Managing requestors

Use the Requestors page in Admin Studio to monitor and debug requestor activity. The Requestors page displays summary information about the requestors in the Pega Platform : Application, Browser, Batch, and Portal types. The Requestor Management tab lists all the active requestors in a specific cluster or node.

To access the Requestor Management landing page, view performance, and trace entry details, you must have the PegaRULES:SysOpsObserver role. To perform most actions on requestors, you must also have PegaRULES:SysOpsAdministrator role. To trace requestors and view the clipboard, you must also have the pzDebugRemoteRequestor privilege.
