Metrics

The Metrics page (under Monitoring) lets you explore any metric flowing into Ultraviolet and see how it moves over time.

Exploring a metric

• Pick a metric with type-ahead search — as you type you’ll see each metric’s kind and how many services and nodes report it, busiest first.
• Choose an aggregation (average, max, min, sum, count, or last value).
• Filter by service or node to focus in.
• Set the time window (15m to 7d) and optionally live-refresh it.

You get an instant value for the current window plus a chart of the trend. Counters, gauges, and histograms are all supported.

Where metrics come from

Metrics arrive alongside everything else — from your infrastructure and from any OpenTelemetry source you already run. There’s nothing extra to wire up beyond pointing existing exporters at Ultraviolet.

Already running Prometheus? Point its remote-write at Ultraviolet and every metric it scrapes shows up here — no exporters to replace. See Prometheus remote-write.

Alert on any metric

Any metric you can chart, you can alert on. Create a rule with the Metric value condition, pick the series and aggregation, set a threshold, and route it to your channels. See Alerts & notifications.
