Dropbox Source

The Dropbox Source provides a secure endpoint to receive team events from the Get Events API. It securely stores the required authentication, scheduling, and state tracking information.

Rules

  • JSON is the only supported log format
  • Data is collected in five minute intervals.

Authentication

You'll need a Dropbox App Key, App Secret, and Access Code to provide to Sumo Logic.

To generate these credentials:

  1. Sign in to your Dropbox Business Account.
  2. Create a new app in the App Console.
  3. Open the new app and click Permissions and enable events.read in Team Scopes of the app and then click Submit.
  4. Copy the provided App Key and App Secret values, you'll provide these to the Sumo Logic Dropbox Source and are needed in the next step.
  5. Replace APP_KEY with your App Key in the following URL.

    https://www.dropbox.com/oauth2/authorize?client_id=APP_KEY&token_access_type=offline&response_type=code

  6. Load the modified URL and you'll see the sign in page of Dropbox. Sign in with your Dropbox Business account credentials to obtain the access code. Then click the Allow button. Copy the Access Code to provide to the Sumo Logic Dropbox Source.

States

A Dropbox Source tracks errors, reports its health, and start-up progress. You’re informed, in real-time, if the Source is having trouble connecting, if there's an error requiring user action, or if it is healthy and collecting by utilizing Health Events.

A Dropbox Source goes through the following states when created:

  1. Pending: Once the Source is submitted it is validated, stored, and placed in a Pending state.
  2. Started: A collection task is created on the Hosted Collector.
  3. Initialized: The task configuration is complete in Sumo Logic.
  4. Authenticated: The Source successfully authenticated with Dropbox.
  5. Collecting: The Source is actively collecting data from Dropbox.

If the Source has any issues during any one of these states it is placed in an Error state.

When you delete the Source it is placed in a Stopping state, when it has successfully stopped it is deleted from your Hosted Collector.

On the Collection page, the Health and Status for Sources is displayed. Use Health Events to investigate issues with collection. You can click the text in the Health column, such as Error, to open the issue in Health Events to investigate.

Create a Dropbox Source

When you create a Dropbox Source, you add it to a Hosted Collector. Before creating the Source, identify the Hosted Collector you want to use or create a new Hosted Collector. For instructions, see Create a Hosted Collector.

To configure a Dropbox Source:

  1. In the Sumo Logic web app, navigate to Manage Data > Collection and open the Collection tab. 
  2. On the Collectors page, click Add Source next to a Hosted Collector.
  3. Select Dropbox.

  4. Enter a Name for the Source. The description is optional.

  5. (Optional) For Source Category, enter any string to tag the output collected from the Source. Category metadata is stored in a searchable field called _sourceCategory.
  6. Forward to SIEM. Check the checkbox to forward your data to Cloud SIEM Enterprise.

    When configured with the Forward to SIEM option the following metadata fields are set:
Field Name Value
_siemVendor Dropbox
_siemProduct Dropbox
_siemFormat JSON
_siemEventID {event_type..tag}
  1. (Optional) Fields. Click the +Add link to add custom log metadata Fields.
    • Define the fields you want to associate, each field needs a name (key) and value. 
      • green check circle.png A green circle with a check mark is shown when the field exists and is enabled in the Fields table schema.
      • orange exclamation point.png An orange triangle with an exclamation point is shown when the field doesn't exist, or is disabled, in the Fields table schema. In this case, an option to automatically add or enable the nonexistent fields to the Fields table schema is provided. If a field is sent to Sumo that does not exist in the Fields schema or is disabled it is ignored, known as dropped.
  2. App Key, App Secret, and Access Code. Provide your Dropbox authentication credentials.

  3. Processing Rules. Configure any desired filters, such as allowlist, denylist, hash, or mask, as described in Create a Processing Rule.
  4. When you are finished configuring the Source click Submit.

Error types

When Sumo Logic detects an issue it is tracked by Health Events. The following table shows the three possible error types, the reason the error would occur, if the Source attempts to retry, and the name of the event log in the Health Event Index.

Type Reason Retries Retry Behavior Health Event Name
ThirdPartyConfig Normally due to an invalid configuration. You'll need to review your Source configuration and make an update. No retries are attempted until the Source is updated. Not applicable ThirdPartyConfigError
ThirdPartyGeneric Normally due to an error communicating with the third party service APIs. Yes The Source will retry for up to 90 minutes, after which it quits. ThirdPartyGenericError
FirstPartyGeneric Normally due to an error communicating with the internal Sumo Logic APIs. Yes The Source will retry for up to 90 minutes, after which it quits. FirstPartyGenericError
