Capacity Forecast

The Capacity Forecast analytic determines the “time‐to‐zero” period for an entity’s key metrics to reach capacity using trend estimates based on long‐term historical usage data.It flags each key metric whose time‐to‐zero period is less than specified thresholds.

Before you can begin analyzing for capacity forecasting, you must collect at least three days’ worth of data. The Integration cannot access capacity information from before the integration was installed.

Capacity Forecast analyzes the following metrics to provide capacity reporting and planning information for the Integration.

Compression Efficiency

A ratio of effective capacity to physical capacity. It shows how effectively you are leveraging your physical capacity.

Avg Free Effective Capacity

The average amount of effective capacity available for use, based on compression efficiency.

Avg Free Usable Capacity

The average amount of capacity available for use.

Max Free Effective Capacity

The maximum amount of effective capacity available for use, based on compression efficiency.

Max Free Usable Capacity

The maximum amount of usable capacity available for use, based on compression efficiency.

Max % Free Capacity

The maximum percentage of space free on this volume

Min Free Effective Capacity

The minimum amount of effective capacity available for use, based on compression efficiency.

Min Free Usable Capacity

The minimum amount of usable capacity available for use, based on compression efficiency.

Min % Free Capacity

The minimum percentage of space free on this volume

Avg % Free Capacity

The average percentage of space free on this volume

Avg % Utilized Capacity

The average percentage of space used on this volume

Total Effective Capacity

The total effective capacity available for use (as reported by the device). This is equal to the total physical disk space if this device has no compression, deduplication, thin provisioning etc. enabled.

Total Usable Capacity

The total usable space available to this volume. Usable space is computed by excluding any overhead e.g. RAID, and is equivalent to running the shell command "df".

Avg Used Effective Capacity

The average amount of disk space effectively used. This is equal to used physical disk space if this device has no compression, deduplication, thin provisioning etc. enabled.

Avg Used Usable Capacity

The average used usable space used on this volume. Usable space is computed by excluding any overhead e.g. RAID, and is equivalent to running the shell command "df".
