Service overview

The Service overview tab is the default view when you open a service. It displays the primary performance indicators using RED metrics, a duration heatmap, and outbound connection data.

Filters

The overview provides filters to refine the displayed data:

  • Runtime: select the runtime environment.
  • Request type: filter by inbound or outbound requests.
  • Source: select the span metrics source (for example, app_o11y_spanmetrics).
  • Operation: filter by specific operation or view all.
  • Group by / Group by label / Filter by: additional grouping and filtering options.

Panels

Latency

Displays the request latency over time as a time-series chart. Use the dropdown to switch between percentiles (P95, P99, AVG). Click Explore to open the query in Grafana Explore.

Error Ratio

Displays the error ratio as a percentage over time. A rising error ratio indicates an increase in failed requests relative to total requests.

Request Rate

Displays the number of requests per second the service handles over time.

Duration heatmap

Shows the distribution of request durations as a heatmap so you can identify latency outliers and bimodal distributions.

Outbound and databases

Displays latency and request data for outbound calls this service makes to other services and databases.

Comparison mode

Enable Comparison in the time controls to overlay data from a previous period (for example, the previous hour or day). This helps identify whether current performance deviates from typical patterns.

Next steps

  • Use Traces to investigate specific slow or failing requests.
  • Use Logs to correlate log entries with performance anomalies.
  • Add the service to RCA workbench for cross-service investigation.
