Installing Activity Monitors for Access Zones of the Same Cluster

Due to limitations of the CEPA architecture, all activity monitor services, monitoring access zones of the same cluster, must be installed on the same File Access Manager Server.

The File Access Manager Isilon Activity Monitor is a multi-instance service, i.e. a single service serves multiple instances of the activity monitor, e.g., for the different access zones. As a result, only a single service will be created (and appear in the Windows Services list), however, this single service will create activity monitors instances for all the Isilon access zones it is configured to monitor.

There is no limitation to the number of clusters that can be monitor by a single File Access Manager service. Although all monitors for access zones of the same cluster must reside on the same File Access Manager server, activity monitors for other clusters and their access zones can also be installed on the same File Access Manager server, provided that sufficient resources are allocated for that machine.

We recommend that instances be added gradually, and resources be allocated appropriately to accommodate for the increase in activity volume, as the scope of the monitored environment grows, and more activity monitors are added to the server.
