sqs

edit

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:

    {
      "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.

Details

`access_key_id`

edit

Value type is string
There is no default value for this setting.

This plugin uses the AWS SDK and supports several ways to get credentials, which will be tried in this order:

Static configuration, using access_key_id and secret_access_key params in logstash plugin config
External credentials file specified by aws_credentials_file
Environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
Environment variables AMAZON_ACCESS_KEY_ID and AMAZON_SECRET_ACCESS_KEY
IAM Instance Profile (available when running inside EC2)

`add_field`

edit

Value type is hash
Default value is {}

Add a field to an event

`aws_credentials_file`

edit

Value type is string
There is no default value for this setting.

Path to YAML file containing a hash of AWS credentials. This file will only be loaded if access_key_id and secret_access_key aren’t set. The contents of the file should look like this:

 :access_key_id: "12345"
 :secret_access_key: "54321"

`codec`

edit

Value type is codec
Default value is "json"

The codec used for input data. Input codecs are a convenient method for decoding your data before it enters the input, without needing a separate filter in your Logstash pipeline.

`id_field`

edit

Value type is string
There is no default value for this setting.

Name of the event field in which to store the SQS message ID

`md5_field`

edit

Value type is string
There is no default value for this setting.

Name of the event field in which to store the SQS message MD5 checksum

`polling_frequency`

edit

Value type is number
Default value is 20

Polling frequency, default is 20 seconds

`proxy_uri`

edit

Value type is string
There is no default value for this setting.

URI to proxy server if required

`queue`

edit

This is a required setting.
Value type is string
There is no default value for this setting.

Name of the SQS Queue name to pull messages from. Note that this is just the name of the queue, not the URL or ARN.

`region`

edit

Value can be any of: us-east-1, us-west-1, us-west-2, eu-central-1, eu-west-1, ap-southeast-1, ap-southeast-2, ap-northeast-1, sa-east-1, us-gov-west-1, cn-north-1
Default value is "us-east-1"

`secret_access_key`

edit

Value type is string
There is no default value for this setting.

The AWS Secret Access Key

`sent_timestamp_field`

edit

Value type is string
There is no default value for this setting.

Name of the event field in which to store the SQS message Sent Timestamp

`session_token`

edit

Value type is string
There is no default value for this setting.

The AWS Session token for temporary credentials

`tags`

edit

Value type is array
There is no default value for this setting.

Add any number of arbitrary tags to your event.

This can help with processing later.

`threads`

edit

Value type is number
Default value is 1

`type`

edit

Value type is string
There is no default value for this setting.

Add a type field to all events handled by this input.

Types are used mainly for filter activation.

The type is stored as part of the event itself, so you can also use the type to search for it in Kibana.

If you try to set a type on an event that already has one (for example when you send an event from a shipper to an indexer) then a new input will not override the existing type. A type set at the shipper stays with that event for its life even when sent to another Logstash server.
