Fluentd v1.11.2 has been released

Hi users!

We have released v1.11.2. ChangeLog is here.

Allow regular expression in filter/match tag matching

Regular expression, /pattern/, is now allowed in tag matching:

  @type forward

# For a.xxx tag
<filter a.**>
  @type record_transformer
    new_key a-started tag record

# For non a.xxx tag like b.xxx/c.xxx/...
<filter /(?!a\.).*/>
  @type record_transformer
    new_key other tag record

<match **>
  @type stdout

If you send following events:

% echo '{"msg":"hi"}' | fluent-cat a.foo
% echo '{"msg":"hi"}' | fluent-cat b.foo

the log shows:

2020-08-06 13:40:03.111196000 +0900 a.foo: {"msg":"hi","new_key":"a-started tag record"}
2020-08-06 13:40:09.492380000 +0900 b.foo: {"msg":"hi","new_key":"other tag record"}

Of course, simple data pipeline is important for robust log collection. If you need this feature, check your configuration/data flow first.

in_dummy is renamed in_sample

We recommend to use sample instead of dummy:

  @type sample
  sample {"hello":"world"}

# If you use fluentd v1.11.1 or earlier, use following configuration
# Fluentd v2 will remove old configuration support
  @type dummy
  dummy {"hello":"world"}

Major bug fixes

  • buffer: Fix log message for chunk_limit_records case
  • buffer: Fix timekey optimization for non-windows platform
  • cert: Raise an error for broken certificate file
  • cert: Set TLS ciphers list correcty on older OpenSSL, e.g. openssl v1.0.2

Enjoy logging!
