So esxcfg-info is not a command that is available from vMA, because the information that it gather is not all available through the vSphere SDK for Perl/VI Perl Toolkit. You can get a subset of that information which is exposed through the API, and it depends on what you're looking for.

Here are two health scripts I wrote for both ESX(i) 3.5 and vSphere ESX(i) 4.0 which gives you an idea of some of the details available through the API:
VMware Health Check Report v0.9.4
VMware vSphere Health Check Report v1.2

You can access esxcfg-info by SSHing into the classic ESX hosts that have the traditional Service Console from vMA, but you won't have that with ESXi which does not have the Service Console. For a list of commands that are available with the vCLI, you'll want to take a look at the documentation: http://www.vmware.com/support/developer/vcli/
