Metrics

The Metrics tab provides a metrics explorer scoped to the selected service. It displays all metrics associated with the service, including knowledge graph-generated asserts:* metrics for insights such as error ratios, anomaly thresholds, and predictions.

Data source and filters

The Metrics tab automatically configures:

Data source: your Grafana Cloud Prometheus instance.
Filters: pre-populated with service, namespace, and asserts_env labels matching the current service.

You can add additional label filters using the + label = value button.

Browse metrics

Metrics display in a grid of time-series previews. Use the controls at the top to:

Search: filter metrics by name. Type ? to ask the Grafana Assistant for help finding relevant metrics.
Sort by: order metrics by name or other criteria.
View: switch between Grid and Rows layout.

Each metric card shows:

The metric name
A small time-series preview
A Select button to explore the metric in more detail

Common metrics

Typical metrics you’ll find include:

asserts:alerts: active alert state for the service
asserts:error:ratio: calculated error ratio
asserts:error:ratio:prediction: predicted error ratio based on baselines
asserts:error:ratio:anomaly_upper_threshold: upper threshold for anomaly detection
asserts:error:ratio:service:stddev: standard deviation of the error ratio
