7 HP OneView Event Manager Service
HP OneView Event Manager Service (EMS) provides monitoring data to indicate any information
change to the monitored devices. It consumes state change messages from HP OneView appliances
by establishing a SCMB exchange. As soon as it receives state change messages from the appliance,
it formulates the message and generates NT events for the SCOM rule to pick.
NOTE: The HP OneView Event Manager feature needs to be installed in all the management
servers under the HP Resource Pool for HP OneView Management Pack.
