Metrics

Explore → Metrics lists every metric your services sent in the time range, next to a graph of the one you pick. The page URL holds the metric, filters, aggregation, grouping, chart type, and time range, so you can share a link to the same graph.

​

Pick a metric

The list on the left groups metrics by the part of the name before the first dot, such as http or process. Cloud provider metrics, such as CloudWatch, are listed after your own. Search metrics matches names, descriptions, units, and attribute keys. When you open the page without a metric, it shows the first one in the list. The header shows the metric’s name, its kind (Gauge, Sum, Histogram, Exp. histogram, or Summary), its unit, which services report it, and how many attributes it has.

​

Filter

The search bar filters by resource attributes and data point attributes. Pick an attribute, = or !=, and a value. A graph can have up to 50 filters.

​

Aggregation

Aggregation sets how data points combine in each time step: Histograms open on 95th percentile and summaries on Average. Count counts data points and has no unit.

​

Group by

Group by splits the graph into one series per value of an attribute. Each option shows whether it is a data point or resource attribute and how many values it has. Choose No grouping for one series.

​

Chart

Switch between Lines and Bars. The heading names the aggregation, metric, and grouping, and shows the series count and time step. Drag across the graph to zoom into that window. The time picker works as in Logs. Below the graph, a table lists each series with its Avg, Max, and Last value. Click a series to hide or show it.

​

Use the graph elsewhere

• Add to dashboard adds the graph as a widget to an existing dashboard or a New dashboard. See Dashboards.
• Create alert opens a new alert with this metric, its filters, and its grouping filled in. See Alerts.
