Alarm History Report


The Alarm History report is a standardized report generated in Edge Services Director for all managed service delivery gateway (SDG) devices that are visible to Edge Services Director. It shows all active, acknowledged, and cleared alarms that occurred within a specified period of time for the indicated node. This report can be generated for the entire network, or for the managed service delivery gateways (SDGs) or SDG groups in the All Network tree of the View pane in Gateway mode. The report has two portions: a report header and the report body.
