As an aside, we've added breadcrumbs to Apache Camel, ActiveMQ and CXF so that we try to pass breadcrumbs over camel message exchanges, ActiveMQ JMS message flows and CXF web service/REST invocations so its easy to link together log messages, events and messages.
e.g. here's how Camel links the breadcrumbs to Java logging events
then we've a plugin in Fuse to write log statements and camel messages to ElasticSearch (so its kinda like logstash) then we can query and correlate the message flow by a particular breadcrumbId. (We don't yet generate a nice summary record per breadcrumbId with start/stop timings or timings at each endpoint - which would make this metadata easier to query from tools like the Polymeta Dashboard console).
Here's a little screencast showing using the Fuse web tooling which towards the end (maybe 8-10 mins in) shows the log searching and the camel message audit stuff which shows querying by breadcrumb ID - which is really just using ElasticSearch as the back end data store for querying data (via the Lucene query syntax) then the kibana web application for viewing/querying/filtering the data.
It'd be awesome to add better visualisation & reporting of the overall business flows; though at least the basics - storing log messages & camel message flows with bread crumbs is done - with ElasticSearch making it easy to query etc.
If you wanna play with the code, you could clone the Fuse github repo and then create a Fabric. If you wanna noodle the code that does the logging to ElasticSearch in Fuse, its insight-elasticsearch for log events and insight-camel for Camel message auditting.
