Problem with Cloudwatch Input Login for ECS Namespace

Hi,

I am trying send AWS/ECS metrics from cloudwatch to kibana using logstash.
Below is my config
input {
cloudwatch {
"access_key_id" => "XXXXXXXXXXXX"
"secret_access_key" => "XXXXXXXXX"
#role_arn => "XXXXXXXXXXXXXXXXXXXXX"
namespace => "AWS/ECS"
#schedule => "/30 * * * * *"
metrics => ["CPUUtilization", "MemoryUtilization"]
filters => { "ClusterName" => "awscontainer" }
filters => { "ServiceName" => "aws-ecs" }
region => "us-east-1"
type => "cloudwatch"
}
}

filter {
date {
match => [ "start_time","ISO8601" ]
target => "@timestamp"
}
}
output {
elasticsearch {
hosts => ["xxxxxxxxxxxxxxx-cloud.com:9243"]
index => "xxxxxxxxxxx"
user => "xxxxxxxxxxxxx"
password => "xxxxxxxxxxxxx"
}
stdout {
codec => rubydebug
}
}
Below is my execution record.

I am getting the above execution record, when I run the logstash. I am not sure it's puling AWS/ECS metrics from cloudwatch and there is no error and I don't see any events in Kibana.
Can some one please help me on this.

Thanks in advance.
