Fluent Bit

by Fluent Inc.
Observability

Deploys the upstream fluent/fluent-bit Helm chart from the CNCF Fluent project. Fluent Bit is a fast, lightweight log processor and forwarder designed for cloud-native environments. By default this product runs as a DaemonSet (one pod per node) that picks up container logs from each node’s kubelet and ships them to the configured outputs. The plugin ecosystem supports inputs from systemd, kubernetes events, syslog, and outputs to Loki, Elasticsearch, Kafka, S3, Splunk, and more.

Key features
