Grafana
An open-source observability interface connecting Prometheus, Loki, databases, and cloud services with dashboards, exploration, alerts, and sharing.
Why use it
Operators can watch concurrency, matchmaking queues, errors, latency, and event load together and compare before and after releases.
Where it fits
Use analytics, feedback, player support, and updates to fix issues and decide what to improve after launch.
What to check
Attractive charts are not effective alerts, and label cardinality and queries create cost; isolate public dashboards and data-source credentials rigorously.
