Because of this, **FastAPI** itself provides an alternative API documentation (using ReDoc), which you can access at <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>:

to generate a trusted root certificate, an intermediate certificate, and a server certificate.
We use `certificateAuthority(int)` to create certificates that can sign other certificates. The
int specifies how many intermediate certificates are allowed beneath it in the chain.

```java
HeldCertificate rootCertificate = new HeldCertificate.Builder()
    .certificateAuthority(1)
    .build();

  /**
   * Creates a new instance with {@code null} as its detail message and the given cause. Prefer to
   * provide a non-nullable {@code cause}, as many users expect to find one.

In many cases you might already know the answer for those questions. 🤓

This is the preferred method for any new dashboards.

## Legacy Dashboards

Many of our older dashboards are manually created in the UI and exported as JSON and checked in.

## Generation

## Benchmarks and speed

When you check the benchmarks, it is common to see several tools of different types compared as equivalent.

Specifically, to see Uvicorn, Starlette and FastAPI compared together (among many other tools).

The simpler the problem solved by the tool, the better performance it will get. And most of the benchmarks don't test the additional features provided by the tool.

The hierarchy is like:

/**
 * Covers basic sanity checks for the entire package.

public class PackageSanityTests extends AbstractPackageSanityTests {
  public PackageSanityTests() {
    publicApiOnly(); // Many package-private classes are tested through the public API.
    setDefault(DiscreteDomain.class, DiscreteDomain.integers());
  }

	// Delay is the sleep multiplier.
	Delay float64 `json:"delay"`

	// Sleep always or based on incoming S3 requests.
	IdleMode int32 // 0 => on, 1 => off

	// Alert upon this many excess object versions
	ExcessVersions int64 // 100

	// Alert upon this many excess sub-folders per folder in an erasure set.
	ExcessFolders int64 // 50000

	// MaxWait is maximum wait time between operations
	MaxWait time.Duration
