El Nino Watch
Lists every data source with its state: ok, stale, empty, error, needs config or pending, plus when it last worked and how old its newest data is.
Data and trust
Every number in the app comes from a named source (a "collector"). Each run of each collector is recorded, whether it works or not. The Sources page shows the result.
"Fetch ok" and "data fresh" are different things: a website can answer normally while serving data that is weeks old. That is why "stale" is shown separately from "ok".
| State | Meaning | What to do |
|---|---|---|
| ok | The last run worked and the newest data is within its maximum age. | Nothing. |
| stale | The fetch works, but the newest data is older than its maximum age. | Use the values with care; check the date shown. |
| empty | The source answered but returned nothing (for example no event in the area). | Often normal for alert feeds; not an error. |
| error | The last run failed (site down, network, or the format changed). | Values shown are from the last good run; check the date. |
| needs config | The source needs a key or setting that is not configured (optional paid sources). | Ignore unless you want that source. |
| pending | Not run yet since the app started. | Wait a few minutes. |
