Functionbeat is a serverless data ingestion tool that integrates with Elasticsearch, providing a streamlined approach to ingesting cloud data from services like AWS Lambda. It functions as part of the Beats product suite, allowing users to deploy it on serverless compute platforms to efficiently process and ship events such as logs and metrics from cloud infrastructure to Elasticsearch. Initially supporting AWS Cloudwatch Logs and SQS, Functionbeat is designed to expand its compatibility with more cloud providers and data sources over time. Users can configure Functionbeat through a user-friendly interface without needing to write code, enabling the transformation, enrichment, and routing of data. It operates similarly to other Beats, such as Filebeat and Metricbeat, and is freely available under the Elastic Basic license, encouraging feedback and contributions from its open-source community as it progresses towards general availability.
