Datadog APM log analysis ( -day window, → )【免费下载链接】langfuse Open source AI engineering platform: LLM evals, observability, metrics, prompt management, playground, datasets. Integrates with OpenTelemetry, LangChain, OpenAI SDK, LiteLLM, and more. YC W23项目地址: https://gitcode.com/GitHub_Trending/la/langfuseSource: APM spans withresource_name:process queue-nameacross EU and US.Volume error rate —RegionTotal spansErrorsError rateEU (prod-eu)%US (prod-us)%Hotspots — concentrated on ~ projectserrors break down by(projectId, error.message):ProjectIdErrorsDominant causeprojectIderror message( ) others.........Optional: contrast with another subsystem if relevant — e.g. Unlike blob storage, PostHog has multiple distinct root causes — not one hotspot pattern.Root cause by error class1.error message— errors, projects2–4 sentences explaining what this error class actually is at the implementation level (which library, which call site). Then list candidate causes in order of likelihood. Mark which ones are confirmed by the data vs. speculative.2.error message— errors, mostly projects3.....Use this slot when a class is asymptomof another class rather than an independent bug — call it out so suggested patches dont double-count.Suggested patchesP0 — one-line summary, e.g. Auto-disable integrations on persistentauth failures Why this is P0 — what noise it kills, what data it stops corrupting, what unblocks downstream work.// relative path from repo root // Short code sketch (5–20 lines). It does not need to compile — // it must communicate the shape of the change.P0 —...P1 — smaller / less urgent fixP2 —E.g. a Prisma pool sizing issue surfaced incidentally by this analysis but not the original bug. Call it out with its own section so it doesnt get lost.Regional split explanation (only if relevant)One paragraph explaining why EU vs. US asymmetry exists — usually not an infra bug, just where the affected tenants happen to live.Dashboards:EU APM:US APM:(logs / metrics / monitor links as relevant)骨架中的两处细节值得注意一是错误簇小节专门预留了 N. Symptom of upstream failure 这个槽位用于标记某类错误其实是另一类错误的症状而非独立 bug防止后续补丁建议重复计数二是 P2 槽位被明确定义为顺带发现如调试 PostHog 时发现的 Prisma 连接池问题给它独立小节以避免在工单讨论中被淹没。 ## 四、逐段解析模板字段从哪里来 ### 4.1 Headerresource_name:process queue-name 的命名约定不是凭空写的 模板要求 Header 写明数据源示例中给出的 APM 过滤条件 resource_name:process queue-name 直接对应仓库中的埋点实现。以 PostHog 集成为例[worker/src/queues/postHogIntegrationQueue.ts](https://link.gitcode.com/i/b7e946a9674e81918082dd17616da421) 中的 processor 用 instrumentAsync 包裹了任务处理逻辑 ts return await instrumentAsync( { name: process posthog-integration-project, startNewTrace: true, spanKind: SpanKind.CONSUMER, }, async () { ... } );【免费下载链接】langfuse Open source AI engineering platform: LLM evals, observability, metrics, prompt management, playground, datasets.
