Questions # 7:

True or False? SteelHead SaaS can provide Netflow and SteelFlow to other Riverbed products to monitor and troubleshoot SaaS performance issues.

Options:

True

False

Answer

Explanation

NetFlow is supported. To enable NetFlow on the Riverbed Steelhead appliance running RiOS v5.5.1 or RiOS v5.5.3, navigate to the Configure, Networking, NetFlow page and set the configuration.

All SteelHead appliances can send SteelFlow data to SteelCentral NetProfiler (free of charge): SteelFlow is a Riverbed-specific version of NetFlow that provides visibility into SteelHead QoS, response time, WAN optimization reporting, application visibility, and so on

Late last year [2014] Riverbed enabled deep integration between SteelHead and SteelCentral AppResponse. AppResponse lets you monitor the end-user experience for SteelHead-optimized web and SaaS applications.
