Hi, Thanks for the feedback! Your points are well received.
Attached are the broker xml files: both are using Static Connectors:
- Producer sends messages to primary_UDN_1 server
- Consumer_UDN consumes all message types from primary_UDN_1 server
- primary_UDN_1 server forwards messages to primary_VM_2 server
- Consumer_VM consumes all message types from primary_VM_2 server
- Consumer_UDN and Consumer_VM are the same app; just different instances with
configurations allowing connecting to different Artemis servers
GOAL: Specify messages types to be forwarded from primary_UDN_1 server f to
primary_VM_2 server. This is to reduce traffic from primary_UDN_1 server f to
primary_VM_2 server and hope to improve performance.
Added address name="PositionReport“, as shown below in attempt to forward only
PositionReport to VM node – but all messages still got forwarded from
primary_UDN_1 server f to primary_VM_2 server:
<address name="PositionReport">
<anycast/>
</address>
QUESTION: How to configure so that primary_UDN_1 server would only forward
certain message, such as PositionReport, to primary_VM_2 server?
Regards,
Tin (Tien) Lai

I'm still confused. There's multiple broker configurations in the zip and
questions about both static and dynamic discovery. For the sake of clarity, can
we focus on just *one* issue? If possible, provide configuration for either
static or dynamic discovery (i.e. not both) and ask questions that only deal
with that particular configuration.
Also, please do not continue sending pptx files. Please use a more ubiquitous
file format (e.g. txt, pdf, etc.), or better yet, just describe your use-case
and the problem you're seeing directly in the body of the email as is
customarily done on this mailing list. Folks providing support on this mailing
list are doing so on a volunteer basis so it helps when folks needing support
ask questions which are clear and concise as possible. Thanks!
Justin
