A free program for Android, by VMware Inc..

VMware vSAN Live is the new way to monitor your hyperconverged infrastructure environments. The app allows you to view all the details of your vSAN environments from a mobile device, including the status of the cluster. 

It provides you with the ability to connect to a specific vSAN resource, or a cluster, and view the status of the resource in more detail than ever before.  You can also change vCenter Servers, do health checks, and track performance for a streamlined monitoring experience. VMware vSAN Live is compatible with Android devices with Android 4.1 and newer.
