| tracing web service calls |
 Our three tier web application is "pausing" under test loading (IIS 6.0
(win2003) -> Web services (win2003) -> SQL server) . The CPU usage on
the W3WP.exe on both the web server and middle tier drops to zero for
about 5 seconds then springs back into life. Nothing in the NT event
logs. No SQL database blocking.
I suspect it is a particular web service call. With SQL server I can
start a "trace" and get a list of all SQL calls (and their
parameters) and how long they are taking - this allows me to track
down "slow" SQL code. I can't see any tool that allows me to do
this for web service calls? Surly there is some IIS plug in that will
allow me to monitor this traffic?

Thanks for the suggestion. The logs do not show me the actual web
service requests - something that should be easy to do as its all XML.
I think the IIS team needs to have a look at the SQL tools and get
something similar to their profiler. I beleive IBM have created such a
tool for their web service solutions.

Just dress your method with a [Trace( FileName="here">)] attribute and the request + response will be saved to the
file. This applies only to the Request or Response XML, not the HTTP
headers.

You could try developing a Web Service SoapExtension to log the SOAP
messages for the problem method(s).
