Difference between Server time in User Experience and Analytics (AJAX)

[CommunityUser]

Hi,

We are using AppDynamics Version 4.4.1.4, build 188.

Trying to extract some performance data from Analytics. But the value for "Server time" a.k.a "Application Server time" is difference from the value seen in User Experience.

The value in user experence seems to be correct, but in Analytics it is a lot smaller.

End user response time, First byte time, AJAX response download time and AJAX Callback execution time matches between User experience and Analytics.

Why is there a difference for Server time between Analytics and User experience (even for the same request)?

What is server time in Analytics?

Hi Joakim,

Is this issue very regular and happening for all the requests or is it just random and sporadic? Generally this is seen because the Analytics data is coming from a different store (analytics indexes) than the EUM metric data store(eum database), so they will mostly be a bit different than the other but I would expect them to be close. But still in some cases these data store may have slightly different reportings because of one of the following reasons :

1. Controller not able to pull data from EUM for some period of time. (may be due to maintenance/network)
2. EUM processor not able to send data to Analytics. (may be due to maintenance/network)

Can you please get me a screenhsot of the difference in values you see in each screen for any specific request that you would have tracked. If possible also send me a HAR file for this request. Here are the steps how you can create a HAR file:  https://docs.appdynamics.com/display/PRO42/Create+a+HAR+file 

Thank You,
