# health

The .health() method for the SurrealDB Rust SDK checks that the server-side connection is able to run a health command (useful for readiness and liveness checks).

Runs a lightweight health check on the current session/connection. On success, the future resolves to `Ok(())`; otherwise you get a [`surrealdb::Error`](https://docs.rs/surrealdb/latest/surrealdb/struct.Error.html).

```rust title="Method Syntax"
db.health().await?
```

This is a simple way to assert the database is reachable and accepting commands after `connect` (or periodically in long-lived processes) without sending a full SurrealQL query.
