CLI

AWS CLI

Untuk mendapatkan atribut antrian

Contoh ini mendapatkan semua atribut antrian yang ditentukan.

Perintah:

aws sqs get-queue-attributes --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyQueue --attribute-names All

Output:

{
  "Attributes": {
    "ApproximateNumberOfMessagesNotVisible": "0",
    "RedrivePolicy": "{\"deadLetterTargetArn\":\"arn:aws:sqs:us-east-1:80398EXAMPLE:MyDeadLetterQueue\",\"maxReceiveCount\":1000}",
    "MessageRetentionPeriod": "345600",
    "ApproximateNumberOfMessagesDelayed": "0",
    "MaximumMessageSize": "262144",
    "CreatedTimestamp": "1442426968",
    "ApproximateNumberOfMessages": "0",
    "ReceiveMessageWaitTimeSeconds": "0",
    "DelaySeconds": "0",
    "VisibilityTimeout": "30",
    "LastModifiedTimestamp": "1442426968",
    "QueueArn": "arn:aws:sqs:us-east-1:80398EXAMPLE:MyNewQueue"
  }
}

Contoh ini hanya mendapatkan ukuran pesan maksimum antrian yang ditentukan dan atribut batas waktu visibilitas.

Perintah:

aws sqs get-queue-attributes --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyNewQueue --attribute-names MaximumMessageSize VisibilityTimeout

Output:

{
  "Attributes": {
    "VisibilityTimeout": "30",
    "MaximumMessageSize": "262144"
  }
}
