For a long time, I was asking the engineering to include PING functionality in vRops, luckily they heard me, better later than never. So I made this dashboard to help you to understand availability based on ICMP protocol (PING), just follow the instructions below:
1) Enable Ping Management Pack (You can see the details here (Thanks Brock).
2) Import the Alert and the Symptoms definitions download from here and here
3) Import the Dashboard from here (Or attached in this post).
4) To configure the alert part of the dashboard, see the image below
