Re: Use JAVA/CATALINA_OPTS arguments in server.xml
Thanks, Chuck!
This works for defining the port but does not work for the host.
<Member className="org.apache.catalina.tribes.membership.StaticMember"
port="4000" host="${tomcat.member:-localhost}"/>
<Member className="org.apache.catalina.tribes.membership.StaticMember"
port="4000" host="${tomcat.member:-127.0.0.1}"/>
Using either of the above throws the following error,
21-Mar-2024 15:04:58.185 SEVERE [GroupChannel-Heartbeat-1]
org.apache.catalina.tribes.group.interceptors.TcpFailureDetector.memberAlive

Yes, I agree. Can you run under a debugger and observe the value being
set? Or recompile it with a log statement? I don't see much logging in
that class, and I'm not familiar enough with the clustering code to know
where best to enable logging to see the effective configuration.

How old is your version of Tomcat?
This feature dates back to spring of year 2020
https://github.com/apache/tomcat/commit/90b8ff2f330973bbe54dbbe3d702b3111bb781fc
https://github.com/apache/tomcat/commit/6f356df24241db9f655c8adb0c51aea95a2ab05d
Maybe you can test it first in some other more easily observable
place, e.g. in web.xml?
Best regards,
Konstantin Kolinko

I have not defined its value. It works fine if I do, however, I am
expecting it to use the default instead.

What is the value of the system property "tomcat.member"?
