Any help would be appreciated.

[liuxinbot]

The problem should be that the log line is too long beyond the fluentbit buffer, but I am curious why it read from the first line of the log again.

[edsiper]

@liuxin95

thanks for reporting this issue.

I did some local tests with the information provided and these are my findings:

• The file offset is never going back, meaning it never start reading from a previous position. Tested on normal mode and multiline mode. Behavior is expected.
• When a long line is found, an error message is triggered and the file is not longer monitored. If you want to skip the long lines and continue processing other lines just append 'Skip_Long_Lines On' to the input tail section of your file.

@edsiper

Thank you very much for taking the time to reply.

As you said, my solution is also append 'Skip_Long_Lines On' to the input tail section to skip the long lines and continue processing other lines and it works fine.

But for the rigorous work attitude, I run a docker container to collect mycat log and print to stdout, when reading long logs, the fluentbit print info as
[2018/09/04 02:05:04] [error] [in_tail] file=/conf/mycat.log requires a larger buffer size, lines are too long. Skipping file..
Everything is as we expected but After half a minute or so，the fluentbit collect mycat log again. I found a clue from the output information
[2018/09/04 02:06:04] [debug] [in_tail] append new file: /conf/mycat.log.
Detailed information is as follows：

[root@10-10-88-198 fluentbit]# docker run -ti -v /root/fluentbit/conf:/conf fluent/fluent-bit:0.12.9 /fluent-bit/bin/fluent-bit -c /conf/fluent-bit.conf
