Manish Mishra presented on application performance monitoring with Springboot Actuator. He discussed what application performance monitoring is, why it is important, and how Springboot Actuator can be used to integrate performance monitoring into applications. Springboot Actuator exposes operational information and metrics through HTTP endpoints. It was demonstrated how to add Actuator dependencies, enable endpoints, integrate with InfluxDB for backend storage, and view metrics in Chronograf dashboards.

6. Springboot Actuator
● The library which brings metrics to live
● We can gather metrics, health, and other operational information which are
ready for production
● Actuator is mainly used to expose operational information about the running
application — health, metrics, info, dump, env, etc.
● It uses HTTP endpoints or JMX beans to enable us to interact with it.

7. Springboot Actuator
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
We can start by adding the below dependencies to our build

8. Enabling Endpoints
● Some endpoints are provided by default but if we want to expose a specific
endpoint, we can configure it.
● Here is a link of the documentation pointing to it
https://docs.spring.io/spring-boot/docs/current/reference/html/actuator.ht
ml#actuator.endpoints.enabling

9. Actuator Integrations
● Spring Boot Actuator provides dependency management and
auto-configuration for Micrometer, an application metrics facade that
supports numerous monitoring systems, including: Influx. We can add the
following dependencies to our application to enable the integrations.
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-core</artifactId>
</dependency>

10. Configuring Influx
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-influx</artifactId>
<version>${micrometer.version}</version>
</dependency>
We are required to the following in order to use influx as our integration with
backend database.

11. Configuring Influx DB

12. Creating a Metric: A Small Demo
● Defining the business need
● Adding meter to Code
● Adding query to create a dashboard in chronograf

13. Chronograf: The Dashboard
We can install and configure the influx source and create a dashboard using the
link below:
