About a month ago, April 2014, VMware released App HA version 1.1. App HA is a newer product that is managed through the vSphere Web Client. It essentially uses Hyperic to monitor important services on your VMs. If the service stops for some reason it will automatically restart that service. You can configure trigger notifications to let you know if a service has stopped and if the service cannot be restarted. App HA is available in any recent version of vSphere (5.1U2 and above). It does require deploying a Hyperic server, but doesn not require you to purchase Hyperic.
