Conversation
…events only when engine is running) * fix a bug not to enable log events only with "match fluent.**" sections * fixed code will enable log events only with "match fluent.info" sections * route fluent.** events to @FLUENT_LOG label event router if exists * route these events to top-level fluent.** if @FLUENT_LOG missing * in @FLUENT_LOG section, events not matched will be ignored (assuming log-level-ish behavior) * both in @FLUENT_LOG and in top-level, non-matched log event tags will be warned at startup * disable log events in default, and enable it after starting up Engine * it prevent to raise unexpected errors by emitting events to plugins already shut-down

Should we use EventTime for time and passing it to push_log_event without to_i call?

Right... I added a commit to emit events with Fluent::EventTime.from_time(time).

fluent-plugin-reemit uses this class directly. Should keep with constant value.

Oops. Why do the such thing...

I checked the code of out_reemit. It doesn't refer Fluent::NoMatchMatch.
(It just refer Fluent::EngineClass::NoMatchMatch in V10Engine).

Isn't it?

Ah, I see.
I missed the if condition for versions.

Check tag typo is better. Currently, there is no warning with following conf.
<label @FLUENT_LOG>
<match fleunt.info>
@type stdout
</match>
</label>
Log example: There is no 'fluent' prefix <match> in <label @FLUENT_LOG>. Check typo.

I updated the code to warn that <label @FLUENT_LOG> doesn't have any matches for fluent.* tags.

There are some issues and unexpected behavior about log events (
fluent.**events).This change is to fix these problems and add features.
<match fluent.**>sections<match fluent.info>section doesn't work A counter-intuitive behavior for fluent.(error|warn|info|trace) logs #485Added features and changes:
