CrowdStrike Source

The CrowdStrike Source provides a secure endpoint to receive event data from the CrowdStrike Streams API. It securely stores the required authentication, scheduling, and state tracking information.


The CrowdStrike API documentation is not public and can only be accessed by partners or customers.

The types of events are defined in the Streaming API Event Dictionary.


This Source is available in the Fed deployment.


Before you can connect to event streams, you must contact the CrowdStrike support team to enable the streaming APIs on your customer account. If it's not enabled, your requests will receive HTTP 500 responses.


A CrowdStrike 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 CrowdStrike 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 CrowdStrike.
  5. Collecting. The Source is actively collecting data from CrowdStrike.

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.

Hover your mouse over the status icon to view a tooltip with details on the detected issue.

You must contact CrowdStrike support and enable the Streams API.

A CrowdStrike Source authenticates with an OAuth2 API key. These are created in the Crowdstrike Console under API Clients and Keys. The API token needs the READ privilege for the following properties:

  • Detections
  • Event Streams
  • Hosts
  • Host Groups

Create a CrowdStrike Source

When you create a CrowdStrike 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 Configure a Hosted Collector.

To configure a CrowdStrike Source:

  1. In Sumo Logic, select Manage Data > Collection > Collection
  2. On the Collectors page, click Add Source next to a Hosted Collector.
  3. Select CrowdStrike.

  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:
    • _siemVendor: CrowdStrike
    • _siemProduct: Falcon Endpoint Protection (CNC)
    • _siemFormat: JSON
    • _siemEventID: <metadata.eventype>, where <metadata.eventype> is the value of the field from the JSON event, such as IncidentSummaryEvent or DetectionSummaryEvent.
  7. (Optional) Fields. Click the +Add Field link to 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 in the Fields table schema.
    • orange exclamation point.png An orange triangle with an exclamation point is shown when the field doesn't exist in the Fields table schema. In this case, an option to automatically add 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 it is ignored, known as dropped.
  8. CrowdStrike domain: Provide your CrowdStrike domain, for example,
  9. Client ID: Provide the CrowdStrike Client ID you want to use to authenticate collection requests.
  10. Secret Key. Provide the CrowdStrike API key you want to use to authenticate collection requests.
  11. (Optional) Application ID. To allow for easier tracking of your log ingestion, you can provide a 1 to 15 character identifier to add to your CrowdStrike Audit Logs.

    If no Application ID is provided, a random ID is generated. Any time this ID is changed, the Source will re-read the data stream starting at the beginning.

  12. 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.

TypeReasonRetriesRetry BehaviorHealth Event Name
ThirdPartyConfigNormally 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 applicableThirdPartyConfigError
ThirdPartyGenericNormally due to an error communicating with the third party service APIs.YesThe Source will retry for up to 90 minutes, after which retries will be attempted every 60 minutes.ThirdPartyGenericError
FirstPartyGenericNormally due to an error communicating with the internal Sumo Logic APIs.YesThe Source will retry for up to 90 minutes, after which retries will be attempted every 60 minutes.FirstPartyGenericError

Restarting your Source

If your Source encounters ThirdPartyConfig errors, you can restart it from either the Sumo Logic UI or Sumo Logic API.


To restart your source in the Sumo Logic platform, follow the steps below:

  1. Open the Collection page, and go to Manage Data > Collection > Collection.
  2. Select the source and click the information icon on the right side of the row.
  3. The API usage information popup is displayed. Click the Restart Source button on the bottom left.
  4. Click Confirm to send the restart request.
  5. The bottom left of the platform will provide a notification informing you the request was successful.


To restart your source using the Sumo Management API, follow the instructions below:

  • Method: POST
  • Example endpoint:{collector_id}/sources/{source_id}/action/restart

Sumo Logic endpoints like are different in deployments outside us1. For example, an API endpoint in Europe would begin A service endpoint in us2 (Western U.S.) would begin For more information, see Sumo Logic Endpoints.

JSON configuration 

Sources can be configured using UTF-8 encoded JSON files with the Collector Management API. See how to use JSON to configure Sources for details. 

configJSON ObjectYesContains the configuration parameters for the Source. 
schemaRefJSON ObjectYesUse {"type":"CrowdStrike"} for a CrowdStrike Source.not modifiable
sourceTypeStringYesUse Universal for a CrowdStrike Source.not modifiable

The following table shows the config parameters for a CrowdStrike Source.

nameStringYesType a desired name of the Source. The name must be unique per Collector. This value is assigned to the metadata field _source.modifiable
descriptionStringNonullType a description of the Source.modifiable
categoryStringNonullType a category of the source. This value is assigned to the metadata field _sourceCategory. See best practices for details.modifiable
fieldsJSON ObjectNoJSON map of key-value fields (metadata) to apply to the Collector or Source. Use the boolean field _siemForward to enable forwarding to SIEM.modifiable
domainStringYesYour CrowdStrike domain, for example,
clientIDStringYesThe CrowdStrike Client ID you want to use to authenticate collection requests.modifiable
secretKeyStringYesThe CrowdStrike API key you want to use to authenticate collection requests.modifiable
