API metrics
See request rate, errors, latency, rate-limit hits and auth failures for each of your APIs, and how much history your plan keeps.
Every API you host on RestWard reports live metrics. Any member of your organization can see them, whatever their role.
Where to find them
- One API: open the API under APIs and pick the Metrics tab (next to Usage). A link to
/dashboard/apis/<id>?tab=metricsopens the tab directly. - All your APIs: the Dashboard has an API metrics · right now card. It shows the request rate, the error rate and the slowest p95 latency across your APIs for the last minute, and lists your busiest APIs. Each name links to that API's Metrics tab.
What the Metrics tab shows
| Chart | What it means |
|---|---|
| Requests per second | Every request your API served |
| Errors per second by status class | 4xx (client errors) and 5xx (server errors), drawn separately |
| Latency p50 / p95 / p99 | How long requests took inside the runtime, in milliseconds |
| Rate-limit hits per second | Requests refused with 429 because a key or the API was over its limit (see Rate limiting) |
| Auth failures per second by reason | Requests refused because the key or token was missing, invalid, expired and so on |
| License-locked refusals per second | Requests refused while your organization's license was locked |
Values are per-second rates averaged over a minute. Times are in UTC. The tab refreshes every 60 seconds while the browser tab is visible and pauses while it is hidden. Refresh reloads at once.
The metrics are measured at your API's runtime. They do not include requests that never reached it, and they never show other organizations' traffic or the platform's own capacity.
Time windows and your plan
Pick a window above the charts. Windows up to 7 days are live data with points every few minutes. Longer windows come from a daily summary: one point per UTC day, labelled Daily resolution.
| Plan | Windows you can open |
|---|---|
| Free | 1 h, 6 h, 24 h, 7 d |
| Trial and Starter | up to 30 d |
| Professional | up to 90 d |
| Enterprise | up to 395 d |
Windows beyond your plan are shown with a lock. Picking one explains why and links to Billing, where you can upgrade.
States you may see
- No traffic yet: the API has not served a request in this window. Send a request and wait a minute or two.
- Metrics are degraded: the metrics service did not answer. Charts marked Last known value show data from before the outage. Charts that say the service did not answer have no data. Your API itself keeps running.
- API not found: the API is not in your organization.
To send these metrics to your own monitoring system, see the metrics export settings (organization administrators, Professional plan and up).
