ESTIMATE
Your indicative sizing.
| Source | Units | Avg EPS |
|---|---|---|
| Total | 0 |
These defaults drive every calculation above. They are indicative, not a quote.
- · Average event size: 500 bytes
- · Peak factor: ×2
- · Per user: 0.1 EPS
- · Month: 30 days
- GB/day = total EPS × event size × 86,400 ÷ 1e9
Indicative sizing only — actual EPS varies by logging configuration, verbosity, and traffic. Talk to an engineer for a precise assessment.
