An event processor (EP) performs duties that were performed by the IBM® Control Center
Monitor engine before V6.1. With an
EP, you can manage and monitor multiple servers and process events from the monitored servers.
When multiple EPs are configured in a high availability environment, they are automatically or
manually assigned to monitor servers depending on the configurations. All events from a server are
processed by the same EP. The functions of all EPs are the same except for the controller EP. The
controller EP is responsible for monitoring EPs and performing functions that cannot be delegated to
other EPs. When an EP is down, the servers that are monitored by the EP are temporarily distributed
to other EPs in the cluster according to the failover and load balancing policies configured for the
If you have the administrator permission of IBM Control Center
, you can rebalance your
server assignments among EPs in the same cluster, including EPs that are not running. To do so, go
to in the web console and click the rebalance button. When you click the button, your
servers are evenly distributed among all EPs in the cluster based on the number of servers, except
servers that are not allowed to reassign. This rebalance can take several minutes to complete and
will disrupt monitoring until completion.
Important: By default, Sterling Connect:Enterprise® for z/OS®, FTP z/OS, and WS_FTP
server types are pinned to a specific EP. These server types are not included in a rebalance or
monitored by another EP when the assigned EP stops running. If you want to unpin these server types
or to include them in a rebalance, in the advanced properties for each server, clear the
