Not seeing application functions in purepath inside WCF
Hi,
We're evaluating DT 5.0 on an application which is utilizing WCF services at the end (running under windows services). I can see the complete purepath until the call to this WCF, but I am missing information inside the WCF itself, when it invokes (using reflection) methods inside it.
Looking at the sensor group I can see that autosensors were deployed to the application code itself, however, no data is seen.
Looking at the transaction flow, it also seems like it does not recognize the invoked methods as part of the agent group and draws them as a domainless cube, not being monitored (see attached image).
any ideas ?

here is the purepath for example. you'll see calls from the host_2 agent which are missing.
hi Gil,
which calls are you missing exactly? the ones from
- TheLotter.Host__2@tlapp30:36716 or also the ones from
- TheLotter.com[www.theLotter.com][1]@tlweb31:3684
in this PurePath there's a lot of WCF client calls (~50) to http://tlapp30:887X/ComponentService (where X is 0-5).
however, only 2 of them have a server-side and those are the ones to http://tlapp30:8875/ComponentService (TheLotter.ESB_3@tlapp30:26400 and then TheLotter.Host_2@tlapp30:36716).
so i'm still wondering if there are .NET agents in all of those processes? can you see them in the agent overview?
and if so, do you get separate PurePaths for them? maybe if you turn the .NET WCF sensor to active and start PurePath?

Christian,
there are agents on all of the ESB's and you're right. I'm missing ones from both Host_2 and the web. All of the 8870-4 are not seen even though the agent says it has placed sensors on appropriate methods.
hi Gil,
so based on your screenshot these WCF calls are shown as 'external calls' which means that there is no agent injected on the receiving end of these calls.
am i right?
so that would explain your questions.
for us to get more insight it would also help to attach a PurePath here (as a session).
best,
Christian
Christian,
This is what I'm afraid of indeed. The "missing link" in the purepath ends at "invoke". talking to the developers it is raised in the same process (windows service). I will try and get one purepath to attach. since this is a live system, we can't restart the service all the time so if you think of any other tests we should do at the same time, pleae let me know.
Gil.
