Use ListRuleNamesByTarget
with an Amazon SDK or CLI
The following code examples show how to use ListRuleNamesByTarget
.
Action examples are code excerpts from larger programs and must be run in context. You can see this action in
context in the following code example:
- .NET
-
- Amazon SDK for .NET
-
List all of the rule names using the target.
/// <summary>
/// List names of all rules matching a target.
/// </summary>
/// <param name="targetArn">The ARN of the target.</param>
/// <returns>The list of rule names.</returns>
public async Task<List<string>> ListAllRuleNamesByTarget(string targetArn)
{
var results = new List<string>();
var request = new ListRuleNamesByTargetRequest()
{
TargetArn = targetArn
};
ListRuleNamesByTargetResponse response;
do
{
response = await _amazonEventBridge.ListRuleNamesByTargetAsync(request);
results.AddRange(response.RuleNames);
request.NextToken = response.NextToken;
} while (response.NextToken is not null);
return results;
}

To display all the rules that have a specified target
This example displays all rules that have the Lambda function named "MyFunctionName" as the target:
aws events list-rule-names-by-target --target-arn "arn:aws:lambda:us-east-1:123456789012:function:MyFunctionName"
- Java
-
- SDK for Java 2.x
-
List all of the rule names by using the target.
public static void listTargetRules(EventBridgeClient eventBrClient, String topicArn) {
ListRuleNamesByTargetRequest ruleNamesByTargetRequest = ListRuleNamesByTargetRequest.builder()
.targetArn(topicArn)
.build();
ListRuleNamesByTargetResponse response = eventBrClient.listRuleNamesByTarget(ruleNamesByTargetRequest);
List<String> rules = response.ruleNames();
for (String rule : rules) {
System.out.println("The rule name is " + rule);
}
}
- Kotlin

- SDK for Kotlin
-
suspend fun listTargetRules(topicArnVal: String?) {
val ruleNamesByTargetRequest =
ListRuleNamesByTargetRequest {
targetArn = topicArnVal
}
EventBridgeClient { region = "us-east-1" }.use { eventBrClient ->
val response = eventBrClient.listRuleNamesByTarget(ruleNamesByTargetRequest)
response.ruleNames?.forEach { rule ->
println("The rule name is $rule")
}
}
}
