=== Sqs input plugin

include::{include_path}/plugin_header.asciidoc[]

==== Description


Pull events from an Amazon Web Services Simple Queue Service (SQS) queue.

SQS is a simple, scalable queue system that is part of the
Amazon Web Services suite of tools.

Although SQS is similar to other queuing systems like AMQP, it
uses a custom API and requires that you have an AWS account.
See http://aws.amazon.com/sqs/ for more details on how SQS works,
what the pricing schedule looks like and how to setup a queue.

To use this plugin, you *must*:

 * Have an AWS account
 * Setup an SQS queue
 * Create an identify that has access to consume messages from the queue.

The "consumer" identity must have the following permissions on the queue:

 * `sqs:ChangeMessageVisibility`
 * `sqs:ChangeMessageVisibilityBatch`
 * `sqs:DeleteMessage`
 * `sqs:DeleteMessageBatch`
 * `sqs:GetQueueAttributes`
 * `sqs:GetQueueUrl`
 * `sqs:ListQueues`
 * `sqs:ReceiveMessage`

Typically, you should setup an IAM policy, create a user and apply the IAM policy to the user.
A sample policy is as follows:
[source,json]
    {
      "Statement": [
        {
          "Action": [
            "sqs:ChangeMessageVisibility",
            "sqs:ChangeMessageVisibilityBatch",
            "sqs:GetQueueAttributes",
            "sqs:GetQueueUrl",
            "sqs:ListQueues",
            "sqs:SendMessage",
            "sqs:SendMessageBatch"
          ],
          "Effect": "Allow",
          "Resource": [
            "arn:aws:sqs:us-east-1:123456789012:Logstash"
          ]
        }
      ]
    }

See http://aws.amazon.com/iam/ for more details on setting up AWS identities.
