    Understanding 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 follows:

    (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 Settings (gear) icon towards the bottom of the left sidebar.
    2. Select Organization Settings.
    3. Select Usage in the sidebar.
