From 5537fe85ed65444359bfd066707760d6395fc7a4 Mon Sep 17 00:00:00 2001 From: Mohamed Bassem Date: Mon, 29 Dec 2025 19:11:16 +0200 Subject: feat: Add open telemetry (#2318) * feat: add OpenTelemetry tracing infrastructure Introduce distributed tracing capabilities using OpenTelemetry: - Add @opentelemetry packages to shared-server for tracing - Create tracing utility module with span helpers (withSpan, addSpanEvent, etc.) - Add tRPC middleware for automatic span creation on API calls - Initialize tracing in API and workers entry points - Add demo instrumentation to bookmark creation and crawler worker - Add configuration options (OTEL_TRACING_ENABLED, OTEL_EXPORTER_OTLP_ENDPOINT, etc.) - Document tracing configuration in environment variables docs When enabled, traces are collected for tRPC calls, bookmark creation flow, and crawler operations, with support for any OTLP-compatible backend (Jaeger, Tempo, etc.) * refactor: remove tracing from workers for now Keep tracing infrastructure but remove worker instrumentation: - Remove tracing initialization from workers entry point - Remove tracing instrumentation from crawler worker - Fix formatting in tracing files The tracing infrastructure remains available for future use. * add hono and next tracing * remove extra span logging * more fixes * update config * some fixes * upgrade packages * remove unneeded packages --------- Co-authored-by: Claude --- packages/trpc/index.ts | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'packages/trpc/index.ts') diff --git a/packages/trpc/index.ts b/packages/trpc/index.ts index 555ca3ba..178703f0 100644 --- a/packages/trpc/index.ts +++ b/packages/trpc/index.ts @@ -6,6 +6,7 @@ import type { db } from "@karakeep/db"; import serverConfig from "@karakeep/shared/config"; import { createRateLimitMiddleware } from "./lib/rateLimit"; +import { createTracingMiddleware } from "./lib/tracing"; import { apiErrorsTotalCounter, apiRequestDurationSummary, @@ -86,7 +87,9 @@ export const procedure = t.procedure }); end(); return res; - }); + }) + // OpenTelemetry tracing middleware + .use(createTracingMiddleware()); // Default public procedure rate limiting export const publicProcedure = procedure.use( -- cgit v1.2.3-70-g09d2
