  - `path` - (Required) The location to scan for new data.
-     + `bucket_name` - (Required) The name of the bucket.
-     + `path_expression` - (Required) The path to the data.
+     + `type` - (Required) type of polling source. Can be one of `S3BucketPathExpression` or  `CloudWatchPath`
+     + `bucket_name` - (Optional) The name of the bucket. This is needed if using type `S3BucketPathExpression`. 
+     + `path_expression` - (Optional) The path to the data. This is needed if using type `S3BucketPathExpression`.

This is a valid parameter if using type `CloudWatchPath` More info on tag filters can be found [here](https://help.sumologic.com/03Send-Data/Sources/02Sources-for-Hosted-Collectors/Amazon-Web-Services/Amazon-CloudWatch-Source-for-Metrics#about-aws-tag-filtering)
+          + `type` - This value has to be set to `TagFilters`
+          + `namespace` - Namespace for which you want to define the tag filters. Use  value as `All` to apply the tag filter for all namespaces.
+          + `tags` - List of key-value pairs of tag filters. Eg: `["k3=v3"]`
