AWS SDK 또는 CLI와 함께 ListTargetsByRule 사용

규칙 이름을 사용하여 규칙의 모든 대상을 나열합니다.

    /// <summary>
    /// List all of the targets matching a rule by name.
    /// </summary>
    /// <param name="ruleName">The name of the rule.</param>
    /// <returns>The list of targets.</returns>
    public async Task<List<Target>> ListAllTargetsOnRule(string ruleName)
    {
        var results = new List<Target>();
        var request = new ListTargetsByRuleRequest()
        {
            Rule = ruleName
        };
        ListTargetsByRuleResponse response;
        do
        {
            response = await _amazonEventBridge.ListTargetsByRuleAsync(request);
            results.AddRange(response.Targets);
            request.NextToken = response.NextToken;

        } while (response.NextToken is not null);

        return results;
    }

CloudWatch 이벤트 규칙의 모든 대상을 표시하는 방법

이 예시에서는 DailyLambdaFunction이라는 규칙의 모든 대상을 표시합니다.

aws events list-targets-by-rule --rule  "DailyLambdaFunction"

규칙 이름을 사용하여 규칙의 모든 대상을 나열하세요.

    public static void listTargets(EventBridgeClient eventBrClient, String ruleName) {
        ListTargetsByRuleRequest ruleRequest = ListTargetsByRuleRequest.builder()
                .rule(ruleName)
                .build();

        ListTargetsByRuleResponse res = eventBrClient.listTargetsByRule(ruleRequest);
        List<Target> targetsList = res.targets();
        for (Target target: targetsList) {
            System.out.println("Target ARN: "+target.arn());
        }
    }

suspend fun listTargets(ruleName: String?) {
    val ruleRequest =
        ListTargetsByRuleRequest {
            rule = ruleName
        }

    EventBridgeClient { region = "us-east-1" }.use { eventBrClient ->
        val response = eventBrClient.listTargetsByRule(ruleRequest)
        response.targets?.forEach { target ->
            println("Target ARN: ${target.arn}")
        }
    }
