Send Arista logs to Graylog

Hi, I have brought up Graylog as our centralized logging server. But I'm not able to see the logs in Graylog server. Here are the input config:

allow_override_date: true bind_address: 0.0.0.0 expand_structured_data: false force_rdns: false number_worker_threads: 72 override_source: <empty> port: 514 recv_buffer_size: 262144 store_full_message: true 

Is it not parsing the logs? Has anyone done it? Thanks for help.
