AppInsight for Exchange and component-based licensing
Per the SAM licensing model, if using AppInsight for Exchange with a component-based license, 50 component monitors count against the licensed number of component monitors per Exchange server.
AppInsight applications provide tremendous value while consuming a fixed number component monitor licenses. However, they cannot be partially unlicensed because the way they collect data differs significantly from traditional application monitor templates. You can disable some components within AppInsight applications but they will not reclaim component monitor licenses because AppInsight applications typically monitor more than 50 components.
For example, if you have an active license for 1,500 component monitors and use AppInsight for Exchange to monitor 88 mailboxes over 10 Exchange servers, 500 component monitors count against your total license. The amount of licenses used is strictly per server instance.
(50 component monitors X 10 Exchange Servers = 500 component monitors used.)
This leaves 1,000 component monitors available for use elsewhere.
(1,500 component monitors – 500 component monitors used for AppInsight for Exchange = 1,000 component monitors remaining).
If you choose not to use this AppInsight, you are not penalized any number of component monitors.
The example below illustrates a situation where you have 40 available component monitors available, but surpassed your allowed number of 300 monitors by 60. AppInsight applications are licensed as 50 monitors per application and cannot be partially licensed, as described above. Although you may be able to disable some components in an AppInsight application, they will not reclaim component monitor licenses because AppInsight applications typically monitor far greater than 50 components.
