I am working on rolling out fluent-bit and currently make use of the tail plugin for my ruby based fluentd systems. When trying to run this on FreeBSD it get an error: $ fluent-bit -s 6000 -i tail -p path=/var/log/messages -o stdout Fluent Bit v1.7.2 * Copyright (C) 2019-2021 The Fluent Bit Authors * Copyright (C) 2015-2018 Treasure Data * Fluent Bit is a CNCF sub-project under the umbrella of Fluentd * https://fluentbit.io [2021/03/28 09:00:34] [ info] [engine] started (pid=50457) [2021/03/28 09:00:34] [ info] [storage] version=1.1.1, initializing...

Maybe it would be worthwile to set the CMake option FLB_IN_TAIL the this port to to False until this has been implemented upstream?

Any idea of the status of tail plugin in FreeBSD please? Installed fluent-bit 1.7.9 from packages, enabled tail plugin, we get this in logs every couple of seconds or so: [error] [/wrkdirs/usr/ports/sysutils/fluent-bit/work/.build/plugins/in_tail/CMakeFiles/flb-plugin-in_tail.dir/compiler_depend.ts:1104 errno=2] No such file or directory The plugin seems to work though, it reads files and sends the data, but I'm not sure what the error means or if it will still work later, on file rotation for example. (there's also the issue that fluent-bit dies if the `-d` flag is passed to it (daemon on), but I can report that separately)

Hi, the second issue with -d is possibly related to #255593.
