Description

The camel-micrometer component includes a RoutePolicy, EventNotifiers and a MessageHistory, which provides a set of metrics. I think it would be a great improvement to expand this set, more particularly with metrics on:

• Total count of exchanges completed, per route
• Total count of exchanges failed, per route
• Current count of exchanges inflight, per route

I find these metrics to be highly useful in the context of monitoring camel apps and would assume others do as well.
