nginx [engine x] is a HTTP and converse intermediary worker, a mail intermediary worker, and a nonexclusive TCP/UDP intermediary worker, initially composed by Igor Sysoev. For quite a while, it has been running on numerous intensely stacked Russian destinations including Yandex, Mail.Ru, VK, and Rambler. As per Netcraft, nginx served or proxied 23.21% busiest destinations in December 2020. Here are a portion of the examples of overcoming adversity: Dropbox, Netflix, WordPress.com, FastMail.FM. 

By default telegraf we have got the telegraf.d directory on /etc/telegraf/telegraf.d in this path, You need to create a nginx.conf configuration file and add the following nginx plugin syntax by following the given command.

 

sudo vim /etc/telegraf/telegraf.d/nginx.conf

Paste the given code to enable the Nginx plugin in telegraf.

 

# Read Nginx's basic status information (ngx_http_stub_status_module)
[[inputs.nginx]]
  ## An array of Nginx stub_status URI to gather stats.
  urls = ["http://localhost/server_status"]

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

  ## HTTP response timeout (default: 5s)
  response_timeout = "5s" 

Here you can uncomments the other parameter to use the username and password for Nginx monitoring user as per your requirement, Save and exit from the vim text editor.

You need to restart the Telegraf service to get new changes for Nginx metric in prometheus, Use the following command for the same.

©©sudo systemctl restart telegraf
