SIEM Data Volume Calculator accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- Daily volume = sum(source count x GB/day per source) x growth factor. EPS = daily bytes / average event bytes / 86,400.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Endpoints: 1,400
- Endpoint Volume: 0.03 GB/day
- Servers: 180
- Server Volume: 0.25 GB/day
- Network Devices: 45
- Network Device Volume: 0.8 GB/day
- Cloud Apps: 18
- Cloud App Volume: 1.2 GB/day
- Growth Buffer: 20%
- Average Event Size: 900 bytes
- Peak Multiplier: 4 x
Expected outputs
- Daily SIEM Volume: 173.52 GB
- Monthly Volume: 5,281.51 GB
- Average Event Rate: 2,396.03 EPS
- Peak Event Rate: 9,584.14 EPS
Known limitations
- This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
- Use the result as a planning estimate unless the calculator page states a stricter purpose.
Assumptions
- The calculators use transparent formulas rather than vendor-specific sizing or compliance models.
- Inputs are processed locally in the browser and are not stored by Calwarden.
- Security monitoring scope and retention can be compliance-sensitive; confirm log source coverage with security and compliance owners.
Unit handling
- Endpoints accepts numeric values.
- Endpoint Volume accepts values in GB/day.
- Servers accepts numeric values.
- Server Volume accepts values in GB/day.
- Network Devices accepts numeric values.
- Network Device Volume accepts values in GB/day.
- Cloud Apps accepts numeric values.
- Cloud App Volume accepts values in GB/day.
- Growth Buffer accepts values in %.
- Average Event Size accepts values in bytes.
- Peak Multiplier accepts values in x.
- Daily SIEM Volume is displayed in GB.
- Monthly Volume is displayed in GB.
- Average Event Rate is displayed in EPS.
- Peak Event Rate is displayed in EPS.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
- Input precision follows configured step values where provided.
