The mem input plugin, gathers the information about the memory and swap usage of the running system every certain interval of time and reports the total amount of memory and the amount of free available.
In order to get memory and swap usage from your system, you can run the plugin from the command line or through the configuration file:
$ fluent-bit -i mem -t memory -o stdout -m '*'
