Actuators in Spring Boot

About Actuators/health/info/env /metrics /shutdown

Example endpoints

/health/info/env /metrics /trace/auditevents/autoconfig/shutdown…

Built in JMX / HTTP endpoints to help you monitor and manage your application

Potentially sensitive information available

Looking ahead

21

What’s ahead for Spring Boot 2.0? Spring Boot 2.0 will support Spring WebFlux and Spring Framework 5.0 Autoconfiguration for full-stack reactive applications Support for Java 9 Support for Java EE 8 (e.g. Servlet 4 and Bean Validation) Support major generation updates of Spring projects• e.g. Spring Integration 5.0, Spring Session 2.0, etc

Pluggable reactive runtimes - Apache Tomcat, Reactor Netty, Jetty, Undertow*

22

What’s ahead for Spring Boot & Pivotal Cloud Foundry

Working on the next set of Spring Boot Actuators!

/heapdump/dump/trace

23

What’s ahead for Spring Boot & Pivotal Cloud Foundry? MOAR Actuators! Like, all of them except /shutdown and /logfile Piping Spring Boot Actuator custom /metrics into PCF Metrics UX Considering reactive Actuator endpoints Considering Microservices Dashboard

What else? If you use Boot & Pivotal Cloud Foundry, we’d like to hear from you!

Spring and Pivotal Cloud Foundry: Spring Cloud Services

What is Spring Cloud Services (SCS)?• 100% PCF managed NetflixOSS Eureka, Hystrix and Pivotal Config server

• Now in public beta on Pivotal Web Services (PWS)

Things we’re considering for SCS 1.3 + • Config Server composite backends (Vault & Git)

• Spring Cloud Data Flow support

• Support PCF surgical routing, C2C networking in SCS Connector client

• Service Registry sharing across more than CF Orgs/Spaces, arbitrary linking

• Evolve config server into a more self-contained config management product

• Service registry dynamic routing (pair Eureka instances with Zuul instances)

25

PCF Metrics and Spring Cloud Sleuth: Trace Explorer

Detect in logs that Zipkin trace output is present

Examine in PCF Metrics time series user interface• Will find all logs with that trace ID

• Which services did it touch

• Will give span (timing)

• Call hierarchy
