Windows server 2019 monitoring with agent how to do it

Have you tried with WSMAN? https://docs.centreon.com/pp/integrations/plugin-packs/procedures/operatingsystems-windows-wsman/

not yet. is it free  or licensed. any other option to monitor Windows and also the linux servers. 

Those connectors are part of our commercial editions.

Other option is to leverage NSClient e.g.
