Monitoring

Cloudflare Workers observability with logging, Analytics Engine, Tail Workers, metrics, and alerting. Use for monitoring, debugging, tracing, or encountering log parsing, metric aggregation, alert configuration errors.

Query and explore distributed traces in Grafana Tempo. Use when a user asks to pull tracing data for analysis.

This skill provides AWS cost optimization, monitoring, and operational best practices with integrated MCP servers for billing analysis, cost estimation, observability, and security assessment.

Structured logging, metrics, distributed tracing, and alerting strategies

Use when adding logging, metrics, tracing, or alerting to applications. Covers structured logging, Prometheus metrics, OpenTelemetry tracing, and alerting strategies.

Comprehensive observability skill for monitoring, logging, distributed tracing, alerting, and SLI/SLO implementation across distributed systems. Includes dashboard generation, alert rule creation, error budget calculation, and metrics analysis. Use when implementing monitoring stacks, designing alerting strategies, setting up distributed tracing, or defining SLO frameworks.

Use when adding observability to LLM applications with Langfuse. Covers tracing, evaluation, prompt management, and cost tracking for self-hosted deployments.

Guidelines for structured logging, distributed tracing, and debugging patterns across languages. Covers logging best practices, observability, security considerations, and performance analysis.

ClickHouse analytics and Grafana dashboard configuration for Vigil Guard v2.0.0 monitoring. Use when querying logs, analyzing 3-branch detection metrics, creating dashboards, investigating events, working with n8n_logs database, managing retention policies, or monitoring branch performance (branch_a_score, branch_b_score, branch_c_score).

Setting up Prometheus metrics, OpenTelemetry tracing, and health endpoints for Nais applications

High-performance structured JSON logging for Node.js. Use when building production APIs that need fast, structured logs for observability platforms (Datadog, ELK, CloudWatch). Provides request logging middleware, child loggers for context, and sensitive data redaction. Choose Pino over console.log for any production TypeScript backend.

Debug LangChain and LangGraph agents by fetching execution traces from LangSmith Studio. Use when debugging agent behavior, investigating errors, analyzing tool calls, checking memory operations, or examining agent performance. Automatically fetches recent traces and analyzes execution patterns. Requires langsmith-fetch CLI installed.

Observability patterns for Python applications. Triggers on: logging, metrics, tracing, opentelemetry, prometheus, observability, monitoring, structlog, correlation id.

Manage concurrent background processes using tmux. Use when spawning dev servers, running long-running tasks, monitoring multiple processes, or capturing output from background commands without blocking the main session.

This skill deploys monitoring stacks, including Prometheus, Grafana, and Datadog. It is used when the user needs to set up or configure monitoring infrastructure for applications or systems. The skill generates production-ready configurations, implements best practices, and supports multi-platform deployments. Use this when the user explicitly requests to deploy a monitoring stack, or mentions Prometheus, Grafana, or Datadog in the context of infrastructure setup.

This skill automates the setup of distributed tracing for microservices. It helps developers implement end-to-end request visibility by configuring context propagation, span creation, trace collection, and analysis. Use this skill when the user requests to set up distributed tracing, implement observability, or troubleshoot performance issues in a microservices architecture. The skill is triggered by phrases such as "setup tracing", "implement distributed tracing", "configure opentelemetry", or "add observability to microservices".
