[why2025-orga] Sysadmin: more data for stats.why2025.org please

[Hugo Blok]

Hi everyone,

We have a statistics page for the event (stats.why2025.org, running 
Grafana) that currently only has ticket and merch sale statistics on it.

At Team:Sysadmin we really love numbers, and would like to add many more 
numbers to the stats page. For example, bandwith used, the power voltage 
and frequency. Or something completely different, such as the amount of 
Mate bottles sold.

If you have any interesting data to share please send us a message. If 
it's related to camp and you can assign a number to it we're interested.

Data can be added to Grafana using MQTT (websockets or mqtt://). If the 
data cannot be provided via MQTT, send us an email anyway and we'll 
figure something out.

We can be reached at:
sysadmin at why2025.org

Kind regards,
Splodin (Hugo)
Team:Sysadmin
