FAQ
What does this tool tell you?
The CloudWatch Metric Math Reference covers all CloudWatch Metric Math functions with syntax, parameters, and examples for dashboard expressions and alarm configurations.
What affects the result most?
CloudWatch Metric Math: PERIOD(), RATE(), FILL(), SEARCH(), IF(), MIN(), MAX(), SUM(), ANOMALY_DETECTION_BAND(). SEARCH() function: finds metrics matching a pattern — SEARCH('{AWS/EC2,InstanceId} MetricName="CPUUtilization"', 'Average', 300). RATE(): converts cumulative counters to per-second rates — essential for NetworkIn/NetworkOut, RequestCount.
How should I use the result?
Use this tool to orient quickly to the concepts, field names, or values you are about to look up in a full specification or vendor documentation. It summarizes the common cases; the authoritative source remains whichever standard or vendor doc defines the values themselves.
