Unfortunately Mongodb does not support my Proxmox CPU so I am not able to install Graylog on that server.
Any suggestions on which bare metal to use? Low wattage preferred. Have arround 8 Servers and 4 Clients.

Hey @toddhb

What I did was use Graylog 5.x with MongoDb 4.x then I added this line in Graylog configuration file.
`skip_preflight_checks = true`
For a lab its all good, I dont have any issues yet. MongoDb basically need the new hardware with AVX flag.

@ gsmith
Well, it would work, but from a security standpoint a cannot go this way. There are probably no updates for Mongodb available at the moment, and still if there are this will be discontinued soon. Even beeing in home lab this is no risk I am willing to take.

Hey @toddhb
I agree, To run MongoDb you will need the following CPU Flag = AVX
You can check on Linux with…
```auto
cat /proc/cpuinfo
```
Here is the docs…

@gsmith
Perfectly. The link provides a method to go with newer Mongo without AVX requirement. Thanks for it. Will try out later on.
