Thanks a lot mister
The problem is that mongodb need hypervisor support in version 5.0 and next updates, the old versions not and that is correct because the VirtualBox don´t give to its environment that property that mongodb needs.
So I have only question, the correct installation now to put running graylog is that?
mongodb 5.x or 6.x
debian 11, ubuntu 11
what will you do to make graylog installation in a enterprise production environment?
thanks a lot again mister.
Merry Xmas an a Happy New Year.
