This article describes the configuration differences on a NetScaler for SLB configuration in Exchange 2013 compared to SLB configuration in Exchange 2010.

Instructions

Where previous documents used a single monitor, the new guide says to use a monitor for each back end virtual directory, which results in 8 monitors per service group. 

A single namespace is deployed for all HTTP protocol clients (mail.contoso.com). The load balancer is configured to maintain session affinity (Layer7), meaning SSL termination occurs and the load balancer knows the target URL.

The load balancer is also configured to check the health of the target CAS in the load balancing pool; in this case, the health probe is configured on each virtual
directory.

First thing is we need to create monitor for every location on Exchange:
add lb mon monitor-exchange-owa HTTP-ECV -interval 30 -secure YES -send "GET /owa/healthcheck.htm" -recv "200 OK"
add lb mon monitor-exchange-ecp HTTP-ECV -interval 30 -secure YES -send "GET /ecp/healthcheck.htm" -recv "200 OK"
add lb mon monitor-exchange-ews HTTP-ECV -interval 30 -secure YES -send "GET /ews/healthcheck.htm" -recv "200 OK"
add lb mon monitor-exchange-oab HTTP-ECV -interval 30 -secure YES -send "GET /oab/healthcheck.htm" -recv "200 OK"
add lb mon monitor-exchange-rpc HTTP-ECV -interval 30 -secure YES -send "GET /rpc/healthcheck.htm" -recv "200 OK"
add lb mon monitor-exchange-eas HTTP-ECV -interval 30 -secure YES -send "GET /microsoft-server-activesync/healthcheck.htm" -recv "200 OK"
add lb mon monitor-exchange-aut HTTP-ECV -interval 30 -secure YES -send "GET /autodiscover/healthcheck.htm" -recv "200 OK"

Next we need to bind all monitors to all services of exchange servers:
bind lb monitor monitor-exchange-owa servicegroup-exchange-https
bind lb monitor monitor-exchange-ecp servicegroup-exchange-https
bind lb monitor monitor-exchange-ews servicegroup-exchange-https
bind lb monitor monitor-exchange-oab servicegroup-exchange-https
bind lb monitor monitor-exchange-rpc servicegroup-exchange-https
bind lb monitor monitor-exchange-eas servicegroup-exchange-https
bind lb monitor monitor-exchange-aut servicegroup-exchange-https
