The Standard Output Filter plugin allows to print to the standard output the data received through the input plugin.
There are no parameters.
In order to start filtering records, you can run the filter from the command line or through the configuration file.
$ fluent-bit -i cpu -t cpu.local -F stdout -m '*' -o null -m '*'
In your main configuration file append the following FILTER sections:
[INPUT]Name cpuTag cpu.local[FILTER]Name stdoutMatch *[OUTPUT]Name nullMatch *
