Amazon CloudWatch Metric Math now supports additional functions
Amazon CloudWatch Metric Math now supports sort, slice, remove empty and conditional statements. With CloudWatch Metric Math, you can aggregate and transform metrics to create custom visualizations of your health and performance metrics. The new functions announced today allow you to sort metrics by performance indicators, slice the results to retrieve the highest or lowest values, and apply conditional logic using IF/AND/OR statements. All the new functions can be used to define alarms that take actions like sending notifications and auto scaling your service.
