VMware vFabric Application Performance Manager sets a new standard for
how businesses will manage applications in the cloud. With a focus on
key indicators for application performance, such as throughput, latency,
hit rate and error rates, along with deep code level diagnostics, the
vFabric AppInsight dashboard provides IT and development teams with a
common perspective so they can work together to fix problems quickly.
Below are some examples of what AppInsight dashboard gives you. In short the AppInsight probes run on the ESXi hosts. The BCI (Byte code Instrumentation) agents gives you the code level monitoring required from your java middleware VM's so you can for example see the SQL executed for any page request so developers can easily debug code.

Note: This topology builds itself out thanks to the Application Probes running on the ESXi hosts.

Note: Here we can see how the BCI agent gives us the code instrumentation so you pin point where latency/errors are occurring in the actual java code.
