Thanks — I’m responding to your note that you’re on Build, you captured a 429 at 2026-03-07T23
3945.962655Z coming from STT, and your Agents → Your Agents → “my-agent” shows 0 concurrent sessions but you can’t find inference metrics in the dashboard. I’ll walk you step‑by‑step to the exact dashboard locations to check and give focused next steps to diagnose the 429.
Exactly where to find “Usage and limits” and inference concurrency
1. Sign in to the LiveKit Cloud dashboard and make sure you’ve selected the correct organization (top-left) if you have more than one.
2. In the left-hand menu, click Projects and select the project that contains “my-agent.”
3. In the project left-hand menu, click
Usage and limits (this item is inside the project-level navigation).
4. On the Usage and limits page:
◦ Look for a section or tab labeled
LiveKit Inference or
Inference.
◦ The inference widget shows
current concurrent inference usage and the plan limit (Build = 5 concurrent inference sessions).
◦ If a widget is present, expand any “view details” links on that widget to see recent spikes or real-time concurrency.
If you do not see “Usage and limits” or no Inference widget
• Confirm you have the right project selected (it’s common to be in a different project that shows metrics but not the inference quota for the agent you’re debugging).
• Confirm your user role has permission to view billing/usage. Users without owner/billing or quota-viewing roles may not see the Usage and limits page or inference widgets.
• The Inference widget may be grouped with other quota widgets or on a secondary tab—look for tabs/filters on the Usage page.
• From the left menu you can also open
Billing — some accounts surface plan and quota details there.
Quick checklist to capture if the widget is missing
• Which top-left organization and project are selected?
• Which left-menu items do you see under the project (Overview, Sessions, Agents, Logs, Billing, etc.)?
• A short redacted screenshot of the project left menu + Usage page helps me confirm what you’re seeing.
Why you may still get a 429 even though “my-agent” shows 0 sessions
• Agent sessions in Agents → Your Agents show long-lived agent connections; inference concurrency counts active model calls (STT/LLM/TTS). Short-lived or overlapping inference requests (retries, parallel STT+LLM+TTS steps, or transient initialization) can exhaust the Build plan’s 5 concurrent inference slots and return 429s.
• The STT request you logged at 2026-03-07T23
3945.962655Z could have overlapped with other transient requests or retries.
Immediate diagnostic steps to correlate the 429
1. From your app/agent logs, find entries around 2026-03-07T23
3945.962655Z:
◦ Client-side: STT start/stop, retries, connection attempts.
◦ Agent-side: any restarts, initialization logs, or error messages.
1. From agent logs (Agent Observability / agent deployment logs), search that timestamp for STT / inference-related calls. Use the agent logs guide if needed:
https://livekit.io/field-guides/guide/agent-logs
2. Note whether multiple STT/LLM/TTS requests were started close together. Even brief overlaps count toward concurrency.
3. If you see repeated retries or crash loops, add exponential backoff on retries and stop any restarting agents while you investigate.
Short-term mitigations
• Add or increase exponential backoff on client retries to avoid retry storms.
• Limit parallel STT clients temporarily (queue requests instead of starting many at once).
• If you confirm frequent concurrency exhaustion, consider upgrading from Build (5) to Ship (20) or Scale (50).
If you want, I can continue helping — please share any one of the following:
• A redacted screenshot of your project Usage and limits page (or the left-hand project menu if Usage isn’t visible).
• A short log excerpt (client or agent) around 2026-03-07T23
3945.962655Z showing the STT request/response (remove any secrets).
• The exact project name shown in the dashboard so I can guide you to the correct project-level views.
Tell me which of those you can share and I’ll walk through the logs and dashboard with you step by step.
