EventNotification Web Service in SDK not working

In an attempt to get event notification to work correctly, I placed a copy of the SDK's example EventNotification web service on a IIS server. We only use Visual Studio 2005 here so I did convert the project to ASP.NET 2.0 before posting it. I then created a subscription pointed to the URL of the new web service and listening for EVENTTYPE_POOL_MEMBER events.

 

 

However, when I changed the status of one of the pool members, it failed to invoke the web service properly. I know this because it is designed to send an email message when it is invoked. Invoking the web service from within a Windows app works fine. Looking in the /var/log/LTM file on the BIG-IP I found the following error message:

 

 

Notification attempt to consumer id 73E66D18-1974-F119-9455-5E7A13B5C5A4 FAILED with error SOAP Fault: Server

 

did not recognize the value of HTTP Header SOAPAction: urn:iControl:Management/EventNotificationevents_occurred..

 

 

What should I look into? Is my web service constructed incorrectly?

    There must be something that has changed since VS.Net 2003. Try modifying the Action attribute on the events_occurred method call in the EventNotification.asmx.cs file from

    [WebMethod]
[System.Web.Services.Protocols.SoapRpcMethodAttribute(
"urn:iControl:Management/EventNotification",
RequestNamespace="urn:iControl:Management/EventNotification",
ResponseNamespace="urn:iControl:Management/EventNotification",
Action="urn:iControl:Management/EventNotification")]
public override void
events_occurred
(
ManagementEventNotificationEventSource event_source,
string subscription_id,
ManagementEventNotificationEventData[] event_data_list,
CommonTimeStamp time_stamp
)

    to

    [WebMethod]
[System.Web.Services.Protocols.SoapRpcMethodAttribute(
"urn:iControl:Management/EventNotification",
RequestNamespace="urn:iControl:Management/EventNotification",
ResponseNamespace="urn:iControl:Management/EventNotification",
Action="urn:iControl:Management/EventNotificationevents_occurred")]
public override void
events_occurred
(
ManagementEventNotificationEventSource event_source,
string subscription_id,
ManagementEventNotificationEventData[] event_data_list,
CommonTimeStamp time_stamp
)

    And see if that clears things up. If so, I'll get the fix included in the next rev of the SDK.

    Actually it looks like the SoapRpcMethodAttribute tag did not have an Action attribute at all. I have added your new version and I am testing now. I will let you know how it goes.

     

     

    Thanks :D
