Buffer files remain after restart of fluentd about fluentd HOT 5 OPEN

./worker0

Where is this directory?

You can avoid this problem by improving the setting.
Currently, you don't set path of buffer.
So, out_file sets the buffer path automatically to out_file's path.
You can set a more simple and safe path for buffer.

./worker0

Where is this directory?

The buffer file directory structure is located in /application/diagnostics/${tag[0]}/${tag[2]}/${tag[3]}-%Y-%m-%d. This folder contains the folders worker[0-7].
The same pattern is present for the second path template /application/diagnostics/${tag[1]}/${tag[3]}/${tag[1]}-%Y-%m-%d.

Thanks for your report.
I found a bug.
When the buffer path includes [ or ], the resuming process can not find the remaining files.
This is caused by the lack of escapes.

@daipom This sounds promising. I'll check out, but unfortunately we couldn't put the story on the topic into the current sprint 😞 I'll check in 2 weeks again!
