Description

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 identity 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:DeleteMessage",
            "sqs:DeleteMessageBatch",
            "sqs:GetQueueAttributes",
            "sqs:GetQueueUrl",
            "sqs:ListQueues",
            "sqs:ReceiveMessage"
          ],
          "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.

Sqs Input Configuration Options

edit

This plugin supports the following configuration options plus the Common options described later.

Also see Common options for a list of options supported by all input plugins.

 

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:

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

additional_settings

edit
  • Value type is hash
  • Default value is {}

Key-value pairs of settings and corresponding values used to parametrize the connection to SQS. See full list in the AWS SDK documentation. Example:

    input {
      sqs {
        access_key_id => "1234"
        secret_access_key => "secret"
        queue => "logstash-test-queue"
        additional_settings => {
          force_path_style => true
          follow_redirects => false
        }
      }
    }

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"

endpoint

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

The endpoint to connect to. By default it is constructed using the value of region. This is useful when connecting to S3 compatible services, but beware that these aren’t guaranteed to work correctly with the AWS SDK.

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.

queue_owner_aws_account_id

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

ID of the AWS account owning the queue if you want to use a cross-account queue with embedded policy. Note that AWS SDK only support numerical account ID and not account aliases.

region

edit
  • Value type is string
  • Default value is "us-east-1"

The AWS Region

role_arn

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

The AWS IAM Role to assume, if any. This is used to generate temporary credentials, typically for cross-account access. See the AssumeRole API documentation for more information.

role_session_name

edit
  • Value type is string
  • Default value is "logstash"

Session name to use when assuming an IAM role.

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 credential

threads

edit
  • Value type is number
  • Default value is 1

use_aws_bundled_ca

edit
  • Value type is boolean
  • Default value is false

Use bundled CA certificates that ship with AWS SDK to verify SSL peer certificates. For cases where the default certificates are unavailable, e.g. Windows, you can set this to true.

Common options

edit

These configuration options are supported by all input plugins:

Setting Input type Required

add_field

hash

No

codec

codec

No

enable_metric

boolean

No

id

string

No

tags

array

No

type

string

No

add_field

edit
  • Value type is hash
  • Default value is {}

Add a field to an event

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.

enable_metric

edit
  • Value type is boolean
  • Default value is true

Disable or enable metric logging for this specific plugin instance by default we record all the metrics we can, but you can disable metrics collection for a specific plugin.

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

Add a unique ID to the plugin configuration. If no ID is specified, Logstash will generate one. It is strongly recommended to set this ID in your configuration. This is particularly useful when you have two or more plugins of the same type, for example, if you have 2 sqs inputs. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

input {
  sqs {
    id => "my_plugin_id"
  }
}

Variable substitution in the id field only supports environment variables and does not support the use of values from the secret store.

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.

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.
