Prometheus

Prometheus is an open-source systems monitoring and alerting toolkit originally built at SoundCloud. It collects and stores metrics as time series data, meaning metrics information is stored with the timestamp at which it was recorded, alongside optional key-value pairs called labels. It features a multi-dimensional data model, a flexible query language (PromQL), and supports service discovery and integration with various systems.

Also known as: Prometheus Monitoring, Prometheus TSDB, Prometheus Server, PromQL Engine, Prometheus Alertmanager

🧊Why learn Prometheus?

Developers should learn Prometheus for monitoring cloud-native applications, microservices, and containerized environments like Kubernetes, as it excels at collecting metrics from dynamic targets and providing real-time insights into system performance and reliability. It is particularly useful for setting up alerting based on defined thresholds, troubleshooting issues through its powerful querying capabilities, and integrating with visualization tools like Grafana for dashboards.
