sudo required

npm start
/dev/mem: Permission denied

I suppose the system information library requires su rights. Maybe there is another lib/repo or solution to get this information? Or we need to check these rights on startup?

This can be reproduced on raspberry pi (3b+)

[Eirenliel]

Doesn't reproduce on Debian 9 for me. I think we need for the app to keep working fine even if fetching of any health data failed by any reason. Then we can investigate why it fails.

Does it work like this?

si.mem().catch(error => {return error})

[RobinTail]

In fact there is no promise rejection at this line. It's some kind of system error thrown into console @Eirenliel . I'm still trying to investigate

[RobinTail]

Also, it is not in si.mem() it is in si.cpu() @Eirenliel

[RobinTail]

Found the reason, @Eirenliel
This happen only since version 3.52.0 of systeminformation library. Here is the changelog:

Version 3.52.0: cpu() added physical cores, processors, socket type

[RobinTail]

I've made the bug report
sebhildebrandt/systeminformation#193

[RobinTail]

sebhildebrandt/systeminformation#193

need to be updated to v4.0.0, @Eirenliel
