[Q&A] How to disable fluentd posting it's internal logs to remote server

[viralmutant]

What is a problem?

I have a fluent-package 5.0.4 fluentd 1.16.5 (95d130aaa44fc09b14a4e9686ee8018253185fc5) configuration that monitors and posts logs to a remote server for various log files.

However, I see that the internal WARN logs from Fluentd are also being POSTed to the server. The logs reside in /var/log/fluent/fluentd.log
Logs like the following appear on the remote:

'failed to flush buffer'
'retry succeeded'
'threshold' etc.

Is this the default behavior of Fluentd to POST it's internal logs to remote server ?
How do I disable this ?
