These are current graphs for lemmy.world (yet to add it to my Zabbix)

Diskspace:

du -sm *
960	pictrs
1273	postgres

Oh wow! 2GB already seems like a lot, especially since it looks like this instance has only been running for 10 days?

Dang dude, youre the man

I see you're using Hetzner. Those graphs don't really show what kind of CPU you're using. It's a 2 core i guess?

[–] ruud 2 points 1 year ago (1 children)

It was an 8 core. But the current server is a 32-core / 64 thread cpu.

For only 17k Users? Seems like a lot of CPU Usage. Damn.

[–] ruud 5 points 1 year ago (1 children)

That image was from when we had 8 cores. Now it's under 10% usage :-) So we have some spare.

[–] knF 1 points 1 year ago

It seems a high usage to me as well... what's the load? (from the uptime command) I'm puzzled as the disk and network are basically idle (very low usage) but the CPU is basically saturated...

Beside this THANK YOU FOR YOUR GREAT WORK!

it's most likely coming from postgres, db server tends to be the main resource hog.

Do you have any data redundancy? Like that if a hard drive dies? Or worse a hurricane takes out your whole server? What would happen to my newly created account?

[–] ruud 10 points 1 year ago (1 children)

It's on a VPS so any redundancy they use for storage, plus I make backups to a storagebox in a different datacenter

[–] SeeleLowe 2 points 1 year ago

Super cool!

[–] [email protected] 1 points 1 year ago

Wow, that's a lot of CPU usage
