Introduction:

The DocOps site describes the necessary steps for setting up Load Balancing in an installation of CA Service Catalog 14.1 here:

https://docops.ca.com/ca-service-management/14-1/en/implementing/implementing-ca-service-management-14-1/step-4-install-or-upgrade/implementing-ca-service-catalog/step-3-perform-ca-service-catalog-post-installation-tasks/optional-implement-clustering/step-4-set-up-load-balancing

However, as well as testing the failover using the method described on that page, you may wish to confirm that both nodes are being used when all are up and running.

Question:

If all nodes of a CA Service Catalog 14.1 load balancing cluster are running, how can I see that sessions are being created on each?

Answer:

The simplest method to see that a Service Catalog node is serving pages to the users is to look in the tomcat log. This can be found at

USM_HOME\logs\view\tomcat_view.log

This log shows the pages being served by Tomcat, under the default logging level. For instance, here is an example of my user being successfully sent the Dashboard page after logging in:

"GET /usm/wpf?Node=icguinode.portalgetdashboard HTTP/1.1" 200 4905

Using this method, you can see if each node is actively used, rather than the load balancer only sending users to one.
