Socket Audit Device

The socket audit device writes to a TCP, UDP, or UNIX socket.

Warning: Due to the nature of the underlying protocols used in this device there exists a case when the connection to a socket is lost a single audit entry could be omitted from the logs and the request will still succeed. Using this device in conjunction with another audit device will help to improve accuracy, but the socket device should not be used if strong guarantees are needed for audit logs.

Enabling

Enable at the default path:

$ vault audit enable socket

Supply configuration parameters via K=V pairs:

$ vault audit enable socket address=127.0.0.1:9090 socket_type=tcp
