If you have restarted all of your arservers, without the right settings,
all of your mid-tiers might be still connecting to just the first ARServer
you started up. one way to trigger a rebalance is to click on 'Balance Now'
from the mid-tier config pages.
May I ask how are you determining an even
Thank you all for your valuable contributions!
We asked to remove the persistence on the LB and we no see an even distribution
of users on all AR Server.

Jason,
You are correct, Jetty running on port 8008, or whatever port they are on
certainly needs it's own LB depending on the need of the client in place.
If HA is needed, LB makes sense. Regardless of if you are talking about
Remedy Restful services or CMDB Restful services...depending on the HA
But you can see in the screenshot that the maximum for each is in the 30's,
so from that it seems to me that the LB is able to recognize unique
individuals coming across and not treating the Mid-Tier server as a whole
as a single userbut I do agree with you that there is 0 reason to have

Hi,
So if you have say 4 mid-tiers and 4 remedy-servers and 100 users.
The first load balancer will dirstribute the 100 users to something like 25 per
mid-tier server.
The load balancer between mid-tiers and the remedy-servers will see only 4
"users", which is the 4 mid-tiers. It is not inposs
Node 3 seems to be used 50% more than node 1, but agreed that everything

You still haven't identified what sort of monitor is in use, and if node 1
goes down/offline at any point...I'll give you a scenario
all 3 getting normal load, but node 1 goes offline, eit
I'll also use this thread as an opportunity for a new discussion related to
load balancing.
Is anybody aware of any docs that pertain to load balancing Jetty on AR
Server? The REST API has been hosed here for a few years but that wasn't
user-facing (but should be able to setup redundancy). The new

get an equal amount of requests.

Perhaps a problem with apptier load balancing?

I reviewed that info before posting here but don’t really see room for change.

There isn't much can be done in mid tier.this is purely LB team need to

connections are going to one server in reality with the help of logs.. we
had strange problem recently that on 2 AR servers we used to see same set
of user
I've always preferred to use least connections personally, but from what
I've read of the docs they recommend round robinbut round robin doesn't

literally go 1, 2, 3, 1, 2, 3 for new connections, and as you discussed,

Hey LJ and thank you for the prompt reply.
Talked to them already. We’re using round robin. I’m not an expert on LB but my
understanding was that we would have about an equal amount of users on all AR
Servers using it.
The guy explained that once you connect there is a time out of 180 seconds.
Thomas,
You'll need to work with the LB team to identify what distribution method
they are usingcommon options are 'round robin' in which it just simply
points everything at each server in turn, 'least connections' where it
tries to analyze how many are 'currently' connected to each node and se
