How can I get a breakdown of latency on each call?

The brakdown would ideally be Component / Avg Latency STT / x ms LLM / y ms TTS / z ms

Hi there! 👋 I wasn't able to find information on how to get the exact breakdown in the tabular format you requested with specific millisecond measurements. However, I can help you with several methods to access latency data for your Vapi calls! Here are the ways you can potentially get latency information for your calls: ### 1. Contact Vapi Support with Call IDs According to [Discord discussions](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336875140990111796), reaching out to Vapi support with specific call IDs can get you in-depth investigation. The support team can check logs and provide specific information regarding your calls, which likely includes latency data. ### 2. Use the "GET Get Call" API Endpoint The [Vapi API](https://docs.vapi.ai/api-reference/phone-numbers/list) includes a
GET Get Call
endpoint (
/api-reference/calls/get
) that might return detailed information about specific calls, potentially including latency data for the different components. ### 3. Capture Call Events with the Server SDK If you're using the server SDK, you can [implement real-time analytics](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1331285157088333955) by capturing call events. The SDK can trigger events when calls are initiated or completed, allowing you to track metrics including latency information. ### 4. Integrate with Langfuse for Telemetry Monitoring Vapi [integrates with Langfuse](https://docs.vapi.ai/providers/observability/langfuse), an open-source LLM engineering platform, for enhanced telemetry monitoring. This integration allows you to track, analyze, and visualize traces from AI interactions, which could help you monitor latency across components. ### 5. Review Vapi Configuration Settings
Examining your [Vapi configuration settings](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1332286268805087272) such as
silenceTimeoutSeconds
,
responseDelaySeconds
, and
llmRequestDelaySeconds
might provide insights into factors affecting latency. Is there a specific method from these options you'd like to explore further?

Hey Simon, as you already listed out how you want to break down the latency using the Turn latency and other logs available to you for a call. You can calculate it pretty simply by adding up the individual latencies. It will take some of your manual effort going through logs and identifying the right logs snippets.
