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.

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.

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.

  • Thanks for your answer. I upvoted, but before accepting , I need a clarification, I am supposed to have 3 servers but srv ranges from 1 to 6 ? Is this regular ? Can you explain ? Thanks – Yution Lio Jan 29 '20 at 16:37
  • No, these ID's are not gapless counts. So, seeing a 6 in a 3 server setup is totally fine. Sometimes these ID's reorganize, e.g. when server nodes restart during rolling updated. – chrisn Feb 10 '20 at 20:17
