Orion Network Performance Monitor (NPM) 授權數如何計算？

取 Interfaces、Nodes、Volumes 這三種監控標的當中的最大者來計算，例如：監控的 Node 有 2 個、Interface 有 10 個、Volume 有 5 個，則物件數是算 10 個，並不會有重複計算之疑慮，請放心！下圖是試算範例：



Licensing Orion Network Performance Monitor
Orion can collect data and detailed information from any of your version 3 or
earlier SNMP-enabled devices, including routers, switches, firewalls, and
servers. You license Orion by the largest number of the three following licensed
objects:

Interfaces
Interfaces include switch ports, physical interfaces, virtual interfaces, subinterfaces,
VLANs, and any other single point of network traffic.

Nodes
Nodes include entire devices, for example, routers, switches, servers, access
points, and modems.

Volumes
Volumes are equivalent to the logical drives that you monitor.(Volumes等同於你監控的邏輯硬碟數量。)

The following list provides the different types of Orion Network Performance
Monitor licenses that are available:
• Up to 100 objects (SL100)
• Up to 250 objects (SL250)
• Up to 500 objects (SL500)
• Up to 2000 objects (SL2000)
• Unlimited objects (SLX)
