# Viewing service-linked channels
AWS services can create a service-linked channel to receive CloudTrail events on your behalf. The AWS service creating the service-linked channel configures advanced event selectors for the channel and specifies whether the channel applies to all AWS Regions, or a single AWS Region.

## Viewing service-linked channels by using the console
Using the CloudTrail console, you can view information about any CloudTrail service-linked channels created by AWS services. The table is empty if your account does not have any service-linked channels.
Use the following procedure to view information about a service-linked channel.
1. Choose **Settings** in the left navigation pane of the CloudTrail console.
1. From **Service-linked channels**, choose a service-linked channel to view its details.
1. On the details page, review the configured settings for the service-linked channel.
You can view the following information on the details page.
+ **Channel name** - The full name of the channel. The channel name format is `aws-service-channel/AWS_service_name/slc` where `AWS_service_name` represents the name of the AWS service that manages the channel.
+ **Channel ARN** - The ARN of the channel, which you can use in a API request to get details about the channel.
+ **All regions** - The value is `Yes` if the channel is configured for all AWS Regions.
+ **AWS service** - The name of the AWS service managing the channel.
+ **Management events** - Shows any management events configured for the channel.
+ **Data events** - Shows any data events configured for the channel.
## Viewing service-linked channels by using the AWS CLI
Using the AWS CLI, you can view information about any CloudTrail service-linked channels created by AWS services.

### Get a CloudTrail service-linked channel
The following example AWS CLI command returns information about a specific CloudTrail service-linked channel, including the name of the destination AWS service, any advanced selectors configured for the channel, and whether the channel applies to all Regions or a single Region.
You must specify an ARN or the ID suffix of an ARN for `--channel`.
```
aws cloudtrail get-channel --channel EXAMPLE-ee54-4813-92d5-999aeEXAMPLE
```
The following is an example response. In this example, `AWS_service_name` represents the name of the AWS service that created the channel.
```
{
"ChannelArn": "arn:aws:cloudtrail:us-east-1:111122223333:channel/EXAMPLE-ee54-4813-92d5-999aeEXAMPLE",
"Name": "aws-service-channel/AWS_service_name/slc",
"Source": "CloudTrail",
"SourceConfig": {
"ApplyToAllRegions": false,
"AdvancedEventSelectors": [
{
"Name": "Management Events Only",
"FieldSelectors": [
{
"Field": "eventCategory",
"Equals": [
"Management"
]
}
]
}
]
},
"Destinations": [
{
"Type": "AWS_SERVICE",
"Location": "AWS_service_name"
}
]
}
```
### List all CloudTrail service-linked channels
The following example AWS CLI command returns information about all CloudTrail service-linked channels that were created on your behalf. Optional parameters include `--max-results`, to specify a maximum number of results that you want the command to return on a single page. If there are more results than your specified `--max-results` value, run the command again adding the returned `NextToken` value to get the next page of results.
```
aws cloudtrail list-channels
```
The following is an example response. In this example, `AWS_service_name` represents the name of the AWS service that created the channel.
```
{
"Channels": [
{
"ChannelArn": "arn:aws:cloudtrail:us-east-1:111122223333:channel/EXAMPLE-ee54-4813-92d5-999aeEXAMPLE",
"Name": "aws-service-channel/AWS_service_name/slc"
}
]
}
```
### AWS service events on service-linked channels
The AWS service managing the service-linked channel can initiate actions on the service-linked channel (for example, creating or updating a service-linked channel). CloudTrail logs these actions as [AWS service events](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/non-api-aws-service-events.html), and delivers these events to the **Event history**, and any active trails and event data stores configured for management events. For these events, the `eventType` field is `AwsServiceEvent`.
The following is an example log file entry of an AWS service event for creation of a service-linked channel.
```
