An HTML page showing the most recent and detailed graphs for each interface on the device is displayed, along with IO Errors for each interface and CPU utilisation on supported devices. All of the graphs on this device page are linked to more detailed views with four graphs being generated that show the information over progressively longer periods. • If HP OpenView is collecting any numeric SNMP data from the “Data Collections & Thre
