@ -63,15 +63,10 @@ Name | Description
`namespaces()` | Returns a list of namespaces CloudWatch support.
`metrics(namespace)` | Returns a list of metrics in the namespace.
`dimension_keys(namespace)` | Returns a list of dimension keys in the namespace.
`dimension_values(region, namespace, metric)` | Returns a list of dimension values matching the specified `region`, `namespace` and `metric`.
`dimension_values(region, namespace, metric, dimension_key)` | Returns a list of dimension values matching the specified `region`, `namespace`, `metric` and `dimension_key`.
For details about the metrics CloudWatch provides, please refer to the [CloudWatch documentation](https://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/CW_Support_For_AWS.html).
If you want to filter dimension values by other dimension key/value pair, you can specify optional parameter like this.
```sql
dimension_values(region, namespace, metric, dim_key1=dim_val1,dim_key2=dim_val2,...)
```
