What is Prometheus?
Prometheus is an open-source monitoring and alerting system that is often used in DevOps environments.
📌It is designed to collect metrics from various sources, such as systems and applications, and make them available for analysis and visualization.
📌Prometheus uses a pull-based model for collecting metrics, which means that it periodically queries the metrics endpoint of a target system rather than the system sending metrics to Prometheus.
📌Prometheus also includes an alerting engine that can trigger alerts based on the values of the metrics it collects. This makes it a powerful tool for monitoring the performance and availability of distributed systems, and for detecting and responding to issues quickly.
📌Prometheus is often used in conjunction with other DevOps tools, such as Grafana for visualization and Kubernetes for orchestration.
