M04 Q25 What are the two protocols you can use to access actuator endpoints?

Spring Boot Actuator supports two protocols:

• HTTP
• JMX

HTTP endpoints can be accessed by any HTTP Client, like CURL or Web Browser, by default following are enabled:

• /actuator/info
• /actuator/health

JMX allows you to access Actuator MBeans under org.springframework.boot group. You can access it with any tool that supports JMX protocol. One of the tool that you can use is JConsole which comes with JDK. You can access JMX:

• Locally by PID (enabled by default since Java SE 6)

• Remotely via Socket after enabling it with following Java VM flags (below example setup is simple but unsecure, do not use in production):

-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
