Retention & storage calculator
Work out the disk your traces, logs and metrics need for their retention periods, after compression.
How it works
Each signal keeps its daily volume for its own retention period. Compression shrinks it, extra copies multiply it, and headroom keeps space free for merges and spikes.
disk = Σ(daily × days) ÷ compression × copies × (1 + headroom)Questions
What compression should I expect?
Columnar stores like ClickHouse often compress telemetry 5 to 15 times.
Why add headroom?
Databases need free space to merge data, and traffic spikes fill disks faster than averages suggest.
