Versions:
Elastic’s Beats Functionbeat 8.17.3 is a lightweight, single-purpose shipper designed to ingest cloud telemetry into the Elastic Stack without maintaining persistent compute: by deploying itself directly as a serverless function it captures events from AWS Kinesis, CloudWatch Logs, SQS, SNS, or Google Pub/Sub and forwards them to Elasticsearch or Logstash for real-time search, security analytics, and observability. Because the binary runs only when triggered, users pay per invocation instead of keeping a fleet of virtual machines idle, making the tool attractive for DevOps teams that need to monitor bursty workloads, audit cloud API activity, or stream high-volume log data from multi-account environments while keeping operational cost and complexity low. The same 8.17.3 release incorporates the standard Beats framework—common fields, back-pressure management, TLS encryption, and central template management—so administrators can apply consistent parsing, indexing, and retention policies across Functionbeat and other Elastic shippers such as Filebeat or Metricbeat. Deployment is handled through a single command-line binary that packages the function artifact, creates the necessary IAM roles, and uploads the code to the chosen cloud provider; once active, the function scales automatically with incoming event volume and can be updated or rolled back without downtime. Functionbeat therefore fits the “Log Management & Analysis” software category and is especially useful for organizations adopting infrastructure-as-code practices that want to extend observability into serverless services without adding another always-on layer. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
