Analytics
Compare request volume, latency, errors, tokens, and cost across a project.
Open a project to see Overview. The page combines trace summaries with OTLP metric series for the selected period.
Select a period
Select Last 7 days, Last 30 days, or Last 90 days. The default period is 30 days. The project retention setting limits the available data.
Read the summary
The overview summarizes these values:
| Value | Definition |
|---|---|
| Requests | Trace count |
| Duration | Average duration and p95 latency |
| Error rate | Error count divided by request count |
| Tokens | Input tokens plus output tokens, with separate totals |
| Total cost | Sum of calculated model cost in USD |
The KPI cards compare the selected period with the immediately prior period of the same length. A lower p95 latency or error rate is a positive change.
A comparison appears only if the project retention contains two full periods. For example, a 30-day view needs at least 60 days of retention.
telemetry.dev calculates average and p95 duration. It does not calculate p50 duration.
Read time-series charts
The overview has three daily charts:
- Requests over time
- Cost over time
- Input and output tokens over time
telemetry.dev fills dates without data with zero values. This keeps each time axis continuous.
Compare groups
Use Group by on the request breakdown. You can select these dimensions:
- Model
- Provider
- Environment
- User
- Framework
The chart shows at most eight groups. It orders groups by total cost, then by request count.
Read OTLP metric series
The metric section shows one small chart for each ingested OTLP metric series. telemetry.dev selects the aggregation from the metric type:
| Metric type | Aggregation |
|---|---|
Duration histogram with unit s or ms |
p95 |
| Gauge | Average |
| Other metric type | Total |
For duration histograms, telemetry.dev rebuilds p95 from the explicit bounds and bucket counts. It uses linear interpolation inside the selected bucket.
The page uses hourly points for a period of 7 days or less. Longer periods use daily points.
The page can show 100 metric series. If a project has more series, it shows the most frequent series and a truncation notice.
If the period has no traces or metric series, select Go to Setup to connect an application.
