# Multiplayer observability
|
|
|
|
The control plane exposes `/metrics` with bounded operation and status labels.
|
|
The API latency metric is a cumulative histogram, so Prometheus can evaluate
|
|
the documented 250 ms p95 SLO with `histogram_quantile`. The optional
|
|
`deploy/observability/prometheus-rules.yaml` resource provides the API p95 and
|
|
5xx alerts for clusters running the Prometheus Operator.
|
|
|
|
Install the rule only after confirming that the `PrometheusRule` CRD and the
|
|
`cosmic-clash` namespace exist. The example `runbook_url` values are
|
|
placeholders and must be replaced with the operator's incident documentation
|
|
before production use.
|
|
|
|
This artifact intentionally does not claim coverage for regional RTT,
|
|
allocation/connect latency, tick headroom, durable-result success, or cost.
|
|
Those SLOs need additional server, allocator, and game-server series before
|
|
they can be alerted on safely; the current exporter cannot manufacture them.
