HTTPServer

The HTTPServer is a standalone server for exposing a metric endpoint. A minimal example application for HTTPServer can be found in the examples directory.

HTTPServer server = HTTPServer.builder()
  .port(9400)
  .buildAndStart();

By default, HTTPServer binds to any IP address, you can change this with hostname() or inetAddress().

HTTPServer is configured with three endpoints:

/metrics for Prometheus scraping.
/-/healthy for simple health checks.
/ the default handler is a static HTML page.

The default handler can be changed with defaultHandler().

Authentication and HTTPS

authenticator() is for configuring authentication.
httpsConfigurator() is for configuring HTTPS.

You can find an example of authentication and SSL in the jmx_exporter.
