What is Prometheus
Prometheus is a monitoring system designed to collect system metrics and alert on changes. It can be used to monitor server, container, and application performance, and to diagnose and troubleshoot issues.
Prometheus can collect data from a variety of sources, including system logs, process logs, and network interfaces. It can then use this data to generate alerts and graphs and to store historical data for later analysis.
Prometheus can be used to monitor a single system or an entire network. It can also be used to monitor systems in production or in development.
Prometheus has a variety of features that make it an ideal monitoring system. These features include:
- Easy to deploy
- Multiple Graphing and dashboards are supported
- Time series data collection happens via the Pull model over HTTP
- Highly Scalable
- Stores historical data
