Consul Dataplane Telemetry

Consul Dataplane collects metrics about its own status and performance. The following external metrics stores are supported:

Consul Dataplane uses the same external metrics store that is configured for Envoy. To enable telemetry for Consul Dataplane, enable telemetry for Envoy by specifying an external metrics store in the proxy-defaults configuration entry or directly in the proxy.config field of the proxy service definition. Refer to the Envoy bootstrap configuration for details.

When Prometheus metrics are used, Consul Dataplane configures Envoy to serve merged metrics through a single endpoint. Metrics from the following sources are collected and merged:

Consul Dataplane
The Envoy process managed by Consul Dataplane
(optionally) Your service instance running alongside Consul Dataplane
