Maybe we could consider to build a common notfication layer for sending
this kind alerts across JMX and other management Agent.

The monitoring of things like thread pools, memory or exceptions can be easily
built on top of JMX layer. I would rather see a Camel events published to snmp
than another DSL extension in default camel namespace.

Hi Johan,
that sounds great.
The only thing we should take care of here is to not couple the alerting too
much too the things we want to monitor. So I propose to only generate internal
events in the
camel core. Like an event when a thread pool is accessed or a exception is
caused. The alerting could then be in its own module and analyze the low level
events and create new events like
you described. The current event system can be a quite good base for these
efforts.
Btw. when you work on the even system you could check if it can be made less
intrusive. Currently the eventing couples where the events are generated to
much to the eventing. I also plan to improve some of this for camel 3.

Thanks for you feedback!
Chistian:
Exacly, general idea can present the following hypothetical configuration:
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring";>
<alerts>
<threadPoolAlert id="tpa" profile="fooProfile" severity="major"
threshold="70%" />
<lowMemoryAlert id="lma" pool="PermGen" severity="critical"
threshold="80%" />
<exceptionAlert id="xa" type="com.foo.MyException"
severity="critical" />
</alerts>
<threadPoolProfile id="fooProfile" poolSize="20" maxPoolSize="50"
maxQueueSize="-1"/>
<route>
<from uri="alert?id=tpa"/>
<to uri="smtp://ad...@mymailserver.com?password=secret"/>
</route>
</camelContext>
Alert will generate an event and specified route can receive this event.
Christain, do you mean something like that?
Johan,
thanks for thanks for the support.
Michal
