36. Monitoring and management over HTTP

If you are developing a Spring MVC application, Spring Boot Actuator will auto-configure all non-sensitive endpoints to be exposed over HTTP. The default convention is to use the id of the endpoint as the URL path. For example, health is exposed as /health.

36.1 Exposing sensitive endpoints

If you use “Spring Security” sensitive endpoints will be exposed over HTTP, but also protected. By default “basic” authentication will be used with the username user and a generated password (which is printed on the console when the application starts).


Generated passwords are logged as the application starts. Search for “Using default security password”.

You can use Spring properties to change the username and password and to change the security role required to access the endpoints. For example, you might set the following in your application.properties:


36.2 Customizing the management server context path

Sometimes it is useful to group all management endpoints under a single path. For example, your application might already use /info for another purpose. You can use the management.contextPath property to set a prefix for your management endpoint:


The application.properties example above will change the endpoint from /{id} to /manage/{id} (e.g. /manage/info).

36.3 Customizing the management server port

Exposing management endpoints using the default HTTP port is a sensible choice for cloud based deployments. If, however, your application runs inside your own data center you may prefer to expose endpoints using a different HTTP port.

The management.port property can be used to change the HTTP port.


Since your management port is often protected by a firewall, and not exposed to the public you might not need security on the management endpoints, even if your main application is secure. In that case you will have Spring Security on the classpath, and you can disable management security like this:


(If you don’t have Spring Security on the classpath then there is no need to explicitly disable the management security in this way, and it might even break the application.)

36.4 Customizing the management server address

You can customize the address that the management endpoints are available on by setting the management.address property. This can be useful if you want to listen only on an internal or ops-facing network, or to only listen for connections from localhost.


You can only listen on a different address if the port is different to the main server port.

Here is an example application.properties that will not allow remote management connections:


36.5 Disabling HTTP endpoints

If you don’t want to expose endpoints over HTTP you can set the management port to -1:
