# Viewing Usage

The usage of Dremio Cloud within an organization is measured in Dremio Consumption Units (DCUs). DCUs are consumed only when Dremio Cloud engines are running.

## How Usage is Calculated

The number of DCUs consumed by an engine depends on two factors:

• The size of the engine
• How long the engine and its replicas have been running for

DCU consumption for an engine is calculated as `(Total uptime for the engine and its replicas) * (DCU consumption rate for that engine size)`.

Uptime is measured in seconds and has a 60-second minimum.

The DCU consumption rate for each engine size supported in Dremio Cloud is listed in the “Overview” section of Managing Engines.

### Examples

#### Example 1

An organization has two Dremio Cloud engines defined: Engine A and Engine B, where Engine A is a 2XSmall engine, and Engine B is a Medium engine.

Suppose that between 8 a.m. and 9 a.m. one day:

• Engine A had 2 replicas running for 40 minutes each, so it accumulates a total of 80 minutes of engine uptime.
• Engine B had 5 replicas running for 50 minutes each, so it accumulates a total of 250 minutes of engine uptime.

The total usage for Engine A for this hour is `(80/60) * (4 DCUs/hour) = 5.34 DCUs`.

The total usage for Engine B for this hour is `(250/60) * (32 DCUs/hour) = 133.34 DCUs`.

#### Example 2

An organization has one Dremio Cloud engine defined: Engine A, where Engine A is a Medium engine.

Suppose that between 8 a.m. and 9 a.m. one day:

• Engine A had 1 replica running for the entire hour (60 minutes).
• Engine A needed to spin up an additional replica for 30 minutes to tackle a workload spike.

Engine A accumulated a total of 90 minutes of engine uptime, so the total usage for Engine A for this hour is `(90/60) * (32 DCUs/hour) = 48 DCUs`.

## Viewing Usage

On the Usage page, you can view DCU consumption across all the projects in your organization. You can click into an individual project or an engine within a project to drill down into its usage, and apply date filters to view usage data over various date ranges.

Times in the usage data are displayed in UTC.

note:

After a job is completed, it will take one to two hours before the Usage page reflects the number of DCUs that the job used.

To view DCU consumption for your organization:

1. Click the Organization icon in the side navigation bar.

2. Click the Settings icon at the top of the Organization page.

3. Select Usage in the organization settings sidebar.
