Grafana
A query and dashboard interface over metrics and logs.
The problem it solves
A query and dashboard interface over metrics and logs.
Technical rationale
Grafana brings metrics and logs into one query, which is where diagnosis stops being a jump between tools with different clocks. It is served outside the cluster and through the tunnel on purpose: a dashboard that depends on the infrastructure it watches is unavailable at the one moment it is needed.
How I have used it
It reads Prometheus and Loki and is served outside the cluster, because a dashboard that depends on the cluster is unavailable when it is needed.
