I have virtual Microsoft Windows 2012 r2 clustered installed SQL server 2012 (High Availability) monitoring by Opmanager.

Issue

Opmanager shows only one of the server online and second server status shows as critical while both of them are online and running

If I restart offline server status change on op manager first server goes offline and second server status updates from critical to online

for some reason opmanager is detecting only one server as an active server
