Add UPC temperature sensor monitoring

These sensors are part of their air quality measurements, which just happen to be very close to our server room.
Reduce frequency and print error

Rodrigo Arias Mallo	541110e90e	Add meteocat exporter Allows us to track ambient temperature changes and estimate the temperature delta between the server room and exterior temperature. We should be able to predict when we would need to stop the machines due to excesive temperature as summer approaches.	2025-05-23 16:23:27 +02:00
Rodrigo Arias Mallo	13e084f34f	Add custom nix-daemon exporter Allows us to see which derivations are being built in realtime. It is a bit of a hack, but it seems to work. We simply look at the environment of the child processes of nix-daemon (usually bash) and then look for the $name variable which should hold the current derivation being built. Needs root to be able to read the environ file of the different nix-daemon processes as they are owned by the nixbld* users.
