Client Profile: A mid-market B2B SaaS platform running a unified commercial observability stack across its production environment.
Summary: A forensic FinOps audit found the monitoring platform was costing more than the production databases it watched.
The Problem Architecture
Cloud spend was growing faster than revenue, and the engineering leadership assumed the cause was compute or storage. A forensic FinOps audit was commissioned to find where the budget was actually going.
Technical Intervention & Approach
The audit treated every line item in the cloud bill as a finding to be justified, not an assumed cost of doing business, including the observability and telemetry platform itself. Spend was reconstructed against actual usage, not list pricing, to find where the organization was paying for capability nobody was using.
Observability Cost Exposure Matrix
| Telemetry Vector | Pre-Audit Spend Share | Root Cost Driver | Post-Remediation Target |
|---|---|---|---|
| Raw span logging | 28% of cloud compute | Default 30-day hot retention on debug-tier spans | Edge-sampled, S3 cold storage tier |
| High-cardinality metrics | 19% of ingestion bill | Per-user and per-request labels on default production metrics | Restricted to sampled debug-tier tags |
| Dashboard and alert sprawl | 15% of paid capacity | Orphaned rules with zero references in the audit window | Quarterly deprecation review |
| Cumulative telemetry burn | 22% to 28% of gross cloud spend | Unaudited default configuration compounding over time | Permanent reduction, no loss of incident coverage |
Measurable Outcomes & Verified ROI
The telemetry platform alone accounted for 22 to 28 percent of total cloud spend, more than the production databases it was monitoring. Rightsizing the observability stack and renegotiating its licensing became the single largest cost-reduction lever in the engagement, ahead of any compute or storage optimization.

Architectural Lessons & FAQs
Q: What is the most commonly overlooked cost in a cloud FinOps audit?
Proprietary observability and telemetry platforms, which routinely run 22 to 28 percent of total cloud spend, often exceeding the cost of the production infrastructure being monitored.
