Retrieving Compute Agents Information


Use the Cloud Analytics Engine DLE API as follows to retrieve information about Compute Agent (CA) Cloud Analytics Engine components known to DLE.

GET /api/v1/compute-agents

Get a list of all CA components known to DLE, with details about their configuration. DLE API clients use this information for activating flow traces, because CA signature information is part of the required parameters for starting a trace (see DLE API POST /api/v1/traces).

Clients can also subscribe to DLE event notifications and learn when DLE discovers new CA components, to know when to issue this request to get the new CA information. See DLE API GET /api/v1/events for details.

Request Format:

  • GET method.

Request Parameters:

  • None.

Response Data (in JSON format):

  • totalSize: (Numeric) Number of CA components for which data is being returned.

  • caList: List of CA components known to DLE, described in Compute Agent Transfer Object.

  • uri: Resource URI for this request.

See Inquiry Compute Agent Data Learning Engine API Example for a sample request and response.

Compute Agent Transfer Object

Table 1 describes the Compute Agent transfer object, the response data to a DLE API request for information about CA components in the network (see GET /api/v1/compute-agents).
