Use one record per service/pool; use the same units and observation date.

Service / pool / owner: ________________________
Measurement date and period: ___________________
Units: decimal GB/TB or binary GiB/TiB? _________
Data source / dashboard / query: _______________
Application and environment: __________________

CAPACITY
Logical capacity presented to applications: ____
Usable physical pool capacity after overhead: __
Measured physical consumption: ________________
Planning threshold and rationale: _____________
Headroom to threshold = threshold - consumption:
_______________________________________________
Observed net growth per month: _________________
Additional planned net growth per month: _______
Total assumed net monthly growth: ______________
Months to threshold = headroom / total growth: _
If growth is zero/negative, do not divide; describe the trend and scenario.
Purchase/migration/test lead time: ______________
Required contingency time: _____________________
Action date and owner: _________________________

FICTIONAL EXAMPLE - not a universal threshold
Usable pool 100 TB; consumed 62 TB; chosen threshold 80 TB.
Headroom 80 - 62 = 18 TB.
At 3 TB/month net growth: 18 / 3 = 6 months to threshold.
With another 2 TB/month planned: 18 / (3+2) = 3.6 months.
Assumes linear growth and a consistent physical-capacity boundary.
Review snapshot, replication, compression, reclamation, and reserved-space
behavior. Verify unusual changes before extrapolating them.

SERVICE AND RECOVERY
Latency / throughput / IOPS expectations: _______
Retention and deletion approval owner: _________
Recovery point objective (data loss in time): ___
Recovery time objective (time to usable service):
_______________________________________________
Last restore test / dataset / isolated location:
_______________________________________________
Recovered point and observed data age: _________
Full time including restore and validation: ____
Application integrity result / evidence: _______
Key and configuration access verified? _________
Outstanding recovery action: ___________________

COST ALLOCATION
Period, currency, and included shared costs: ____
Basis (average consumption, reservation, tier...):
_______________________________________________
Measurement method and sources: ________________
Team quantities / total / allocated amounts: ___
Reconciliation: allocations sum to included cost?
_______________________________________________
Fictional example: $1,200 shared monthly cost; A=6 TB and B=4 TB average
consumption. A=6/10 x $1,200=$720; B=4/10 x $1,200=$480.
This internal allocation rule can differ from provider invoice meters.
