Summary

Add telemetry_extended_heartbeat_interval to the sidecar's SessionConfig and FFI
layer so that callers (e.g. PHP tracer) can configure the extended heartbeat interval.

The telemetry worker already supports this field in its Config struct, but the sidecar
was not passing it through from SessionConfig -> modify_telemetry_config. This meant
sidecar consumers could not control the cadence of app-extended-heartbeat events.

Changes:

  • datadog-sidecar/src/service/mod.rs: add telemetry_extended_heartbeat_interval: Duration to SessionConfig
  • datadog-sidecar/src/service/sidecar_server.rs: set cfg.telemetry_extended_heartbeat_interval in modify_telemetry_config
  • datadog-sidecar-ffi/src/lib.rs: add telemetry_extended_heartbeat_interval_millis: u64 param to ddog_sidecar_session_set_config

…sionConfig

Add telemetry_extended_heartbeat_interval to the sidecar's SessionConfig
and FFI so that callers (e.g. PHP) can configure the extended heartbeat
interval. The telemetry worker already supports this field in its Config
but the sidecar was not passing it through.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The ExtendedHeartbeat lifecycle action was wrapping the payload in
Payload::AppStarted instead of Payload::AppExtendedHeartbeat, causing
it to serialize as "app-started" instead of "app-extended-heartbeat".

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add telemetry_extended_heartbeat_interval_millis argument (86400000ms
= 24h default) to both ddog_sidecar_session_set_config calls in the
sidecar FFI test.
