Analytics

Analytics turns the current Search query into charts. Use it to move from an individual request log or trace to trends in usage, performance, cost, errors, and application behavior.

​

Open Analytics

1. Open Request Logs or Traces in the PromptLayer sidebar.
2. Set the date range and add any free-text or structured filters.
3. Switch from the Requests or Traces tab to Analytics.
4. Select Run query after changing the analytics query.

The table and Analytics tab use the same query. You can narrow the data first and then chart only the matching request logs or traces.

​

Request Analytics

Request analytics includes views for:

• Latency, request volume, tokens, and cost over time
• Requests by model, prompt, and status
• Response format, cached tokens, and reasoning tokens
• Provider, prompt, tag, and metadata cost breakdowns
• Common errors, metadata keys, output keys, and tools

Use metadata and tags to compare environments, customers, application versions, or other segments that matter to your application.

​

Trace Analytics

Trace analytics includes views for:

• End-to-end latency, including average, p50, p90, and p95
• Trace volume and status over time
• Models and tools used across traces
• Prompt templates and workflows used across traces
• Trace- and span-level filters

​

Interact with Charts

Many charts can update the current query. Depending on the chart, select a point, bar, or segment to add a filter, or drag across a time-series chart to narrow the date range. Use Undo to restore the previous analytics query.

​

Ask for an Analysis

Open the PromptLayer assistant and ask a question such as, “Create a graph of the most used prompts over the past week.” It can inspect request or trace analytics and create a chart from the relevant data.
