You can use Symantec Cluster Server (VCS) or another Storage Foundation and High Availability (SFHA) Solutions product such as Storage Foundation Cluster File System High Availability (SFCFSHA) to monitor the health of the applications, as well as provide clustering and failover capabilities. However, you may not need the full feature set of VCS, SFHA, or SFCFSHA simply to monitor an application in a virtual machine. In a virtual environment, the size and resource requirements for an application are a serious consideration.

Symantec provides a lightweight, simple, application availability solution for virtualized workloads that combines seamlessly with clustering and disaster recovery solutions from Symantec and other vendors. You can use Symantec ApplicationHA. Symantec ApplicationHA provides an easy GUI- and wizard-based method for installing and configuring Symantec High Availability products and administering application monitoring on virtual machines.

For lightweight, easy-to-use application monitoring capability, use Symantec ApplicationHA in the ESXi guest.
