Description

Elevated CPUActivity (Normal Network Activity)

30 min

aws.ec2.cpuutilization has an upper baseline deviation + an upper contextual deviation

netuitive.aws.ec2.bytesinpersec does not have a upper baseline deviation + does not have a upper contextual deviation

netuitive.aws.ec2.bytesoutpersec does not have a upper baseline deviation + does not have a upper contextual deviation

INFO

Increases in CPU activity are not uncommon when there is a rise in network activity. Increased traffic to a server means more work for that server to do. This policy is designed to catch cases where CPU activity is higher than than normal, and said behavior cannot be explained by a corresponding increase in network traffic. It may or may not represent a problem, but it is useful to know about.
