Hello,
Are you refering to my Graylog server? If so that doesnt make a difference to nxlog on my Hyper-V server. Hyper-V server is not a VM its hardware. As for our VM’s with NXlog on them they are the same stats. Most, if not all VM’s have 4CPU’s and 4 GB RAM.
We have all three (mostly 2019) and they all run the same stats as shown above.
No you dont have to adjust that. NXlog basiclly using 6.5 MB of memory. I wouldnt worry to much, maybe if it was 20 years ago thou 
Hope that helps.
