Gateways with High CPU Utilization
The insight can be accessed from the , , and context. This insight provides information about gateways that have higher than normal CPU Central Processing Unit. A CPU is an electronic circuitry in a computer for processing instructions. utilization. It is categorized under availability since the clients connected to these gateways experience intermittent connectivity drops. This insight displays the following information:
Time Series Graph
The time series graph displays the percentage of impacted gateways in the network during the selected time period. You can hover your mouse over each bar graph to see the percentage of impacted gateways.
