Finding remote WebService endpoint value

Hi,


Any idea how to find what DownloadMetadata() is trying to retrieve?

Is there any way to get it visualized in Service Flow?



Thank you,

For investigation what the method is trying to do, you would have to dig into the code.


Based on your method hotspots it's clear that there is a network IO involved. I'm not sure how many stack-traces were included in this hotspot analysis - if the number is too low, it won't be much valuable for getting any conclusions. Typically such situations as you have are in cases where network latencies or retransmissions happen (more likely) or a high volume of data is transferred (less likely in this case).

To visualise it in the service flow, you would normally have to define a customer service. Since this is a NET system class, this is unfortunately not possible.

Closest visualisation I can think of would be the custom service metric that will measure the network time for those particular services and requests. But it will be calculated from the service itself. Not measuring just DownloadMetadata.

Thanks, Julius.


What I am trying to find out is the following:

I found have method hotspot for this particular problem reported and now how to get the endpoint location that is consuming the Network IO.

I am drilling down to DownloadMetadata() and I cannot figure out what is being called.


Any tips?

One approach I can think of would be to capture relevant transaction data using request attributes. Unfortunately, you define request attributes based on .NET method arguments only on non-system classes. So you have to define in your code and then based on the data try to figure out, what was called.


On the other side, since it's a HTTP request issued from the code, what other services or request to unmonitored hosts are called from this purepath or service? It will likely be one of those URLs.
