Is it possible to have a moving average or a trend line in the metrics of aws cloudwatch?
The idea is to show for example the cpu utilization of a server over time and not just the average of the last x minutes, so we can see if the trend over long period of time is going up or down.
CloudWatch does not have trend lines built into standard metrics.
If you're looking for this you can enable this you would need to setup anomaly detection for the metric.
By enabling this you will be able to build up an overview of the trends for that metric whilst also configuring the normal/abnormal ranges for the metric. If your data goes outside this line you can have a CloudWatch alarm notify you.
