# Retrieve usage metrics over time

> Retrieves usage statistics for your organization over a specified time period. Usage metrics include data ingestion volumes, search query counts, and export activities. The results can be broken down into time slices and optionally compared against previous periods for trend analysis.

      An Application Programming Interface (API) key is a unique identifier. 

      The API Key must be provided as X-BRONTO-API-KEY in headers for the

  - name: context
    description: >
      Context is a REST API resource that allows the retrieval of a specified
      number of log events (default of 100) around 

      a log event of interest, e.g. when a number of log events were returned by
      a previous query and you then decide you 

      want to see the 50 log events before one of those returned log events. Log
      events can be retrieved either before, 

      after, or both before and after the specified log event.
  - name: exports
    description: >
      The Bronto Export API allows you to efficiently download large volumes of
      log data for further analysis.

      The data to be exported can be filtered by entering the search parameters
      \"from\", \"where\" and \"time_range\" as

      per a normal query in the \"search_details\" object.


      To export data the following steps are required:

      1. Create an export using a POST request, which will return an
      \"export_id\", \"status\" and \"progress\".

      2. Use the export id to get the status of the export task by sending a GET
      request,

      which will return \"status\" and \"progress\" with a value of percentage
      completed. When the export is

      completed, the \"status\" will be \"COMPLETE\"

      3. Once the export task has completed you can download your data using
      curl (or similar)

      from the \"location\" URL returned in the GET response.

      Usage is a REST API resource that allows you to easily track your Bronto

      to data ingestion and amount of data searched, and allowing you to drill
      down for a specific dataset over a defined timeframe.
  - name: users
    description: >
      Users are given specific roles, where each role determines the user's
      permissions within the application. Those roles are as follows:

      - "Admin" role has permission for all actions on all entities in the
      application.

      - "Standard" role allows Read/Write and Delete actions on entities in
      non-sensitive areas of the application.

      - "ReadOnly" role allows only read actions and only on entities in
      non-sensitive areas of the application.

            When multiple from_tags are provided, filters on the same tag key
            are evaluated with OR logic, while filters on tags with different
            keys

            are evaluated with AND logic (facet style search). e.g.
