Use of Solution:
I began using ARX in 2008. I use it frequently as an APM analytic tool.
I've found these appliances to be very stable
Although the Director provides some centralized management and RPM Dashboards provides some degree of integration, each appliance stands alone in collection and analytical ability. The appliances come in rather large sizes, but if you have a large enterprise and you're looking to bring data feeds in from several locations, it will likely have to be served on several appliances.
Disclosure: My company has a business relationship with this vendor other than being a customer: We provide professional services replying and using the analytic functions for Riverbed customers. We are also a partner.
