# MetricConfiguration


This structure contains the `Filter` parameter which you can use to specify which metric namespaces are to be shared from this source account to the monitoring account.

## Contents


 ** Filter **   <a name="OAM-Type-MetricConfiguration-Filter"></a>
Use this field to specify which metrics are to be shared with the monitoring account. Use the term `Namespace` and one or more of the following operands. Use single quotation marks (') around namespace names. The matching of namespace names is case sensitive. Each filter has a limit of five conditional operands. Conditional operands are `AND` and `OR`.  
+  `=` and `!=` 
+  `AND` 
+  `OR` 
+  `LIKE` and `NOT LIKE`. These can be used only as prefix searches. Include a `%` at the end of the string that you want to search for and include.
+  `IN` and `NOT IN`, using parentheses `( )` 
Examples:  
+  `Namespace NOT LIKE 'AWS/%'` includes only namespaces that don't start with `AWS/`, such as custom namespaces.
+  `Namespace IN ('AWS/EC2', 'AWS/ELB', 'AWS/S3')` includes only the metrics in the EC2, Elastic Load Balancing, and Amazon S3 namespaces. 
+  `Namespace = 'AWS/EC2' OR Namespace NOT LIKE 'AWS/%'` includes only the EC2 namespace and your custom namespaces.
If you are updating a link that uses filters, you can specify `*` as the only value for the `filter` parameter to delete the filter and share all metric namespaces with the monitoring account.
