Sentinel
Not another dashboard — a to-do list for your cluster.

Prometheus and Grafana tell you what is happening. Sentinel tells you what to do. It runs inside your cluster, executes a battery of health checks — pods, nodes, PVCs, certificates, GitOps apps, backups, storage, image hygiene — and turns the results into a short, opinionated list of maintenance items.
Problems become tickets, not pages
Critical events go to Slack. Recurring pod-log errors are fingerprinted, summarised, and opened as issues against the right repository — with enough context that whoever picks them up can start fixing instead of investigating. A stability window keeps deploy-time restarts from becoming noise.
Maintenance on rails
When a Helm chart you run has a new release, Sentinel opens a one-line merge request against your infrastructure repo with a summarised release-notes brief, so staying current is a review-and-merge instead of a research afternoon. There's a resource browser with per-pod log streaming for the moments you do need to dig, and built-in secret sealing for the moments you need to ship configuration safely.
