OpManager Plus is technically same as that of OpManager but follows a different licensing model. It packs all the add-ons with the base OpManager product license, at a discounted price.
Eg.: OpManager Plus 50 pack includes license for 50 devices monitoring, 15 interfaces NFA add-on, 15 devices NCM add-on, 1 Firewall add-on, 250 IPs and 250 switch ports add-on.
"OpManager Plus license options depend on the number of devices to be monitored. The license is inclusive of all the interfaces, nodes or sensors in the device. A device can have any number of interfaces, elements or sensors, unlike our competitors."
