Fluentd v1.9.0 has been released

Hi users!

We have released v1.9.0. ChangeLog is here. This release includes new config reload feature and some enhancements.

New light-weight config reload

We introduce new configuration reload feature. This re-creates only internal pipeline, so this is faster than existing worker-restart model.

You can use this config reload via USR2 signal or /api/config.gracefulReload RPC.

Any feedback would be appreciated.

Drop ruby 2.1/2.2/2.3 support

See Drop schedule announcement in 2019.

Support Ruby's Time class in msgpack serde

Fluentd uses MessagePack format for buffering data by default. This has one limitation: Can't use msgpack ext type for non primitive class.

Since v1.9, Fluentd supports Time class by enable_msgpack_time_support parameter.

  enable_msgpack_time_support true

This is useful when your log contains multiple time fields.

Major bug fixes

  • outut/buffer: Fix stage size computation
  • buffer: Disable the optimization of Metadata instance comparison on Windows to avoid lots of buffer files
  • server: Ignore Errno::EHOSTUNREACH in TLS accept to avoid fluentd restart

Enjoy logging!
