# Health

The health page: status, the ephemeral sweep and every link with its counters.

One JSON document on the health address. It answers 200 while the server serves and carries each link's counters.

## Scope

The `/health` route of the running server.

**Terminal**

```bash
curl -s http://127.0.0.1:7601/health
```


## The details

The document has `status`, `message`, `ephemeral_sweep` and `links`. Each link is keyed by its id.

- `links_opened`: Opens that succeeded on this link since the server started.
- `refused`: Opens the peer refused by name. The last refusal is kept as last_refusal.
- `dial_refused`: Dials the operating system refused before any open. The dial is retried.
- `crossed`: Records that crossed the link.
- `resumed_from`: For each exported subject, the position the peer resumed from after the last open.
