KubeCon+CloudNativeCon EU 2024 - Noise monitoring

[jpkrohling]

During KubeCon NA 2023, I was talking to @codeboten about how noisy the booth crawl was, and we had an idea: spread Sound Level Meters around the sponsor showcase, collecting metrics and sending them in OTLP format to the backends of vendors. They can then showcase how that data looks on their solutions.

• [ ] Buy or build a Sound Level Meters
• [ ] Make it spit out OTLP
• [ ] Have a Collector that receives this data
• [ ] Recruit vendors
• [ ] Have a page somewhere listing all the vendors

would also be nice to do co2 monitoring

[codeboten]

im 100% interested in hacking on this :D

[djaglowski]

Wouldn't it be reasonably easy to also capture traces and logs from any application we write to collect the metrics?

[austinlparker]

Sure. I will point out that this isn't exactly an inexpensive endeavor -- off the shelf data loggers for this are probably gonna be a couple hundred dollars a pop, and they may only supply windows drivers (although who knows, I'd like to think they're just UART connections...).

A raspberry pi/arduino solution isn't gonna be that much less expensive I'd think, and would require assembly, but the bespoke option would at least give us some more flexibility... but then someone (or several someone's) would need to design and put it all together.

I would prooooobably go with some sort of SoC + co2 + acoustic sensor that a collector can run on, then write a custom receiver and arrow exporter? idk, also need to think about WiFi and such.

That's what I had in mind. The advantage of Raspberry Pi is that we can use a language we already support to instrument the application. The components aren't going to be that expensive if we focus on the sound level for now: it's the Pi's price (~70 EUR with a case?) plus ~20 EUR for the sensor. I bet @RichiH could even 3-D print some cool custom cases for us :-)

I can certainly get the value for one of those expensed by my employer, and if each one of the involved vendors can pay for their hardware, we can collaboratively work on the software.

Ditto, happy to help contribute to this. I think it would be super cool for the data to be available for anyone to use, including for demos on the exhibition floor.

[jpkrohling]

This was a good idea and I think we should be doing this, but I wasn't able to allocate time to build it :-(
