Promtail Log Collector
Introduction
Promtail is an open-source log collector developed by Grafana Labs, designed to work seamlessly with Loki, a log aggregation system. Promtail is responsible for gathering logs from various sources, processing them, and sending them to Loki for storage and querying. It is particularly well-suited for Kubernetes environments but can also be used in other contexts.
Promtail is now deprecated and will enter into Long-Term Support (LTS) beginning Feb. 13, 2025. This means that Promtail will no longer receive any new feature updates, but it will receive critical bug fixes and security fixes. Commercial support will end after the LTS phase, which we anticipate will extend for about 12 months until February 28, 2026. End-of-Life (EOL) phase for Promtail will begin once LTS ends. Promtail is expected to reach EOL on March 2, 2026, afterwards no future support or updates will be provided. All future feature development will occur in Grafana Alloy.
