Fluentd v1.3.0 has been released

Hi users!

We have released v1.3.0. ChangeLog is here.

Output: Change thread execution control

This is internal change of output plugin. This change should fix unexpected error like zlib's DataError.

Output: Change default value of queued_chunks_limit_size

queued_chunks_limit_size is now same as flush_thread_count when queued_chunks_limit_size is not specified.

Before, queued_chunks_limit_size is unlimited. This causes critical situation with smaller flush_interval when the destinaion has a problem. For example, lots of very small queued buffer are created and it causes resource limit error.

Unlimited queued buffer is unexpected behaviour, so we changed this behaviour for safety.

in_syslog: octet counting support

We introduced frame_type parameter. With frame_type octet_count configuration, in_syslog accepts octet counting messages like below.

44 <6>Sep 10 00:00:00 localhost logger: hello!

Major bug fixes

• server: Fix deadlock between on_writable and close in sockets. This fixes fluentd restart issue with in_forward's TLS setting error.

Other improvements

• in_http: Add support for CORS preflight requests. Now you can send cross-domain AJAX requests with JSON payload to Fluentd.

Fluentd v1.2.2 has been released

Hi users!

We have released v1.2.2. ChangeLog is here. This release is mainly for bug fixes.

filter_parser: Add remove_key_name_field parameter

With reserve_data true, key_name field is kept in the record.

Original record:

{"k1":"v1","log":"{\"k2\":\"v2\"}"}

Parsed result:

{"k1":"v1","log":"{\"k2\":\"v2\"}","k2":"v2"}

But we often don't need original key_name field when parsing is succeeded. You can remove key_name field with remove_key_name_field true. Parsed result is below:

{"k1":"v1","k2":"v2"}

Major bug fixes

• buffer: Wait for all chunks being purged before deleting @queued_num items

Thanks for submitting bug reports and patches :)

Enjoy logging!
