Known Issues

edit

Auditbeat

Auditbeat/auditd integration will send malformed data and may crash in version 8.4.0. 32818

Suggested resolution: Do not start Auditbeat or auditd integration on Elastic Agent at version 8.4.0. Skip 8.4.0 and upgrade directly to 8.4.1.

This issue is resolved in 8.4.1 and later.

Filebeat

Filebeat agents configured to read from AWS inputs may return an error similar to the following:

sqs ReceiveMessage failed: operation error SQS: ReceiveMessage, https response
error StatusCode: 403, RequestID: cb57783a-505f-5099-9160-23b8eea8ddbb,
api error SignatureDoesNotMatch: Credential should be scoped to a valid region.

This error was introduced by a breaking change in the AWS library.

This issue also affects FIPS-enabled endpoints. If you rely on FIPS, do not upgrade until version 8.4.2 of the Elastic Stack is available. The workaround documented here will not resolve this problem.

Suggested resolution: In the Filebeat configuration, if an AWS input or module configuration sets endpoint to a non empty string, set it to an empty string instead. Also make sure the default AWS region is set in an environment variable, credentials or instance profile, or in the default_region setting in the configuration. For example:

filebeat.inputs:
- type: aws-s3
...
  endpoint: "" 
  default_region: us-east-1

You can set this value to an empty string or remove the configuration setting.

Or for modules:

s3access:
    enabled: false
...
    var.endpoint: "" 
    var.default_region: us-east-1

You can set this value to an empty string or remove the configuration setting
