FluentBit pod memory settings

[rajagopr]

Had a question w.r.t setting memory limits required for FluentBit pods running as a DaemonSet.

Following the guidance provided here – https://docs.fluentbit.io/manual/administration/memory-management

So, if we impose a limit of 10MB for the input plugins and considering the worse case scenario of the output plugin consuming 20MB extra, as a minimum we need (30MB x 1.2) = 36MB.

The 20MB extra listed here for the output plugin, is this per output plugin?

Consider the following configuration:
1 input plugin – 10MB Mem_Buf_Limit
2 output plugins

Should one account for 40MB or 20MB considering that there are two output plugins?
Would this vary if the two output plugins are of the same type as opposed to different types.
