Spring Boot Actuator Server Config

Known Vulnerabilities Maven Central

This project allows to configure the Spring Boot management connector separately from the default connector.

Versions

Multiple branches are maintained to support multiple Spring Boot versions. The following tables show the relation between the Spring Boot version and the Spring Boot Actuator Server Config version.

Spring Boot Spring Boot Actuator Server Config Branch
1.5.x 1.0.x 1.0.x
2.0.x 2.0.x 2.0.x
2.1.x 2.1.x master

Installation

  1. Add the following Maven dependency:
<dependency>
    <groupId>com.github.timpeeters</groupId>
    <artifactId>spring-boot-actuator-server-config</artifactId>
    <version>X.X.X</version>
</dependency>

Thread pool example

Spring Boot allows to configure the web container to listen on multiple ports. Using the server.port property, we can configure the port for the public traffic. Using the management.port, we can configure the port for the management (Actuator) traffic. It might make sense to use a big thread pool for the public traffic while using a smaller thread pool for management traffic. By default Spring Boot will apply all the settings of the default port to the management port as well. Using spring-boot-actuator-server-config, we can configure the management port independently.

Below we leverage the following properties to configure the management thread pool: management.server.tomcat.max-threads and management.server.tomcat.min-spare-threads.

management.server.port=8081
management.server.tomcat.max-threads=5
management.server.tomcat.min-spare-threads=${management.tomcat.max-threads}

server.port=8080
server.tomcat.max-threads=200
server.tomcat.min-spare-threads=${server.tomcat.max-threads}
