Prometheus

Prometheus is a leading open-source systems monitoring and alerting toolkit designed for reliability and scalability. Originally developed at SoundCloud, it is now a Cloud Native Computing Foundation (CNCF) project. Prometheus collects metrics from configured targets at given intervals, evaluates rule expressions, and can trigger alerts if certain conditions are met.

Features of Prometheus:

• Powerful multidimensional data model with time-series data identified by metric name and key/value pairs.
• Flexible query language (PromQL) for slicing and dicing collected time-series data.
• Efficient storage and retrieval of time-series data using a custom database optimized for metrics.
• Built-in alerting and integration with Alertmanager for notifying on critical events.
• Pull-based metrics collection and service discovery for dynamic environments like Kubernetes.

To get started with Prometheus on Ubuntu, run the following commands:
$ sudo systemctl start prometheus
$ sudo systemctl status prometheus
