I've got a streaming UDP application that generates a stream of messages in a legacy format. These messages are generated in an un-solicited fashion (that is, it is not request/response).
I'd like to build a custom message mediator to take these messages into an enterprise network.
Can someone please point me to one or more samples in the WSO2 ESB portfolio that are a good starting point for building a custom mediator?
Any other samples, or examples, to serve as a starting point for a WSO2 ESB novice that needs to develop his first custom mediator would be appreciated.
You can refer these links.

Recently I installed Rabbit MQ in Centos8 for my company. We also using Splunk Enterprise so we wants to integrate our Rabbit MQ to Splunk and we wants to see, search, check our logs which is coming from Rabbit MQ to in Splunk . How can I do that I don't know. I google it but I didn't get info about it. May anybody help to me for this goal ? Thank you
The scripts at https://github.com/jerrykuch/rabbitmq-splunk are somewhat old, but should still be functional. It can leverage the HTTP API to pull in the relevant data. That page also lists the recommended files to monitor
Always check Splunkbase when looking for ingesting data types - often there exist apps and add-ons that will do what you're looking for
Here are two related to RabbiMQ:

I have some subscribers that they are listening to "mytopic"...I send message to them by browser UI just like attached image
but now I want to do this work in code environment
what should I do and whats that code and methods?
-----> attached image
Thanks
You should have mentioned what programming language you want to use. Every language may offer a different API and specification.
In case of using Java, you can simply program according to the JMS specification
https://docs.oracle.com/javaee/7/api/javax/jms/package-summary.html
Also, the Apache ActiveMQ installation comes with a few examples that you can use as a reference. E.g. see
examples/openwire/swissarmy/src/TopicPublisher.java
You should have a look at ActiveMQ Protocols - for example you can use the ActiveMQ REST API to POST messages to the topic or use JMS.
Then you can look at how to use these from a "client" (presumably your central server) perspective.
For REST from Java (say) you could look at this article

I see the following
EE-3141 When using a Throttling policy with throttling statics enabled, limit headers are swapped.
However, I can find no example of throttling policies within Mule ESB, but there is possibly a throttling policy within the Anypoint API Manager
Could someone please provide a link to how to use a Throttling policy within Mule ESB?
Thanks
To achieve correct Throttling behaviour you can follow below steps:
Configure a queue (for example, a persistent VM or a JMS queue to avoid message lost during the Mule server crash) after your inbound endpoint.
Configure scheduled delay, for example AMQ_SCHEDULED_DELAY in case of ActiveMQ, to a desired value. If the queue does not support scheduled delay, then we need to find our way to achieve the delay, probably using a Java component.
Finally, configure the outbound endpoint.
The Throttling module (which can be configured as throttler or rate limiter) comes out of the box with any Mule API Gateway distribution. Mule EE comes with a light weight version of it. If you are using Anypoint API Platform, then you don't need to pay attention to the internals of how it is being done: Simply apply/unapply the policy to your managed API and it will work like a charm.
Even i tried implementing the Throttling concept in mule flows. There is no exact way of implementation for this , but i was able get that nature into the flows using the receiver thread profiling at inbounds and dispatch threading profiles on outbound connectors.
Mule Healthcare Toolkit is a collection of features that facilitates integration with healthcare systems by providing the tools needed to easily create, read and transform HL7 version v2.x messages within Mule... Unfortunately, it is available only for Mule ESB Enterprise!!!
Is there a way to implement a complete messaging service based on HL7 using the Community version of Mule?
Best regards, Vi.
Apache Camel has HL7 components that you can use to create HL7 routes. You could possibly then route this to mule via a web service call or a JMS call being hosted by the Mule ESB for example.
Apache camel does not require a full ESB (it is not a ESB) so it could act as some sort of translator proxy.
Might not be your cup of tea though.
I realize this is an old thread, but it appears that the Mule Healthcare Toolkit uses the open source HAPI library for (at least some of) the HL7 v2 message support. You'd have examine it more closely, but I suspect one could create their own Mule components using HAPI.

We have more than 5 corporate applications running on different servers with technologies like spring, struts communication between these application is point to point. We are planning to migrate this to ESB using Mule.
I didnt quite understand how mule works i have few doubts,
Mule is running in a different server do i need to deploy all my 5 aplications into the mule server.
I have spring application delployed on a tomcat server how this application is going to receive messages through mule or what are the configuration changes i need to do in my server or mule server.
Any advice or tutorials.
You need not deploy all you 5 applications in the Mule Server.
You said that all your application are currently point to point (which means that all are talking/communicating now through http protocol), similarly you can also use mule's http endpoints to communicate with all the 5 applications.
I.e. the spring application talking to another spring application can be modified to Spring application talking to Mule and Mule in turn talking to another Spring application .
You must learn the basics from the Documentation
http://www.mulesoft.org/documentation/display/current/Mule+Fundamentals --> browse through the navigation on the lefthand side.
Mule is an integration tool. you no need to change any of your existing applications. All you need is to develop an mule application which can do the mediation/orchestration.
For connecting with your spring application you no need to change any configuration you need to use http:outbound connector inside your mule flow
Just go through http://www.mulesoft.org/documentation/display/current/HTTP+Transport+Reference
So mule is based on SOA principle, so your 5 corporate service need not to be their in a single system. so if you want to consume the service/functionality of any of your 5 application, expose those service as web service, cloud be soap or rest. And you can call those service inside your mule. so in this case you have to create only 5 connection and where ever required you can refer to those connection inside mule configuration file.
#saravanan shanmugavel you need to use Mule ESB to orchestrate the communication between these application...ESB came into the picture to remove your point to point communication...you can create a proxy service for each of your service and one flow which will orchestrate communication between all...
All you need to do is change the application that is configurable according to mule server.
Please refer below link that will be helpful for understanding of mule that helps you better orchestrate communication between all.
