uWSGI Input Plugin

The uWSGI input plugin gathers metrics about uWSGI using its Stats Server.

Configuration

[[inputs.uwsgi]]
  ## List with urls of uWSGI Stats servers. Url must match pattern:
  ## scheme://address[:port]
  ##
  ## For example:
  ## servers = ["tcp://localhost:5050", "http://localhost:1717", "unix:///tmp/statsock"]
  servers = ["tcp://127.0.0.1:1717"]

  ## General connection timeout
  # timeout = "5s"
