Python Client

The client-py Python library provides:

  • A Client class, used to initialize a gRPC secure channel with the Falco gRPC server.
  • Request and Response classes representing the protobuf objects having the same name.

Refer to the example to see how the Python client connects to the Falco gRPC Outputs API and displays the events in JSON.

Currently the Python client has two output formats: the Response class which is the default one and is recommended if the data needs to be processed further with Python or JSON. To enable the JSON output it is sufficient to pass the output_format="json" parameter when instanciating a Client.

  1. Ensure that you have the certificates in the example’s path at /tmp/{client.crt,client.key,ca.crt}.

  2. Create and activate a Python environment with the required dependencies.

  3. From the client-py root directory, run:

    $ python -m examples.get_events -o json
    

    You should see output events starting flowing in depending on the set of rules your Falco instance has.
