EUM BT correlation

[gaurav.sharma]

HI  All, 

I have one question . Normally we see BT correlation b/w browser activity and its respective JVM . 

But im my case if i have passthrough layer of webserver  i.e.  browser --> webserver --> JVM . do we see the BT  correlation here ? please advise !!

Hi Gaurav

First Question is, do you have all 3 layers instrumented?

1. Front End With Adrum End User Monitoring

2. WebServer , with AppAgent?

3. JVM App server with AppAgent?

If you only have 1 & 3, unless there is something within the webserver that removes the correlation headers, what will happen is that you will see a correlation in e.g the snapshot that shows the time from Browser > JVM, even though there is a WebServer in-between.

If you have all 3 layers instrumented, you will still see the correlation between all 3. You will see the Browser correlation to the backend webserver BT, which then will show a downstream call to the JVM(App Server) BT

Ciao

HI Mario ,

First of all thanks for reply .

FYI ... Instrumentation is available for front end and JVM . Weblayer is not instrumented yet. But as you mentioned we can correlation b/w frontend and JVM through snapshot  correct ?

That is correct,

As I mentioned, if for some reason the correlation does not work, some WebServers do not allow other headers etc. Or will block them for security, which will break the correlation. Will just have to then have the customer check and allow it.
