Wildfly 10 not load balancing to other host

[hfluz]

I followed this example, but I created the backend3 server in a slave host. The load balancer is not able to balance to the slave host.

I posted about this issue in stackoverflow and wildfly forum, but I had no luck so far.

Hi @hfluz, did you end up in any success ?

@GregoryOrciuch @hfluz Well, Radoslav's point is left without any reaction. In general, these are good checkpoints to go through:

• does the load-balancer Wildfly see the worker nodes on the protocol://address:port they report to it?
• aren't there multiple workers with the same jvmRoute (i.e. Undertow's instance-id)?
• can all the workers see the Wildfly balancer on the address and port it advertises?

One might switch the load balacner Wildfly into debug mode to see exactly the datagrams being send to the UDP multicast for the workers to see.

Anyway, let's take it to the JBoss forum, if you don't mind. I'll kindly ask you to review the addresses worker nodes bind to and report to the balancer. If your workers report e.g. ajp://127.0.0.1:8009, then obviously, balancer residing on a different machine cannot contact them. Last but not least,

• here is a dead-simple example without any domain and host controllers, relying solely on simple standalone.sh. Might be useful for debugging.
• here is the Adevertize utility you might use on worker nodes to see if they actually receive balancer's datagrams on a particular combination of UDP port, multicast address and interface.

Cheers -K-

Hi @GregoryOrciuch, I wasn't able to make it work. I want to try again against JBoss EAP 7, but I haven't been having enough time lately. I'll consider @Karm points next time, but I'm 90% sure that I checked them last time I tried.
