Metrics
Introduction
Each source's Metrics tab shows admit, queue, and reject proof for that source. Use it to answer whether the concurrency limit is doing work, which keys burned slots, and whether rejects were auth, overload, or another outcome.
Metrics is not billing. Request allowance, overage, and spend caps live on Billing.
What you see
- Outcomes: ok, overloaded, queue timeout, auth/IP rejects, upstream errors, and related statuses from the access log
- Admit vs queue: p50 / p99 queue wait, plus live queue depth from the source
- Top keys: by admitted traffic and by overload rejects (key labels only)
- Lock vs proxy: split between lock and proxy traffic
- Response cache: hit / miss / bypass when the response cache tagged the request
- Policy hits: requests tagged with a traffic policy name
History length matches your plan's log retention: Starter 1 day, Team 2 days, Business 7 days.
Team and budget rollups
The sources index and Capacity budget pages show last-24h admit/reject rates per source, with links into that source's Metrics tab.
Alerts and export
Configure email threshold alerts on the Metrics tab. You get an email when reject rate, queue p99, or overload count crosses your threshold. CSV export is available for the current range.
Metrics vs Billing
| Metrics | Billing | |
|---|---|---|
| Question | Did the concurrency limit do work? Who burned slots? | How much allowance did we use? |
| Data | Access-log rollups + live source snapshot | Billing usage records |
| Action | Diagnose 429s, tune concurrency, show proof | Manage plan, overage, spend caps |
