Description
I am looking at this dashboard panel and it query -- https://github.com/prometheus/node_exporter/blob/b52bf958f8e2d4ed1624b8122d08af4d12da9322/docs/node-mixin/dashboards/use.libsonnet#L229
for my cluster and i see negative values for 'CPU Utilisation'. Can someone please explain what utiliSation means and how is it different from utiliZation ? What does negative value signify here, if its valid ?
Node exporter version - 2.2.0

Start with the linked query in docs/node-mixin/dashboards/use.libsonnet#L229 and compare it with the reported dashboard behavior and node exporter version. Done means documenting what CPU Utilisation means, whether the spelling difference matters, and whether negative values are valid or indicate a problem.
