02a064d002f6ffae82ab2d3e047e973054c55235 Mon Sep 17 00:00:00 2001 From: Arjun Rajappa Date: Thu, 25 Jun 2026 14:42:29 +0530 Subject: [PATCH 21/38] feat(otlp-exporter): add config-driven OTLP exporter initialization - Add OTLP config block to Config#initialize with defaults (disabled) - Support config precedence: YAML > env vars > agent discovery > defaults - Add read_otlp_config_from_agent to apply agent-pushed OTLP settings - Replace hardcoded INSTANA_OTLP_ENABLED env-var branch in HostAgentReportingObserver with initialize_otlp_exporter driven by ::Instana.config[:otlp] - Remove debug info log of converted spans before OTLP export - Add tests for config and observer initialization Signed-off-by: Arjun Rajappa --- .../backend/host_agent_reporting_observer.rb | 26 +-

Content-Transfer-Encoding: 8bit - Introduce SpanDataWithEvents wrapper to carry OTel span events without breaking the existing SpanData keyword_init constructor - Add build_error_events: emits exception event (with stacktrace) or error event when span.ec > 0 - Add convert_stack_trace: maps Instana stack frames (c/n/m) to OTel exception.stacktrace newline-separated string - Refactor convert_status → build_status(error_count, error_msg) to decouple status from implicit span state - Implement extract_error_message: searches span[:data][type][:error], truncates to 1024 chars per OTel recommendation - Fix span_name for custom (SDK) spans: read span[:data][:sdk][:name] instead of span[:n] - Extend base_converter_test with coverage for all new paths Signed-off-by: Arjun Rajappa
