Custom Monitoring Endpoints

Custom monitoring endpoints are user-defined HTTP endpoints in applications that expose health, performance, and business metrics for monitoring purposes. They allow developers to instrument their code to provide real-time insights into application state, such as uptime, response times, error rates, or custom business logic. This enables proactive monitoring, alerting, and troubleshooting in production environments.

Also known as: Health Endpoints, Custom Metrics Endpoints, Application Monitoring Endpoints, Probes, Status Endpoints

Why learn Custom Monitoring Endpoints?

Developers should implement custom monitoring endpoints when building applications that require observability beyond basic server health, such as microservices, APIs, or distributed systems where specific metrics are critical for operations. They are essential for detecting issues early, ensuring service-level agreements (SLAs), and providing granular visibility into application performance, especially in cloud-native or containerized deployments where traditional monitoring tools may not capture custom logic.
