Prometheus is a very powerful open-source monitoring and alerting system suitable for dynamic environments like in Cloud space. That collects metrics from monitored targets by scraping metrics HTTP endpoints on these targets.

Prometheus is capable of recording any purely numeric time series, for both machine-centric monitorings like Linux systems as well as monitoring of highly dynamic service-oriented architectures.

Prometheus server-This scrapes and stores time series data from client systems and applications.
