Does Kong supports Active "TCP" health checks?

1

Is TCP only for passive health checks or does it also support ACTIVE health check?

From the docs:

You can use the healthchecks.active.type field to specify whether to perform HTTP or HTTPS probes (setting it to "http" or "https" ), or by simply testing if the connection to a given host and port is successful (setting it to "tcp" ).

But again there is a Note:

Note: Active health checks currently only support HTTP/HTTPS targets. They do not apply to Upstreams assigned to Services with the protocol attribute set to “tcp” or “tls”.
