HostTailer includes Fluent-bit logs

[sebastiangaiser]

Hey, we're using a HostTailer for sending Kubernetes cluster audit logs to Opensearch. The logs are getting parsed as json and everything works like like a charm. But unfortunately, the HostTailer Fluent-bit is producing some [ info] [input:tail:tail.0] inotify_fs_remove(): inode=11024910 watch_fd=20 messages.
Is there an option to exclude/remove these logs? Currently they get send to the stderr stream and I can simply exclude them via a grep filter in FluentD but that feels a bit odd.

Well I've just tested this out, and unfortunately sinceHostTailer logs to stdout adding:

annotations:
    fluentbit.io/exclude: "true"

would exclude the tailed logs themselves. (Deleting previous comments.)

Indeed, you're right. Maybe I was a bit to euphoric, yesterday

Maybe one of these way can help:

• reduce the log level to error with Log_Level error or -qq cli flag
• disable all logging altogether with Log_Level off (risky)

I guess we may want to configure this as a default behavior at https://github.com/kube-logging/logging-operator/blob/593d7193195c117e6800cd65b7fe81b4d18719e5/pkg/sdk/extensions/api/v1alpha1/filetailer.go. Shouldn't we?

Makes sense to me too

Currently this works as intended. With the telemetry controller the plan is to send host logs directly to the opentelemetry collector instead of writing them to stdout.
