Some system load graphs of last 24h

Can someone give me a hand. I see tons of posts of people talking about a picture in the OP but i see nothing. Am i doing something wrong? Is my connection bad? This seems to be happening quite a lot. For example the meme instance has almost zero pictures but i know just about every post should have one.

hmm yeah it was gone.. need to investigate..

It gets me every time seeing people using the product I build 🥹

Grafana is the most essential application in my job. I can use Notepad to code in a world without IDEs. I couldn't keep a damn thing running in the real world without Grafana. And I've been forced against my will to use alternatives in the past.
You worked on Grafana? Your product is awesome, I use it in my homelab for performance metrics
- Yes, I'm one of the designers 👍🏾
You work at Grafana?

I really enjoy your transparency and style of communication!

Comparing it to Spez and how Reddit became prior to the migration, this is such a refreshing change
- /u/Ruud is like /u/Spez but only if /u/Spez was actually cool.

It's been very snappy today, nice work! Is it all under Docker Compose with the node handling Nginx and Postgres as well?

Yes.
- I‘m really grateful for your and your colleagues‘ work. Thank you for letting us lemmy around here!!!
- Why did you guys roll back the UI to .7 from .10? I enjoyed some of the UI improvements, but I guess there were some bugs?
  Edit: I see its back to .10 maybe I had a browser tab open from before that I never refreshed

How far do you see lemmy.world capable of scaling to? One thing I've been noticing is the centralisation of Lemmy users on a few top servers, surely that cannot be healthy for federation? What are your thoughts on this?

How much is this costing you? Also who is your host? Is it on a virtual machine?

They have a dedicated server: https://lemmy.world/post/75556
- It's actually pretty funny to see him mention the growth (almost 12k users!) considering they've added, what, 50k or so users recently?
- Dedicated means local?
- My homies love dedicated servers
- Whoa, cool. Thanks. Only a matter of time until it gets overloaded though. Can't Lemmy run in a container service like Cloud Run or AWS App Runner?

Dang that's a lot of RAM

mastodon.world has the same server but with twice the RAM :-)
- What chassis? I’ve got 256GB in an R720 but only 32 cores here!

How much is that in beans?

How can I throw some bucks in your direction?

From the lemmy.world front page:

- Where in the frontpage can we see this?
  Edit: thank you all!

I can’t believe how fast you’ve managed to crowdsource and fix things on this instance. I haven’t seen many problems at all sharing comments and things.

Now that’s hot

As a server admin, I really hope it's not hot
- 2hot

Some of my usage is in this data and I like that.

This is awesome! As a systems engineer for my day job, I love seeing stuff like this!

I know that the RAM cache is just taking advantage of otherwise free RAM and will be dropped in favor of anything else, but it does stress me out a bit to see it "full" like that.

pretty gauges. the instance seems to be more stable/responsive today

I am not seeing them. Are they gone?

I notice your defederation list is completely depopulated today. Is that intentional?

No it's just moved to the bottom of the page apparently. I preferred it on the side. Maybe a tab would be better.
On 0.18.1-rc.10 the defederated instances are at the very bottom, not on the right hand side.
- OOoooooh! Thanks for the info.
  Also infinitely less clear and helpful...

THE DROP???!! >:O

Seriously! Talk about amazing optimization and debugging of the network service.

Who you hosting with?

They have a dedicated server: https://lemmy.world/post/75556
- I figured haha. I was wondering which company they used
  Whois shows Hetzner which answers my question :D

Thanks for all the hard work. It has been running so well all day!

So I‘m currently on planning to host an instance myself. This graph helped me quite a lot to get an idea what system resources are required.

Do you use any reverse proxy in front of it?

Lemmy world has a lot of users. So your instance initially will require a lot less resources ✌️
- Yeah I saw that. I‘m a big fan of minimalistic, yet super performant architectures and I‘m just trying to get a feeling on how I could solve this problem. I try to avoid any downtime, whenever possible
Nginx runs on the server , proxying to the lemmy docker containers
- That‘s what I had in mind. To run nginx on a seperate vps, so I can scale it easier. Run fediverse instances in the back, either all on one vps or on different vps. This way I could provide a hub while increase performance (due to compression and caching) and provide redundancy/load balancing if necessary.
  What‘s the typical traffic you experience? Peak (Gbit/s) and average/daily traffic (GB)

This is so cool to see. Thanks for posting! Lemmy.world has been super smooth today

calckey widgets

Damn that’s a huge chunk of (what looks like) a 64 core CPU there. Impressive!

It’s cool it can aggressively cache that much. Although I am perplexed why one would have a swap file configured in this case? What does it give you here? Sorry not trying to be an elitist or anything just have no idea what advantage you get!

I hate that radial graphs are so popular with *Grafana dashboards. Radial/pie charts are terrible representations for humans to interpret. I tend to try and convert them either to a stat with the line/time display or a bar chart. Humans are better judging linear relationships than radial.
