About This Tool

This tool ingests Ceph metrics from monitors, OSDs, and placement groups via configured endpoints to compute a cluster health score and current capacity usage. It connects to the manager API surface and returns a normalized view that supports operations workflows.
Core logic evaluates health using metrics such as OSD up/in, recovery progress, PG states, IOPS latency, and pool usage. It applies weighted penalties to degraded conditions and caps the score between 0 and 100 to provide a single, actionable signal.
Audience and value: storage admins, SREs, and cloud operators gain a unified signal to guide remediation, capacity planning, and alert tuning. Use cases include pre-incident checks, capacity forecasting, and post-incident RCA.
Advanced features include historical trend export, multi-cluster aggregation, per-pool breakdown, threshold-driven alerts, and export-ready JSON. The tool emphasizes correctness, repeatability, and integration readiness without relying on UI components.

Frequently Asked Questions

Find Quick Answers

How is the health score calculated?

The health score is a 0–100 metric computed from penalties assigned to degraded conditions, high latency, active recoveries, and skewed pool usage. Weights are configurable to reflect cluster priorities and risk tolerance.

What inputs are required?

Required inputs include cluster_name and monitor_endpoints. Optional inputs cover authentication method, TLS enablement, and threshold definitions. Missing required inputs produce explicit output indicators and nofalse positives.

Can it aggregate data across multiple Ceph clusters?

Yes. The tool supports multi-cluster aggregation, enabling a unified health view across regions or environments. It can export per-cluster results and provide a combined health score with drill-downs.

What happens if Ceph metrics are temporarily unavailable?

If data is partial or endpoints are unreachable, the tool returns partial outputs with a degraded health_state and flags the missing data as indicators for remediation and retry.
