I'm monitoring network devices, HP Procurve switches mostly, using SCOM 2012.
In Network Summary Dashboard I see top 10 of nodes with slowest response time, but the latency presented here doesn't match real life situation.
Whenever I ping network nodes from within the management VLAN (and from outside for that matter) I'm nowhere near the numbers presented in the dashboard. (Ping ~1-3 ms, Dashboard shows 17-20 ms)

Also, Nodes with Highest CPU Usage is empty. Do I need to enable a monitor for this view to be populated?
Thanks!
