How to configure logstash to pick (not receive) data

Hi all,
i have two servers with these features:

  1. Server1: collects data with Logstash. The data can be saved locally
  2. Server2 : takes the data from Server1

The communication can be only from Server2 to Server1 in HTTPS: Server1 cannot start a communication with Server2. In Server2 i want to use another logstash to picks the data from Server1, but i have no idea how to do it.
Is it possible?Any suggestion?
