## CPU and memory utilization

+ The alarm changes state if the container CPU utilization or memory utilization exceed 70% within 1 minute.
+ Our scaling policies’ target is 50%. If these alarms change state, it means the solution’s Auto Scaling is not working.
+ You might need to check if Auto Scaling is turned on or adjust the Auto Scaling settings.
+ The alarm returns to the `OK` state if the CPU utilization and memory utilization are within the acceptable threshold for 5 minutes.
+ Metric: `CPUUtilization` > 70%, `MemoryUtilization` > 70%
