nyanlintun/podmeter repository overview

Summary

• PodMeter is a lightweight Go service to measure and compare performance between Istio Ambient and Sidecar modes. It exposes JSON metrics (latency percentiles, memory usage, proxy hops, throughput) at /stats.

Features

• Latency percentiles: p50/p95/p99/p999 and averages
• Resource usage: memory, goroutines, GC stats
• Proxy awareness: detects Istio sidecar vs ambient, tracks proxy hops
• Simple, zero-dependency Go binary; small runtime image

Image

• Repository: nyanlintun/podmeter
• Tags: latest (main), commit SHA (e.g., sha-)
• Platforms: linux/amd64, linux/arm64
• Exposed port: 8080

Quick Start

• Run: docker run --rm -p 8080:8080 nyanlintun/podmeter:latest
• Health: curl http://localhost:8080/⁠ → OK
• Metrics: curl http://localhost:8080/stats⁠ | jq

Kubernetes

• Use the image in your Deployment: image: nyanlintun/podmeter:latest
• Service port: 8080

Endpoints

• GET / — Health check (simple OK)
• GET /stats — JSON with metrics (requests, success rate, latency percentiles, memory, GC, proxy hops, Istio detection, uptime)

Use Cases

• Compare Ambient vs Sidecar overhead
• Benchmark latency/throughput
• Resource/cost analysis for mesh choices
• SRE metrics for pod health
