Grafana Pyroscope

Docs: https://grafana.com/docs/pyroscope/latest/

Continuous profiling — flame graphs of CPU, memory, allocations, mutex contention, goroutines.

Prerequisites

• Pyroscope server (OSS) or Grafana Cloud Profiles endpoint
• For Cloud: numeric Pyroscope user (stack id) + API key
• For eBPF via Alloy: root + host PID + Linux ≥ 5.8 with BTF (or RHEL 4.18+)

Instrumentation paths

1. Alloy eBPF (preferred) — auto-instrument, no code change
2. SDK direct push — application calls Pyroscope API
3. SDK → Alloy — SDK posts to pyroscope.receive_http, Alloy forwards
