Description

edit

SNS output.

Send events to Amazon’s Simple Notification Service, a hosted pub/sub framework. It supports various subscription types, including email, HTTP/S, SMS, and SQS.

For further documentation about the service see:

http://docs.amazonwebservices.com/sns/latest/api/

This plugin looks for the following fields on events it receives:

  • sns - If no ARN is found in the configuration file, this will be used as the ARN to publish.
  • sns_subject - The subject line that should be used. Optional. The "%{host}" will be used if sns_subject is not present. The subject will be truncated to 100 characters. If sns_subject is set to a non-string value a JSON version of that value will be saved.
  • sns_message - Optional string of message to be sent. If this is set to a non-string value it will be encoded with the specified codec. If this is not set the entire event will be encoded with the codec. with the @message truncated so that the length of the JSON fits in 32768 bytes.

Upgrading to 2.0.0

edit

This plugin used to have a format option for controlling the encoding of messages prior to being sent to SNS. This plugin now uses the logstash standard codec option for encoding instead. If you want the same plain format as the v0/1 codec (format => "plain") use codec => "s3_plain".

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)

arn

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

Optional ARN to send messages to. If you do not set this you must include the sns field in your events to set the ARN on a per-message basis!

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"

proxy_uri

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

URI to proxy server if required

publish_boot_message_arn

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

When an ARN for an SNS topic is specified here, the message "Logstash successfully booted" will be sent to it when this plugin is registered.

Example: arn:aws:sns:us-east-1:770975001275:logstash-testing

region

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

The AWS Region

secret_access_key

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

The AWS Secret Access Key

session_token

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

The AWS Session token for temporary credential

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

The following configuration options are supported by all output plugins:

Setting Input type Required

codec

codec

No

enable_metric

boolean

No

id

string

No

codec

edit
  • Value type is codec
  • Default value is "plain"

The codec used for output data. Output codecs are a convenient method for encoding your data before it leaves the output 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 sns outputs. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

output {
  sns {
    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.
