Extract the device list through the REST API

The device list includes all device metadata, such as MAC addresses and device IDs. However, you can filter the list of devices with a JSON parser to extract the specific information you want to export. In this example, the device list is retrieved and then filtered with the jq parser to only extract the display name of each device.

curl -s -X POST "https://HOSTNAME/api/v1/devices/search" --header "accept: application/json" --header "Authorization: ExtraHop apikey=YOUR_KEY" --header "Content-Type: application/json" -d "{ \"active_from\": 1, \"active_until\": 0, \"limit\": MAX_DEVICES}" | jq -r '.[] | .display_name'

curl -s -X POST "https://HOSTNAME/api/v1/devices/search" --header "accept: application/json" --header "Authorization: ExtraHop apikey=YOUR_KEY" --header "Content-Type: application/json" -d "{ \"active_from\": 1, \"active_until\": 0, \"limit\": 1000000000}" | jq -r '.[] | select(.analysis == "advanced") | .display_name'

curl -s -X POST "https://HOSTNAME/api/v1/devices/search" --header "accept: application/json" --header "Authorization: ExtraHop apikey=YOUR_KEY" --header "Content-Type: application/json" -d "{ \"active_from\": 1, \"active_until\": 0, \"limit\": 1000000000}" | jq -r '.[] | select(.critical == true) | .display_name'

curl -s -X POST "https://HOSTNAME/api/v1/devices/search" --header "accept: application/json" --header "Authorization: ExtraHop apikey=YOUR_KEY" --header "Content-Type: application/json" -d "{ \"active_from\": 1, \"active_until\": 0, \"limit\": 1000000000}" | jq -r '.[] | select(.cloud_instance_name != null) | .cloud_instance_name'

1. Open a terminal application and run the following command, where REVEAL_X_360_REST_API is the hostname of the RevealX 360 API. This hostname is displayed in RevealX 360 on the API Access page under API Endpoint. The hostname does not include the /oauth2/token:

   HOST="https://REVEAL_X_360_REST_API"

   Copy
2. Run the following command, where YOUR_ID is the ID of the REST API credentials:

   ID="YOUR_ID"

   Copy
3. Run the following command, where YOUR_SECRET is the secret of the REST API credentials:

   SECRET="YOUR_SECRET"

   Copy
4. Run the following command:

   AUTH=$(printf "$ID:$SECRET" | base64 --wrap=0)

   Copy
5. Run the following command:

   ACCESS_TOKEN=$(curl -s \
       -H "Authorization: Basic ${AUTH}" \
       -H "Content-Type: application/x-www-form-urlencoded" \
       --request POST \
        ${HOST}/oauth2/token \
       -d "grant_type=client_credentials" \
       | jq -r '.access_token')

   Copy
6. Run the following command, where MAX_DEVICES is a number large enough to be more than the total number of devices discovered by your system:

   curl -s -X GET -H "Authorization: Bearer ${ACCESS_TOKEN}"  "$HOST/api/v1/devices?active_from=1&active_until=0&limit=MAX_DEVICES" | jq -r '.[] | .display_name'

   Copy

   Tip:

   You can append the select(.analysis == "LEVEL") option to filter results by analysis level. For example, the following command limits the results to include only devices that are selected for advanced analysis: curl -s -X GET -H "Authorization: Bearer ${ACCESS_TOKEN}" "$HOST/api/v1/devices?active_from=1&active_until=0&limit=10000000000" | jq -r '.[] | select(.analysis == "advanced") | .display_name' Copy

   Tip:

   You can append the select(.critical == BOOLEAN) option to filter results by the critical field. For example, the following command limits the results to include only devices that are identified as critical by the ExtraHop system: curl -s -X GET -H "Authorization: Bearer ${ACCESS_TOKEN}" "$HOST/api/v1/devices?active_from=1&active_until=0&limit=10000000000" | jq -r '.[] | select(.critical == true) | .display_name' Copy

   Tip:

   You can append the select(.cloud_instance_name != null) option to filter results by the cloud instance name field. For example, the following command limits the results to include only devices with a cloud instance name: curl -s -X GET -H "Authorization: Bearer ${ACCESS_TOKEN}" "$HOST/api/v1/devices?active_from=1&active_until=0&limit=10000000000" | jq -r '.[] | select(.cloud_instance_name != null) | .cloud_instance_name' Copy

The ExtraHop GitHub repository contains an example Python script that extracts the device list, including all device metadata, and writes the list to a CSV file in the same directory as the script.

1. Go to the ExtraHop code-examples GitHub repository and download the extract_device_list/extract_device_list.py file to your local machine.
2. In a text editor, open the extract_device_list.py file and replace the configuration variables with information from your environment.
   • For sensors and ECA VMs, specify the following configuration variables:

     HOST: The IP address or hostname of the sensor or ECA VM.

     API_KEY: The API key.

     CSV_FILE: The file that contains the list of device groups.

     FILENAME: The file that output will be written to

     LIMIT: The maximum number of devices to retrieve with each GET request

     SAVEL2: Retrieves L2 parent devices. This variable is valid only if you have enabled the ExtraHop system to discover devices by IP address.

     ADVANCED_ONLY: Retrieves only devices that are currently under advanced analysis

     HIGH_VALUE_ONLY: Retrieves only devices that are considered high value

   • For RevealX 360, specify the following configuration variables:

     HOST: The hostname of the RevealX 360 API. This hostname is displayed in the RevealX 360 API Access page under API Endpoint. The hostname does not include the /oauth2/token.

     ID: The ID of the RevealX 360 REST API credentials.

     SECRET: The secret of the RevealX 360 REST API credentials.

     CSV_FILE: The file that contains the list of device groups.

     FILENAME: The file that output will be written to

     LIMIT: The maximum number of devices to retrieve with each GET request

     SAVEL2: Retrieves L2 parent devices. This variable is valid only if you have enabled the ExtraHop system to discover devices by IP address.

     ADVANCED_ONLY: Retrieves only devices that are currently under advanced analysis

     HIGH_VALUE_ONLY: Retrieves only devices that are considered high value

3. Run the following command:

   python3 extract_device_list.py

   Copy

   Note:

   If the script returns an error message that the TLS certificate verification failed, make sure that a trusted certificate has been added to your sensor or console. Alternatively, you can add the verify=False option to bypass certificate verification. However, this method is not secure and is not recommended. The following code sends an HTTP GET request without certificate verification: requests.get(url, headers=headers, verify=False) Copy
