Creates or updates a subscription filter and associates it with the specified log group. Subscription filters allow you to subscribe to a real-time stream of log events ingested through PutLogEvents and have them delivered to a specific destination. When log events are sent to the receiving service, they are Base64 encoded and compressed with the gzip format.

The following destinations are supported for subscription filters:

There can only be one subscription filter associated with a log group. If you are updating an existing filter, you must specify the correct name in filterName. Otherwise, the call fails because you cannot associate a second filter with a log group.

To perform a PutSubscriptionFilter operation, you must also have the iam:PassRole permission.


This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginPutSubscriptionFilter and EndPutSubscriptionFilter.
