Subject: Re: How to use lua plugin and Scripts in Traffic server ?
You also need to set your debug tag appropriately when turning on debug.
https://docs.trafficserver.apache.org/en/latest/admin-guide/files/records.config.en.html#proxy-config-diags-debug-tags
For lua plugin , you need to set the debug tags accordingly. e.g.
CONFIG proxy.config.diags.debug.tags STRING .*lua.*
inside records.config
Thanks.
