Event processors

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 EP.

If you have the administrator permission of IBM Control Center Monitor, you can rebalance your server assignments among EPs in the same cluster, including EPs that are not running. To do so, go to Manage > Event processors 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 Pin this server to the currently assigned event processor setting.
