Frontend Proxy (Envoy)
The frontend proxy is used as a reverse proxy for user-facing web interfaces such as the frontend, Jaeger, Grafana, load generator, and feature flag service.
Enabling OpenTelemetry
NOTE: Only non-synthetic requests will trigger the envoy tracing.
In order to enable Envoy to produce spans whenever receiving a request, the following configuration is required:
static_resources:
listeners:
- address:
socket_address:
address: 0.0.0.0
port_value: ${ENVOY_PORT}
filter_chains:
- filters:
- name: envoy.filters.network.http_connection_manager
typed_config:
'@type': type.googleapis.com/envoy.extensions.filters.network.http_connection_manager.v3.HttpConnectionManager
codec_type: AUTO
stat_prefix: ingress_http
tracing:
provider:
name: envoy.tracers.opentelemetry
typed_config:
'@type': type.googleapis.com/envoy.config.trace.v3.OpenTelemetryConfig
grpc_service:
envoy_grpc:
cluster_name: opentelemetry_collector
timeout: 0.250s
service_name: frontend-proxy
clusters:
- name: opentelemetry_collector
type: STRICT_DNS
lb_policy: ROUND_ROBIN
typed_extension_protocol_options:
envoy.extensions.upstreams.http.v3.HttpProtocolOptions:
'@type': type.googleapis.com/envoy.extensions.upstreams.http.v3.HttpProtocolOptions
explicit_http_config:
http2_protocol_options: {}
load_assignment:
cluster_name: opentelemetry_collector
endpoints:
- lb_endpoints:
- endpoint:
address:
socket_address:
address: ${OTEL_COLLECTOR_HOST}
port_value: ${OTEL_COLLECTOR_PORT}
Where OTEL_COLLECTOR_HOST and OTEL_COLLECTOR_PORT are passed via environment
variables.
