14-9: Observability & MTTR Economics
The prohibitive cost of blind deployments and the ROI of distributed tracing vs log ingestion bills.
🎯 What You'll Learn
- ✓ Model MTTR cost vectors
- ✓ Calculate tracing payload overhead
- ✓ Determine log ingestion ROI
The Math of the Blind Outage
Mean Time To Resolution (MTTR) consists of two phases: 1) Identification (What broke?) and 2) Remediation (Fixing it). Without distributed tracing, 90% of MTTR is spent blindly searching log files.
If an ecommerce checkout is down during Black Friday, generating $100/minute in lost revenue, a logging tool that reduces Identification time from 40 minutes to 3 minutes yields an immediate $3,700 ROI on that single incident.
However, ingesting 100% of telemetry data into Datadog or Splunk creates ruinous billing. FinOps requires "Aggressive Sampling"—dropping 95% of successful trace data and keeping 100% of error traces.
