Nginx Stream STS Input Plugin

This plugin gathers Nginx status using external virtual host traffic status module - https://github.com/vozlt/nginx-module-sts. This is an Nginx module that provides access to stream host status information. It contains the current status such as servers, upstreams, caches. This is similar to the live activity monitoring of Nginx plus. For module configuration details please see its documentation.

Telegraf minimum version: Telegraf 1.15.0

Configuration

[[inputs.nginx_sts]]
  ## An array of ngx_http_status_module or status URI to gather stats.
  urls = ["http://localhost/status"]

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

  ## 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
