How to use EventSubscription and EventNotification with iControl.jar

Your code for the subscription creation looks good. When events occur, they will be sent to the URL you specify in the subscription information. Have you tested your endpoint to ensure it can take a webservice call? I've included in the SDK a perl sample client (EventNotificationClient.pl) that you can use on your BIG-IP (if you don't have the perl environment on a test machine) to send a sample message to an endpoint to test that it's configured properly to receive web service calls.

 

 

I honestly haven't done much with the java listening piece of things. If you have verified that the your endpoint works, you might want to run a tcpdump to try to see if any traffic is getting transmitted.

 

 

If all else fails, you can run the event daemon on the BIG-IP in debug mode

 

 

$ bigstart shutdown eventd

 

$ /bin/eventd -d -f -o

 

 

 

This will run the event daemon in console mode with all debug information printed to the console. This should shed some light as to what is going on.

 

 

To get the event daemon back in daemon mode break out of the user mode running and type the following

 

 

$ bigstart startup eventd

Hi,joe

 

I still have a problem,how to simulate events occurred? I shall test my endpoint to ensure it can take a webservice call.

Before I run the event daemon on the BIG-IP in debug mode

 

I have deployed webservice on one machine"10.0.1.34",then

 

I run my subscription on another machine"10.0.1.33",and return the subscriptionID"A8A986D9-1974-6756-6247-0150A07139C2"

 

then I run the event daemon on the BIG-IP in debug mode

 

 

Some logs are as follows:

for what reason there is a SOAPException:SOAPException on notification attempt: Timed out waiting for socket read.

 

 

another question: The value of min_events_per_timeslice should i set what?

SOrry,subscriptionID"A8A986D9-1974-6756-6247-0150A07139C2" should be "E263EDF9-1974-ABEA-9046-B0D7A2B7442B

 

"

 

OK,The problem has been solved,many thanks

Glad to hear it! Sorry I didn't get back to you sooner, I've been out of town at a Conference this week and I haven't had much time to sit down and look at posts.
