Curious to hear what people have found works well for monitoring production Axon applications from an operations perspective, as distinct from a business process perspective.
There are a bunch of JVM-level things you can monitor independently of Axon, but have people found it valuable to keep track of Axon-specific statistics like event / command rates, number of active sagas, number of scheduled events, states of aggregates, etc.? If so, what does your monitoring setup look like? Do you maintain an operations-centric read model in a database alongside the read model you use for your business queries, do everything with log analysis, or something else?
