Metrics
One of the key signals of Observability is metrics. Find out how Dash0 allows you to quickly navigate through your metrics and use them in alerts and dashboards.
Supported Metric Types
Dash0 supports all standard OpenTelemetry metric types, with the exception of exponential histograms. The supported types include:
- Counter: Monotonically increasing values that track the occurrence of events
- Gauge: Values that can increase or decrease over time
- Histogram: Samples observations into configurable buckets
- Exponential Histogram: Samples observations into dynamically sized buckets
- Summary (Legacy): Similar to histograms but with client-side calculated quantiles
