February 2026 monthly summary for the influxdata/telegraf project. Key feature delivered: Redis TTL support for the redistimeseries output plugin, enabling configured time-to-live for Redis keys so they expire after a specified duration when no new data is written. This improves data lifecycle management, reduces Redis memory usage, and helps prevent stale metrics from persisting. The work was completed with a dedicated commit introducing the TTL option in the redistimeseries output path. There were no reported major bugs fixed this month. Overall impact includes better resource utilization, stronger data retention controls, and alignment with Redis-backed metrics strategies. Technologies demonstrated include Redis TTL concepts, Telegraf plugin architecture and Go-based plugin development, and collaborative development practices (co-authored commits).
