Thanks for the response.
My next question is, if we upgrade to Essentials Plus, will the VM application monitoring work regardless of the fact that we won't satisfy other requirements for HA operation, i.e., our setup is only two ESXi hosts with each using local storage.
VM Monitoring and Application Monitoring doesn't need shared storage. It will work as follows:
1. has the ability to restart the monitored service
2. has the ability to restart an operating system
Now monitoring the service isn't necessarily easy or a "1 click" operation. I think there are easier methods for this this, most are included in modern operating systems, which i probably would recommend looking at before using Application Monitoring.
Anyway, if you do want to use Application Monitoring, there's a chapter in my book on this topic, feel free to download it here (free download!) >> Rubrik | eBook: Clustering Deep Dive
