Added some new Mastodon monitoring infrastructure for discuss.systems.

Sure, every good #MastoAdmin has a cool Grafana dashboard, but we're going a bit more old school here...

@dan let's get a steam powered cpu monitor!

Dan Ports

@chouti Really embracing cloud computing there!

Dan Ports

@mike Yes! I'll write something up. The short version is that it's an ESP32 controlling a 100V supply via PWM with a MOSFET, and a simple shell script sending CPU utilization to @esphome via MQTT.

Mike | Raymond Tec

@dan @esphome I'm assuming that to connect the ESP32, PWM, and MOSFET to the rad looking steam gauge I will need a wand and cauldron?

Seriously though, super cool project and I'd love to see any write-up, photos, or videos you can make!

Thanks for sharing this!!

Dan Cross

@mike @dan @esphome copper wire was sacrificed as an offering to the dark gods of nondeterminism and performance, while the incantations we're chanted. "Volt-ohm, ampere gaussae."

Nick

@dan

That's a nice gauge you got there mister. ๐Ÿคฉ

AI6YR

@dan Oooh, I have a bunch of analog meters, I should wire them up to do that.

Dan Ports

@ai6yr Then you can monitor a whole cluster!

Hazel Weakly

@dan hey @quintessence I know what @nova wants for her birthday ๐Ÿ‘€

Dan Ports

@hazelweakly @quintessence @nova Hey, I'm in Seattle and I've got extras of all the parts you need to make a MQTT to 100V exporter... just add antique meter...

Marc Jacobs

@dan Now I want to find my old exposure meter with the CdSe sensor.

This is just brilliant.

Dan Ports

This is an antique Weston voltmeter that I accidentally* bought at auction from a telephone museum that was closing down a few years ago. (I also got some cool historical transatlantic cable segments!)

It draws a surprising amount of current for a voltmeter, so the circuit that's controlling uses far more power than I was anticipating.

*ok, it wasn't _really_ an accident! I certainly wasn't complaining...

Dev

@dan imagining a sitch where that uses more power than discuss.systems

Az

@Ex_spurt @dan holy shit i think i need something like this for my setup (i actually have a plan for something in mid-2023 using a flight sim radio aircraft panel ๐Ÿ‘€)

Dan Ports

@anttipeltola The latest patent date on that meter is 1901, I think that makes it Web 0.1!

Zee

@dan thatโ€™s sexy AF ๐Ÿ‘๐Ÿผ

AZcoigreach

@dan i'm writing some code to display stats on my LED board in my office.

Rai

@dan nice! needs to show an exponential moving average so it changes continuously :3

Rodrigo

@agentydragon @dan this ^

Also, maybe the minute load averages from /proc/loadavg are more useful than instant CPU usage.

Dan

@dan@discuss.systems cannot express how much I fucking adore this

Sam

@dan

That beats a dashboard any day! Might make writing my system Performance reports more interesting ๐Ÿ˜†

Derek Brauders

@dan almost #steampunk in presence? This might even start a trend in computer display / hardware (which might be pretty nice...)

Looks great!

Zixian Cai

@dan what will the metre read when the CPU usage hits 100% ๐Ÿค”

David "Dave" Treloar

@dan

Go techno retro like Loki style, then you get the added bonus of Miss Minutes :D

Az

@dan hey @shmouflon i think we need some this for ScorpInc

Shmouf

@az multiple gauges like an old fashioned weather station/barometer for demonic activity, user traffic and parking inspector saturation?

Az

@shmouflon hmmm. now i'm wondering if you have a good cheap SDR setup you could tune into their radio frequencies? ๐Ÿ‘€

Az

@shmouflon like, not for broadcast but just measuring the amount of traffic on their frequencies.

Shmouf

@az but also sometimes for broadcast as their new supervisor Guy Incognito directs them to a lower level parking garage that isnโ€™t a trap?

David

@dan Iโ€™d love to see a write-up of what you didโ€ฆI want one ๐Ÿ˜‚

scetron

@dan that is really cool. Iโ€™m going to have to accidentally win an auction.

๐Ÿ‡ธโ€Š๐Ÿ‡ญโ€Š๐Ÿ‡ฎโ€Š๐Ÿ‡ณโ€Š๐Ÿ‡ฒโ€Š๐Ÿ‡ฆโ€Š๐Ÿ‡ฎ

@dan given how ActivityPub functions, setting up a CPU usage meter that caps at 80 seems pretty optimistic :D

shory

@dan that is absolutely amazing

Quinn Wilton

@dan I am actually in awe. This is incredible, Dan

John Regehr

@dan not the important part, but very strong usage of the label printer

Brandon Rohrer

@dan Iโ€™m all in on this version of our Steampunk future

Lynn Grant

@dan Very cool. Back in the day, the IBM System 370/168 had an analog CPU utilization meter on its monster 3066 operator console. But it wasnโ€™t nearly as fancy and pretty as the one you have.

Thorne Lawler

@dan I can see a case-mod now: What a PC really needs is a boiler.

crashmat

@dan i want รพis but for รพe entire worldโ€™s compute power

velacy

@dan I feel like I've never witnessed something this classy before.

Marvin Hamon

@dan that is excellent. I like all kinds of old electrical equipment and reuse.

tonygilkerson

@dan much fun! I put this on my list of projects todo
