StatsD Configuration

Configuration

This plugin is compatible with DB-less mode.

Compatible protocols

The StatsD plugin is compatible with the following protocols:

grpc, grpcs, http, https, tcp, tls, tls_passthrough, udp, ws, wss

Parameters

Here's a list of all the parameters which can be used in this plugin's configuration:

• name or plugin

  string required

  The name of the plugin, in this case statsd.

  • If using the Kong Admin API, Konnect API, declarative configuration, or decK files, the field is name.
  • If using the KongPlugin object in Kubernetes, the field is plugin.

• instance_name

  string

  An optional custom name to identify an instance of the plugin, for example statsd_my-service.

  The instance name shows up in Kong Manager and in Konnect, so it's useful when running the same plugin in multiple contexts, for example, on multiple services. You can also use it to access a specific plugin instance via the Kong Admin API.

  An instance name must be unique within the following context:

  • Within a workspace for Kong Gateway Enterprise
  • Within a control plane or control plane group for Konnect
  • Globally for Kong Gateway (OSS)

• service.name or service.id

  string

  The name or ID of the service the plugin targets. Set one of these parameters if adding the plugin to a service through the top-level /plugins endpoint. Not required if using /services/{serviceName|Id}/plugins.

• route.name or route.id

  string

  The name or ID of the route the plugin targets. Set one of these parameters if adding the plugin to a route through the top-level /plugins endpoint. Not required if using /routes/{routeName|Id}/plugins.

• consumer.name or consumer.id

  string

  The name or ID of the consumer the plugin targets. Set one of these parameters if adding the plugin to a consumer through the top-level /plugins endpoint. Not required if using /consumers/{consumerName|Id}/plugins.
