Xangati for ESX (ESX 4.x)
Xangati for ESX is a virtual appliance that provides VM-to-Anything visibility for VMware environments. Xangati delivers visibility into any VM's communications activity (VM-to-VM, VM-to-app, VM-to-storage, VM-to-VDI client, etc.). It installs in less than 30 minutes and immediately offers to-the-second visibility into what is happening within your ESX: how its VMs are interacting with each other and the rest of the virtual/physical infrastructure. Powerful drill-down and DVR recording features enable one to solve lingering performance issues as well as to ad hoc troubleshoot problems.
