go to the Dashboards page:
If you use the search bar to find this page, then select the result whose subheading is Monitoring.
- Select the Nginx dashboard from the list.
Configuring Monitoring to monitor Nginx
After you install the monitoring agent, use the following instructions to configure the Nginx plugin on your instances.
Prerequisites
The Nginx plugin requires that you enable the status information handler in
Nginx. This can be done by downloading status.conf
from the GitHub 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 of
status.conf
to your nginx.conf
file, normally located in one of the following directories
on your VM instance:
/etc/nginx
, /usr/local/nginx/conf
, or /usr/local/etc/nginx
.
Reload the Nginx configuration by running:
sudo service nginx reload
Enabling the Nginx monitoring plugin
On your VM instance, download nginx.conf
from the GitHub configuration repository
and place it in the directory /etc/stackdriver/collectd.d/
:
(cd /etc/stackdriver/collectd.d/ && sudo curl -O https://raw.githubusercontent.com/Stackdriver/stackdriver-agent-service-configs/master/etc/collectd.d/nginx.conf)
After adding the configuration file, restart the monitoring agent by running the following command:
sudo service stackdriver-agent restart
For more information on the collectd
nginx
plugin, see
