We have been playing around with Brave(Java implementation of Zipkin) and successfully added tracing for REST and database calls. We would like to also add RabbitMQ to the tracing and would like some thoughts from anyone who may have had similar experiences that they could share.
We have tried to find some stuff online but can't seem to find an interceptor we could add to our rabbit implementation. Can you recommend anything?
Thanks in advance.
The best way to ask for a feature is using github issues.
To add a new transport such as RabbitMQ, you'd have to affect Brave (reporter) and Zipkin (collector)

How to add distributed tracing to websockets properly?
As each websocket connection is long lived, a lot of messages ends up getting traced under one activity. Is there any way to split that? (See below link for reference)
Looks like there is an issue written on .netcore github related to this but while it is getting fixed we want to have an interim fix. Any suggestions on how to handle this?
I am using Ehcache in my application. I need to monitor cache statistics using JMX. Ehcache provides an api net.sf.ehcache.management for the same.
Please let me know, how to proceed further?
Documentation on this topic can be found here, it should give you insights on what you need to do.
I've been using RabbitMQ in a few setups now, and I can't shake the feeling that there must be something that's more easily set up. Despite it's conveniences it's hard to justify MQ for a solution that only processes a couple of thousand messages a day, simply because maintaining RabbitMQ is so much work.
Does anyone know an AMQP implementation with a simple installation and maintenance process?
For those who don't know it, RabbitMQ is an AMQP implementation written in Erlang. It is supposed to be very stable, but that is only really the case if you know enough about Erlang to avoid its problems. Whether it's memory limits or changes in the hostname, there is always a need to get deeper into it.
http://www.zeromq.org/ might be what you are looking for.
If you are on Windows you might use MSMQ
EDIT: I guess I missed the AMQP part of the question.
ActiveMQ seems to be good alternative, I was using RabbitMQ to set up "cluster" over WAN, which is not supported by RabbitMQ cluster, since it requires all machines within same location.
It seems ActiveMQ is better than RabbitMQ, in the sense that it is easy to set up and maintenance, for "cluster"
Apache Qpid is another open source AMQP broker: http://qpid.apache.org/
Disclaimer: I haven't used it myself so I can't tell you how it compares to RabbitMQ.
I have tried and tested the JMX API and it is pretty simple to use and provides a vast number of statistics required for monitoring ActiveMQ.
But the problem is, i dont want to monitor my ActiveMQ remotely and also i dont want to use another API.To be more precise, i want to use the JMS API itself to get statistics related to various destinations and the broker itself.
Advisory messages seem to be an alternative but they provide limited Amount of Administrative Messages to monitor.
Any input is highly appreciated...
There is no built-in support for this. But you can implement a JMS topic which publishes the monitoring data every few seconds. Make the connection non-persistent so that it doesn't pile up when there are no listeners or when they loose connection.
Now you can write a client that connects to this topic and it will receive updates.
AMQ-2379 resulted in a broker plugin for grabbing statistics from destinations by sending a simple JMS message. Check out the docs that show how to use it here:
http://activemq.apache.org/statisticsplugin.html
The statistics plugin is available in the 5.3 release.
You can checkout this http://issues.apache.org/activemq/browse/AMQ-2379, it will be avaiable in upcoming 5.3.0 release
There's a blog post queued up to go on http://issues.apache.org/activemq/browse/AMQ-2379 - will post it in a couple of days or so
I'm experiencing an issue with ActiveMQ and would like to trace/view all ActiveMQ activity. The only log file I can find is one associated with persistent data (if this is turned on). Are there any other log files I view or generate to tell me what's happening under the hood of ActiveMQ and why my consumers aren't consuming messages? Any other suggestions?
Thanks in advance!
activemq has a jmx interface that you can connect to.
this gives us access to consumer counts messages queued dequeue and all sorts of data on memory usage etc.
http://activemq.apache.org/jmx.html
Has all the details to get you started.
I find it excellent in finding out whats going on with activemq.
A quick firing up of jconsole and you will be well on your way to finding out what is going on.

Agreed. Also you can add the logging interceptor which helps.
Finally for browsing messages, moving them, creating/deleting queues and sending message I highly recommend the new web console for ActiveMQ, Camel and many other plugins: hawtio
Try HawtIO. Assuming you are not using Active MQ 5.9 you can add this feature to your broker. It is a much better web console and a good JMX monitoring utility as well.
