AOS-S Switches with High CPU Utilization
The CPU Central Processing Unit. A CPU is an electronic circuitry in a computer for processing instructions. utilization. It is categorized under availability since the impacted switches and the associated devices experience connectivity issues. This insight displays the following information:
insight can be accessed from the , , and context. This insight provides information on the switches experiencing higher than normalTime Series Graph
In
and context the time series graph displays the count of switches experiencing high CPU utilization in the network during the selected time period. You can hover your mouse on each bar graph to see the number of impacted switches during the selected time under each severity. In the Device context, this graph displays the severity level of the selected switch experiencing high CPU utilization during the selected time period.Cards
The cards vary based on the context that you access the insight from. Click one of the cards to view further details:
