Dynatrace: what is the meaning of srv in dtCookie Cookie set by UEM

Question

I have a website where UEM is activated.

It adds this cookie:

Set-Cookie: dtCookie==3=srv=6=sn=XXXXXXXXXXXXXXXXXXXXXX=perc=100000=ol=0=mul=1; Path=/; Domain=.foo.com

I would like to know the meaning of srv. Is it a number for server or something else ?

I didn't find in documentation any information on it.

Answer 1

It's not related to the number of servers as I have seen the values higher than the number of servers. Something internal to DynaTrace and as you correctly said there is no documentation for this.

Answer 2

It's the ID of the cluster server node that is supposed to correlate that user session.

It's undocumented, since it's an implementation detail.
