This enables us to perform calculations across multiple metrics for real-time analysis, so we can easily derive insights from our existing metrics. using a set of mathematical expressions and functions, CloudWatch metrics math allows us to query multiple CloudWatch metrics and use math expressions to create new time series data streams based on our existing metrics. Let's go ahead and see how we can implement this. In CloudWatch, navigate to all metrics, and in here first, we need to select some metrics.
