uin , in Tool for Monitoring Bandwidth in Real Time

So you want the available bandwidth to be monitored in “real time”, but you don’t want constant speed tests to happen. Then you mention a script doing a speed test.

You’re gonna have to choose: Either you run some kind of Speedtest on a regular basis, which will give you somewhat “real-time” results, or you don’t do it, and you don’t have real-time data as a result.

A very quick google search brought up this power shell script, that even formats the results for PRTG:

github.com/greiginsydney/New-OoklaSpeedTest.ps1

Yeah, I am a bit scatter brained today…lol. I am not sure what I want, but I will check out that github and see what I can do with that. Thank you!

So, a speed test can show bandwidth but so can a graph, when you see the flat line, you’ve hit your limit.

Use interface counter graphs to map out b/s and then you’ll be able to see where you’re actually maxing out. If you’ve hit a bandwidth limit on a connection but your graph is still spiky it’s not you it’s them.

uin ,

But if he wanted that historical data for, say, making sure an ISP delivers promised bandwidth, then unless he’s constantly maxing out the connection, the usage graph is going to be fairly useless.

pete ,

Yes, but doing a speed test while you’re using the link isn’t an accurate test, so it’s extremely difficult to be able to show bandwidth issues with anything other than a graph. If the ISP is not giving you your full bandwidth, you’ll flatline below the full bandwidth on the graph. If you are using half your link and do a speed test you will only get results for about half your link unless you drop all other traffic to do the speed test.

Thanks @DarraignTheSane for getting this going. I have high hopes 😊 if you need any mod support, please let me know.

I hope to see this community take off and take precedence over the one on lemmy.ml. I have been disappointed the past couple of days because most of the IT related subs seemed to be there and they have only been intermittently available and they seem to be having some trouble with federating their content to other instances. It’s not their fault, they are clearly being hugged much too tightly.

Also I know its just the nature of things to have competing subs, even on Reddit it happened. But I’d prefer not to have a split-brain situation with a sysadmin community nor do I want to be forced in to cross posting everything to both communities to increase my chances of engagement.

I share your sentiment at this point. I saw a thread where the one Lemmy dev / admin was talking about how they will not use Cloudflare or other major CDNs for lemmy.ml, and that they host on some minor provider because of privacy concerns. They said they were focusing on optimizing the Lemmy code instead to make it more efficient.

While I understand that and those concerns aren’t wrong, and certainly the code should always be written to be more efficient… at some point it’s going to meet the reality of millions of ex-reddit users hitting them, and they seem wholly unprepared for that. /u/Ruud seems to know what they’re doing with lemmy.world and building it to be able to scale.

Even though I’ve created the /c/Sysadmin sub on a handful of the larger Lemmy servers now, I’m thinking that lemmy.world will be my main going forward.

Hey @ruud , thanks for chiming in here on /c/Sysadmin! I’ve been trying to figure out how to best manage the Sysadmin communities I’ve setup across different Lemmy servers, but it’s looking like lemmy.world might be my new home server since it appears to have the best uptime and stability. 😉

Thank you! If you have multiple Sysadmin communities, maybe it’s an idea to close all of them but 1. Just mark them as ‘only moderator can post’ and pin a post telling people to subscribe to the 1 community.

This.

I initially agreed with you. I’d hate to see all of that communal knowledge lost.

Reading the other replies, I am not so sure. Do they deserve to continue capitalizing on other peoples knowledge? Yes and No. They did supply a service without which that collection would have had to be assembled somewhere else. But I don’t think they should be able to capitalize on it forever.

With the archive team and their efforts, I am less worried about “Wisdom of the Ancients” situation.

PixxlMan ,

I just hope the archives will be easily accessible and searchable, preferably without having to specifically leave the search engine to search them, otherwise the knowledge will still, in practice for most people, be inaccessible.

The data should be scraped and on Archive.org. I copied my posts and references, to share here.

Reddit will get my CCPA delete notice. Reddit is a failed experiment just like GeoCities, Yahoo, MySpace, Windows, Facebook, and Google. I don’t want or need them. The data I shared on these platforms is irrelevant because I am here. Ask away. I am the value, not them.

Nah, reddit doesn’t deserve that traffic.

Systems and software engineer here. I’m curious how the Lemmy project plans on scaling media uploads. It doesn’t seem feasible to host on an instance server. Even Reddit had a problem with media over the years and some subs to this day enforce offloading media to third party.

For now it’s 2GB. I hope we can use block storage soon. I use Wasabi for mastodon.world

huojtkeg ,

Just Postgres or Postgres + Pics? Could you give me the number for Postgres? I’m thinking in hosting my server but I have concerns abot scalability and costs in the future.

It seems a lot for little content. My experience tells me that Postgres is not going to scale well, some sort of NoSQL will be necessary.

ruud OP ,
@ruud@lemmy.world avatar

Why not? My mastodon DB is 200 GB, works fine.

huojtkeg ,

It depends on many things like the number of tables, the indexes, etc… but Postgres doesn’t work well above 1 TB. Anyway, it will take several years to reach that point. Someone will figure out a solution.

Thank you for the info. Do you have any link with the specs of your server, bandwidth, cpu/ram usage, statistics…? Anything that could help me to do the maths.
