uWSGI Input Plugin

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

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Read uWSGI metrics.
[[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"
