chemavxandClaude Opus 4.8 72395ecc0e monitoring: panel para el runner, Prometheus y Uptime Kuma
Los tres puntos ciegos que quedaban. El gitea-runner se dejó fuera del panel de
gitea a propósito, porque si cae se paran los builds pero Gitea sigue sirviendo
y pintar "gitea: Down" sería una falsa alarma; pero su caída es de las mudas y
merecía el suyo. Prometheus y Uptime Kuma se quedaron sin representar cuando el
panel "grafana" pasó a mirar sólo a su deployment en vez de a todo el namespace
monitoring (5d0078c).

Misma forma que los otros doce, con el selector acotado al workload concreto;
para Prometheus, que es un StatefulSet, la rama de deployment sale vacía y
resuelve la de statefulset. La fila de servicios estaba llena, así que se abre
una tercera y todo lo de debajo baja 4 filas de rejilla.

Verificado antes de escribirlo: las tres consultas dan 1 ahora y 0 con escasez
de réplicas simulada. Y después, los 15 estados a través del proxy de datasource
de Grafana, no consultando yo a Prometheus por otro lado.

Nota conocida, no un fallo: si kube-state-metrics cae, los 15 paneles se ponen
en rojo a la vez, porque todos dependen de sus métricas. Un tablero entero en
rojo hay que leerlo como "se ha caído el que mide", no como quince caídas.
