Monitoring production is an important part of a software service provider. Many companies providing monitoring systems for maintaining the production environment. Spring Boot comes with different awesome modules that developers can easily configure and maintain development and production environments with. The actuator module provides production-ready features by which we can easily maintain the production environment. The actuator exposes JMX and HTTP endpoints.
Features
- Endpoints: Spring Boot Actuator provides some default endpoints by which we can access application information. We can also monitor the production environment with those endpoints. Endpoints can also be accessed by third-party monitoring tools.
- Metrics: We can access OS and JVM related information using spring boot actuator endpoints. This is very useful for runtime environment. Spring boot actuator provides this feature by integrating with micrometer application monitoring.
- Audit: Spring Boot Actuator publishes events to
AuditEventRepository. Spring security by default publishes “authentication success,” “failure,” and “access denied” exceptions. This is a very useful feature for reporting and authentication failures. Auditing can be enabled by AuditEventRepository. By default, spring-boot provides InMemoryAuditEventRepository for auditing which has limited capabilities. - HTTP Tracing: Spring boot actuator also provides an HTTP tracing facility. If you want to use it you have to include web endpoint. Http tracing provides the information about request-response exchange.
Important Endpoints
Spring Boot Actuator provides the listed HTTP and JMX endpoint. We will discuss in detail later part of this article.
