Managing System KPIs and Events in a separate Rule engine

Hello Tech community,

Is there any client where system related KPIs, Events and Threshold rules been defined and managed in a separate place. This could be done in a separate rule engine like Blaze advisor. At the moment all the system related KPIs/Events are defined and maintained on MWS page itself, which has got lot of other stuff and make the life more complex. If we come up with this, it can be used to maintain business related rules/KPIs as well.

Appreciate any pointer to this.
