Spring Integration - Monitoring
|
|
================================================================================
|
|
|
|
This application demonstrates managing and monitoring Spring Integration Applications.
|
|
|
|
It is based on the STS 'Spring Integration Project (war)' template project, available using
|
|
|
|
New... | Spring Template Project
|
|
|
|
It was used in the **Managing and Monitoring Spring Integration** webinar available on the [SpringSource Developer YouTube Channel][].
|
|
|
|
If you wish to see the changes made during the webinar, please use the following git command:
|
|
|
|
git log -p <The commit titled 'Webinar End State'>
|
|
|
|
|
|
To run the sample, in STS, use:
|
|
|
|
Run As... | Run on Server
|
|
|
|
and then use [VisualVM][]/JConsole to explore the [MBeans][].
|
|
|
|
The twitter search results can be examined at `http://localhost:8080/monitoring`.
|
|
|
|
## 2.2 Updates:
|
|
|
|
The application context now includes an example of <int-jmx:notification-publishing-channel-adapter/>, to which the tweets are published. You can navigate to the MBean - **spring.application:type=TweetPublisher,name=tweeter**, click the _Notifications_ tab and then subscribe. You will then see the notifications.
|
|
|
|
An additional class _NotificationListener_ is now included. It demonstrates the use of <int-jmx:notification-listening-channel-adapter> and <int-jmx:attribute-polling-channel-adapter>.
|
|
|
|
Also, it shows how to use an <int-jmx:operation-invoking-channel-adapter> to stop/start the
|
|
_dummyAdapter_ in the web application.
|
|
|
|
These adapters use a client connector to connect to the Twitter search web application to catch notifications published by it, polls the _sendCount_ attribute of the _twitterChannel_. and invokes operations on the _dummyAdapter_.
|
|
|
|
You will need to update the credentials on the _clientConnector_ in _remote-monitor-context.xml_ to match your environment. If you are using STS, you can find the credentials in _Servers | [server] | jmxremote.password_. You can then run the _NotificationListener_'s main method.
|
|
|
|
You should observe log output of the notifications as well as polling the channel's _sendCount_. Simply use the console to enter 'n' to stop and 'y' to start the adapter.
|
|
|
|
These changes show how you can create a sophisticated monitoring application using Spring Integration - it is important to understand that the application being monitored doesn't have to be a Spring or Spring Integration application - any application that exports MBeans can be monitored in this way.
