AWS EC2 Policies

Policy names are prefixed with AWS EC2 –

Policy name Duration Condition 1 (and) Condition 2 (and) Condition 3 Cat. Description
Elevated CPUActivity (Normal Network Activity) 30 min aws.ec2.cpuutilization has an upper baseline deviation + an upper contextual deviation metricly.aws.ec2.bytesinpersec does not have a upper baseline deviation + does not have a upper contextual deviation metricly.aws.ec2.bytesoutpersec does not have a upper baseline deviation + does not have a upper contextual deviationn 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.
Elevated Network Activity 30 min metricly.aws.ec2.bytesinpersec has an upper baseline deviation + an upper contextual deviation metricly.aws.ec2.bytesoutpersec has an upper baseline deviation + an upper contextual deviation INFO Indicates an increase in network activity above what is considered to be normal.
ElevatedEphemeral Disk Activity 30 min metricly.aws.ec2.diskreadopspersec has an upper baseline deviation + an upper contextual deviation metricly.aws.ec2.diskwriteopspersec has an upper baseline deviation + an upper contextual deviation INFO Indicates an increase in disk activity above what is considered to be normal.
ElevatedEphemeral Disk Activity 30 min aws.ec2.cpuutilization has a static threshold >95% WARNING The CPU on the EC2 instance has exceeded 95% for at least 15 minutes.
