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

After some digging it looks like their tail implementation is only supported on Linux/OSX and Windows:
Filing this ticket to see if it would be possible to get a patch together to add support for the tail plugin.
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.
(In reply to Christopher Beppler from comment #3)
I've seen that ticket, but I wasn't sure what to make of it. It starts, but not as daemon. I'll add my comments there.
Trying to enable the loki plugin i get a similar error:
