Why you need a cloud overselling detector

YABS and sysbench give scores. CloudWorth finds overselling, noisy neighbors, and hard evidence of fake specs.

06 core audit dimensions
01

CPU steal time (st) overselling check

VPS lag often means host overcommit. Microsecond sampling captures steal cliffs, quantifies neighbor contention, and produces technical evidence for support claims.

Steal Rate12.4% (Critical)
02

Disk mislabeling / I/O cache exposé

Blazing for a few seconds, then a cliff? Exposes RAM-cache dressed as NVMe and reveals true sustained throughput and IOPS.

03

Hardware aging vs. price collision

Paying full price for a CPU discontinued years ago? Sees through the virtualization layer to identify the physical chip generation, exposing the quiet downgrade of aged hardware sold at new-gen prices.

Cloud overselling detection FAQ

Quick answers on steal time, VPS overselling, and disk fraud — how to measure, judge, and act.

What is CPU steal time and why does it show overselling?

Steal time (st / %steal in top or mpstat) is the share of time your VM was ready but the hypervisor scheduled other tenants on the physical CPU. Sustained highs (often >5–10%) usually mean overcommit or noisy neighbors — the core signal for overselling detection.

How do I detect if a cloud server / VPS is oversold?

Watch st with top, vmstat, or mpstat at peak hours, then add disk fio and sustained stress tests. CloudWorth packs steal time, disk-cache fraud, hardware generation, and price collision into one probe and builds an audit report in ~10 seconds.

How is CloudWorth different from YABS / sysbench?

YABS and sysbench emphasize benchmark scores. CloudWorth emphasizes evidence and FinOps: quantify steal time, expose disk fraud, spot aged-hardware premiums, and export complaint-ticket PDFs plus downsizing guidance.

Which clouds and OSes are supported? Any dependencies?

Linux (x86_64/ARM64) and Windows Server, including AWS, GCP, Alibaba Cloud, Tencent Cloud, and common VPS hosts. The probe is a zero-dependency single binary — runs, reports, cleans up; never resident.
