We are using a PUB/SUB mechanism with six agents using the same name, so we are relying on the load balancing mechanism of WM. We want only one agent to receive the message. This had been working without issue for 9 months until last week, when we started to get the case where two agents were receiving the message within a few hundred milliseconds of each other. We enriched the sending agent with very precise logging and have determined that the message is sent only a single time.
I have been told that it is not possible to activate filtered logging on the broker, so full logging would need to be enabled and there are millions of other unrelated messages flowing through this same broker. On the scope that we are using, the messaging is very slow - about 2000 per day. So my questions are:
Has anyone see behaviour of this sort? I know that the broker is deprecated, but it is the latest version.
Is it possible to activate logging on the broker, but filtered to one specific scope?
