Any application monitoring solution should maintain an open design, build upon proven technologies, be accessible, and require a low learning curve. The end goal is simple: provide teams with the ability to identify issues or unexpected behavior within minutes, if not seconds. The ELK Stack meets these expectations and more. In this Refcard, you'll cover the basic components of the ELK Stack, how it maps to a log analysis workflow, and step-by-step instructions for installation, configuration, and reporting.

Performance in any cloud-distributed application is key to successful user experience. Thus, having a deep understanding of how to measure performance and what metric IO pattern to use is quite important. In this article, we will cover the following:
There’s no one-size-fits-all approach regarding application monitoring, especially for companies using applications in various cloud environments. Companies are rapidly investing in microservices, mobile apps, data science programs, data ops, etc. Subsequently, they’re also integrating monitoring tools to improve domain-centric monitoring abilities.
AIOps tools help streamline the use of monitoring applications. It allows companies that need high application services to efficiently manage the complexities of IT workflows and monitoring tools. AIOps extends machine learning and automation abilities to IT operations. These robust technologies aim to detect vulnerabilities and issues to resolve them, determine operational trends, and simplify the remediation of the problems that affect their applications’ performance and availability.
In the past, code and infrastructure were handled by completely separate organizations. Developers wrote code, while IT set up servers. Developers fixed bugs, while IT handled infrastructure maintenance. However, with the trend towards DevOps and the increased availability of Platform-as-a-Service (PaaS), there is an increasing overlap between Dev and IT. For developers, this can mean taking care of infrastructure, a task that is quite different from standard app dev.
As a full-stack developer, I've been pushed to handle more and more infrastructure-related responsibilities, including monitoring production applications. We just went live for HP Foundation at https://www.life-global.org with our Next.js-based learning management system. As a dev team lead, I have been researching how to best support and maintain the application through metrics.
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.
