How to log failed message in masstransit?
.net, masstransit
Solution
You can implement and configure your own Message Retry Tracking on the bus, so that messages that are failed are passed through your implementation. You can delegate to the default retry tracker and just intercept the events so that you can act on them, or you can implement your own retry tracking if needed.
MessageTrackerFactory is the delegate for configuring, I think the interface is nearby.
Problem
I'm looking for a good solution to log failed message, right after retry limit is exceeded, without having a deal with error queue. What I've found so far: - I can inherit from InMemoryInboundMessageTracker and override IsRetryLimitExceeded, but at this point there no information about message itself except id. - I can implement IInboundMessageInterceptor and get IConsumeContext in Pre/PostDispatch, but at this point there no information about success/fail. So as a solution, I can get IConsumeContext in PreDispatch put it in some sort of a cache then get it out of a cache in IsRetryLimitExceeded when retry limit is exceeded. Methods are called in such order: IsRetryLimitExceeded -> PreDispatch -> PostDispatch So I can't find a good place to remove successfully processed message from a cache. Of course I can use a cache with restricted size but this whole solution seems to be weird. Any thoughts on this matter would be appreciated.
