Genesys Cloud's Event Viewer provides a centralized interface for monitoring and troubleshooting campaign-related errors in outbound operations. Accessible through Admin > Outbound > Event Viewer or Menu > Digital and Telephony > Outbound > Event Viewer, the tool displays event details including timestamp, level, and category for each campaign error. Users can sort events by level or category to facilitate analysis, with each event containing detailed information to support troubleshooting efforts. The system automatically expires events after 30 days. Access to the Event Viewer requires the Outbound > Eventlog > View permission. When errors occur in running campaigns, the system generates events assigned specific categories and levels, enabling administrators to identify and resolve issues affecting campaign performance.
