That is [normally](https://discuss.elastic.co/t/one-or-more-required-cgroup-files-not-found-of-cgroup/163054/2) a DEBUG message, not an ERROR. It should not stop anything working.

That will persist the in-memory sincedb to a file called NULL in logstash's working directory. On Windows you should use "NUL", on UNIX use "/dev/null".
