- 31. Production • Industry not ready • Limited web servers support • No UI • Spring Boot knowledge
- 32. Spring Boot Actuator • Helps manage and monitor applications when pushed to production • Accessible via HTTP, JMX or remote shell • You can't manage what you can't measure
- 33. Spring Boot Actuator • Series of endpoints to help manage your Spring application • Reads properties and spring beans and then returns a JSON view • Allows direct access to non functional application information without having to open an IDE or a command prompt
- 35. Spring Boot Actuator • /info • /health • /beans • /env • /dump • /metrics • /trace • /autoconfigurationreport • /shutdown
- 36. Spring Boot Actuator. Health Indicators DiskSpaceHealthIndicator Checks for low disk space. DataSourceHealthIndicator Checks that a connection to DataSource can be obtained. MongoHealthIndicator Checks that a Mongo database is up. RabbitHealthIndicator Checks that a Rabbit server is up. RedisHealthIndicator Checks that a Redis server is up.
