3.2.3 Effects when PFM - Manager stops
PFM - Manager affects the entire Performance Management system when it stops.
PFM - Manager centrally manages the agent information of the PFM - RM for Microsoft SQL Server agents that are running on all nodes. It also controls notification of alarm events in the event a threshold value is exceeded during performance monitoring by PFM - RM for Microsoft SQL Server as well as execution of actions based on alarm events. Accordingly, when PFM - Manager stops, the entire Performance Management system is affected, as described in Table 3-1.
