[2.1.2] - 2024-03-19

Fixed

• Resolved a bug where upgrading from versions earlier than 2.1.0 led to the loss of S3 notifications, preventing the proper collection of logs from the S3 buffer. (Main Stack): Upgrading from a version below 2.1.0 caused the loss of S3 notifications, and the logs from S3 buffer cannot be collected properly. #261
• Addressed a problem where including the @timestamp field in log configurations caused failures in creating index_templates, leading to an inability to write data to OpenSearch. (AppPipeline): If the log configuration includes the "@timestamp" field, it will result in the inability to create an index_template, and the data cannot be written to OpenSearch. #262
• Fixed a bug in the log processor Lambda due to the absence of the 'batch_size' variable, causing process failures. log-processor: lambda failing because of missing variable 'batch_size' #242
• Solved a deployment issue with the Log Analytics Pipeline, which previously could not deploy cross-account Lambda pipelines. Log Analytics Pipeline: Unable to deploy cross account lambda pipelines #227
• Corrected an issue with the ALB Service Log Parser that resulted in the omission of numerous log lines. ELB Service: Log Parser skipping lots of lines #243
• Amended an inaccurate warning message displayed during pipeline creation with an existing index in OpenSearch. Wrong warning message when creating pipeline with existing index in OpenSearch #260
• Amended an inaccurate error messaging when deleting an Instance Group in application log pipelines. Application Logs: Wrong error message when deleting an instance group #229
