+====== Prometheus Overview ======
+**Prometheus** is an open-source monitoring and alerting toolkit designed for reliability and scalability.
+It collects, stores, and queries time-series data, and is widely used to monitor applications, systems, and services.
+Official website: [[https://prometheus.io|prometheus.io]]
+===== Key Features =====
+  * **Dimensional Data Model**
+    * Time series are identified by a metric name and key-value pairs (labels).
+    * Provides flexibility to organize and query metrics.
+  * **Powerful Queries**
+    * PromQL (Prometheus Query Language) allows filtering, aggregation, and correlation of time-series data.
+    * Enables advanced dashboards, visualizations, and alerting.
+  * **Precise Alerting**
+    * Rules are defined in PromQL.
+    * Alerts leverage the dimensional model for flexible conditions.
+    * Integrated with Alertmanager for routing, notifications, and silencing.
+  * **Simple Operation**
+    * Independent server, relies only on local storage.
+    * Written in Go, distributed as single static binaries.
+    * Easy to deploy in diverse environments.
+  * **Instrumentation Libraries**
+    * Wide set of official and community libraries.
+    * Covers most major languages (Go, Java, Python, Ruby, etc.).
+    * Allows developers to expose custom metrics.
+  * **Ubiquitous Integrations**
+    * Hundreds of exporters and integrations available.
+    * Common use: Node Exporter, cAdvisor, Blackbox Exporter, etc.
+    * Easy to extract metrics from existing systems.
+===== Typical Use Cases =====
+  * Monitoring microservices and containerized applications (Kubernetes, Docker).
+  * Collecting system-level metrics (CPU, memory, disk, network).
+  * Application-specific instrumentation (business logic, API metrics).
+  * Centralized alerting with Alertmanager.
+  * Integration with Grafana for visualization.
+===== Benefits =====
+  * Open source and widely adopted in the industry.
+  * Strong ecosystem (exporters, integrations, community).
+  * Highly flexible query model and alerting system.
+  * Scales from single servers to large distributed clusters.
