--loadbalancer LOADBALANCER
Classic Load Balancer provides basic load balancing across multiple Amazon EC2 instances and operates at both the request level and connection level. For example: awseb-e-m-AWSEBLoa-Numbers&Characters

--period PERIOD
A period is the length of time associated with a specific Amazon CloudWatch statistic.

--statistics STATISTICS
Statistics are metric data aggregations over specified periods of time.
For example: Average

--unit UNIT
Each statistic has a unit of measure.
For example: Count

--ok_threshold OK_THRESHOLD
Threshold which reflects the OK status value. (Recommended threshold: 0)

--critical_threshold CRITICAL_THRESHOLD
Threshold which reflects the Critical status value. (Recommended threshold: 0)

--namespace NAMESPACE
CloudWatch namespaces are containers for metrics.
For example: AWS/ECS

--metricname METRICNAME
Metrics are data about the performance of your systems.
For example: MemoryUtilization

--clustername CLUSTERNAME
This dimension filters the data you request for all resources in a specified cluster.

--servicename SERVICENAME
This dimension filters the data you request for all resources in a specified service within a specified cluster.

--period PERIOD
A period is the length of time associated with a specific Amazon CloudWatch statistic.
For example: to specify a period of 5 minutes, use 300 as the period value.

--statistics STATISTICS
Statistics are metric data aggregations over specified periods of time.
For example: Average

--unit UNIT
Each statistic has a unit of measure.
For example: Percent

--ok_threshold OK_THRESHOLD
Threshold which reflects the OK status value. (Recommended threshold: 86)

--warning_threshold WARNING_THRESHOLD
Threshold which reflects the Warning status value. (Recommended threshold: 86)
