Changes

Features

• :sparkles:Add TLS security profile support for core interceptors (#2019)

Core interceptors now honor the TLS security profile injected by the Tekton operator via TLS_MIN_VERSION, TLS_CIPHER_SUITES, and TLS_CURVE_PREFERENCES environment variables, allowing cluster-wide TLS policy enforcement on OpenShift.

• :sparkles: feat(metrics): Migration from OpenCensus to OpenTelemetry (#1934)

Migrated metrics from OpenCensus to OpenTelemetry.

ACTION REQUIRED:

1. Configuration key change
   Replace metrics.backend-destination with metrics-protocol in your config-observability-triggers ConfigMap.
   Prometheus export remains the default — no change needed if you were not customizing observability.

2. Infrastructure metric renaming
   Infrastructure metrics (workqueue, K8s client) have been renamed from the
   tekton_triggers_controller_ prefix to standard Knative/OpenTelemetry namespaces.

   ┌──────────────────────────────────────────────────────────┬───────────────────────────────────────────────────┐
   │ Old Metric Name (OpenCensus) │ New Metric Name (OpenTelemetry) │
   ├──────────────────────────────────────────────────────────┼───────────────────────────────────────────────────┤
   │ tekton_triggers_controller_workqueue_depth │ kn_workqueue_depth │
   │ tekton_triggers_controller_workqueue_adds_total │ kn_workqueue_adds_total │
   │ tekton_triggers_controller_workqueue_queue_latency_* │ kn_workqueue_queue_duration_seconds_* │
   │ tekton_triggers_controller_workqueue_work_duration_* │ kn_workqueue_process_duration_seconds_* │
   │ tekton_triggers_controller_workqueue_unfinished_work_* │ kn_workqueue_unfinished_work_seconds │
   │ tekton_triggers_controller_workqueue_retries_total │ kn_workqueue_retries_total │
   │ tekton_triggers_controller_client_latency │ http_client_request_duration_seconds_* │
   │ tekton_triggers_controller_client_results │ kn_k8s_client_http_response_status_code_total │
   └──────────────────────────────────────────────────────────┴───────────────────────────────────────────────────┘

3. Sink counter metrics renamed

   ┌──────────────────────────────────────────┬────────────────────────────────────────────┐
   │ Old Metric Name (OpenCensus) │ New Metric Name (OpenTelemetry) │
   ├──────────────────────────────────────────┼────────────────────────────────────────────┤
   │ eventlistener_event_received_count │ eventlistener_event_received_total │
   │ eventlistener_triggered_resources │ eventlistener_triggered_resources_total │
   └──────────────────────────────────────────┴────────────────────────────────────────────┘

4. All other metric names are unchanged
   controller_eventlistener_count, controller_triggerbinding_count,
   controller_triggertemplate_count, controller_clustertriggerbinding_count,
   controller_clusterinterceptor_count, eventlistener_http_duration_seconds
