Andrew,



Yes.

Well, actually it depends on how the "alphabetize" process was programmed by 
Citrix...

(You know the whole 'left-to-right' issue w/ 1, 10, & 01 in numbering.)



In the whole 4.5 farm: No, about 1/3 of the way down the list of 46 total.



In this set of servers w/ published-app:  Yes, #3 in the list of 20.

I seem to remember that our Support asked that question once, but it never went 
any farther...





Any ideas on where to track down this train of thought?



Thanks,

Troy

Is the servername higher up the alphabet?

Subject: [THIN] Citrix Load Evaluator / Total Sessions per Server &

Application



Hey all,



We've had a small issue for the past year, and I can't seem to find an

answer about it.



We started a new 4.5 farm this time last year and have an application that

is published & load-managed across 20 servers.



There is a custom load-evaluator is built on these 4 "Assigned Rules":

Application User Load, Load Throttling, Memory Usage, Server User Load.



Overall, this load-evaluator appears to be working well for our userload;

per server and per application.



Except... One server seems to always have about 10-20% more total sessions

then the other 19 servers.



Over thousands of session - the 19 servers will all be within a range of 100

or so total sessions, but this one server will be always at the top of the

list for total sessions by several hundred more sessions for any time

period.



Theoretically - all of these are equal.



At anytime I run a "qfarm /app" (during average workday) - all of my servers

are in the 4500-6000 load range.

In the "Presentation Console" everything is running against this

load-evaluator.

Also, We have Citrix Edgesight collecting data, that looks normal other than

the total session count.

My performance statistics appear fairly normal at anytime we take a look.

The application is installed identically across the 20 servers.



Anyone have any ideas?



Thanks,

Troy
