Polling Based Monitoring
Polling based monitoring is a technique where a monitoring system periodically queries or 'polls' target systems, services, or applications to collect metrics, check status, and detect issues. It involves sending requests at regular intervals (e.g., every 30 seconds) to gather data like response times, resource usage, or availability. This approach is widely used in IT infrastructure, network management, and application performance monitoring to ensure systems are operational and performing as expected.
Developers should learn and use polling based monitoring when they need to proactively track the health and performance of distributed systems, servers, APIs, or network devices in environments where real-time, event-driven monitoring isn't feasible or necessary. It's particularly useful for legacy systems that don't support push-based notifications, for compliance with scheduled checks, or in scenarios where simplicity and control over data collection intervals are priorities, such as in basic uptime monitoring or resource utilization tracking.
