SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires requests, and includes scripts (resource) components.

What problem does it solve?

This Skill helps you diagnose service issues by querying Prometheus metrics and analyzing resource usage across your applications.

Core Features & Use Cases

  • Automated monitoring checks: Query CPU, memory, load, and heap metrics to assess service health.
  • Live metric queries: Pull current values using Prometheus PromQL via the provided scripts.
  • Use Case: When a service is experiencing latency, run Prometheus queries to compare CPU usage and memory to historical baselines and generate a concise health report.

Quick Start

Run Prometheus queries with the provided scripts, for example: uv run prometheus.py 'sum(rate(container_cpu_user_seconds_total{image!="",application="your_app"}[30s])) by(application) * 100' Then use the output to determine if the service health is degraded.

FAQPage Schema
How do I query Prometheus metrics to diagnose service health issues?

Query Prometheus metrics using PromQL to diagnose service health by retrieving CPU usage, memory usage, load, and heap metrics. Execute prometheus.py with PrometheusUtil to fetch the latest values and compare them against baselines to assess whether resource consumption indicates degraded service performance.

What metrics can I monitor with Prometheus for service troubleshooting?

Prometheus monitoring supports CPU usage, CPU quota, memory usage, memory limits, load average, HeapUsed, and HeapMax metrics. These metrics apply to application-labeled services in Prometheus-monitored environments and enable rapid identification of resource bottlenecks causing latency or performance issues.

Can I automate health checks by querying Prometheus metrics?

Yes, automated monitoring checks query Prometheus metrics to assess service health by pulling current CPU, memory, load, and heap values via PromQL. The Skill constructs PromQL queries, executes them through PrometheusUtil, and generates a concise health report for rapid issue diagnosis.

Do I need a Prometheus-monitored environment to use metric queries for diagnostics?

Yes, this Skill requires services labeled with application metadata within a Prometheus-monitored environment. The Skill queries existing Prometheus instances using PromQL and applies only to environments where metrics are already collected and accessible.

How do PromQL queries help identify CPU and memory bottlenecks?

PromQL queries retrieve live CPU and memory metrics, allowing you to compare current resource usage against historical baselines. This comparison reveals whether elevated CPU or memory consumption correlates with service latency, enabling targeted performance diagnosis without manual log inspection.
