Hot water heated by this cluster · last 24 h

0.00 litres of 38 °C shower water · last 24 h
— W of useful heat right now

Measured CPU load × 12 W/core, with 85 % of server heat captured for hot water — the Leafcloud model — over the last 24 hours. History lives in a ConfigMap, so it survives pod restarts and hibernation. An estimate, honestly labelled.

Ask the cluster · an LLM whose heat you can see

Answers come from a small language model (Qwen2.5-0.5B via llama.cpp) running on the worker nodes above — no external API. Its CPU heat is captured for hot water like everything else here, and each answer is billed in millilitres.

Burns CPU in the app pods for 60 s. The HPA scales replicas at 60 % CPU; push far enough and the cluster autoscaler asks Nova for a new node. Watch the node cards and events above.
