Self-Hosted LLM Tracing TCO: Eliminating Per-Trace Cloud Ingestion Overages
DIRECT ANSWER: Deploying self-hosted MIT Langfuse or Arize Phoenix with OpenTelemetry async batching eliminates per-trace SaaS overages and keeps 100% of sensitive prompt payloads inside your VPC.
Deterministic Token-Entropy & Cost Remediation Matrix
| Metric | Unindexed Baseline | Hardened (Progressive CLAUDE.md + Router) |
|---|---|---|
| Trigger Symptom | $450+/mo in cloud trace ingestion fees when logging 20-step agentic tool loops with full prompts | Eliminated (-58% to -64% Discovery Waste) |
| Context Tokens / Turn | 22,800 tokens/turn | 9,580 tokens/turn |
| 5-Engineer Net Monthly Savings | Uncapped Overage Exposure | +$375.00/mo Saved ($4,500.00/yr) |
