Filebeat HAProxy module does not parse tcplog format

Hi,

I'm trying to use the HAProxy module of Filebeat with a TCP frontend in HAProxy but the grok does not seem to work with the log lines generated by the option tcplog of HAProxy.

This GitHub issue mentions that the option tcplog should be supported by Filebeat.

Here is an example of a log line generated by HAProxy :

haproxy[105122]: 1.1.1.1:16625 [27/Apr/2022:16:08:23.339] v4-https v4-server-pool/server01 1/0/1043 28944 CD 2/2/1/0/0 0/0

Regards
