An open-source monitoring system with a dimensional data model, flexible query language, efficient time series database and modern alerting approach.
Prometheus, a Cloud Native Computing Foundation project, is a systems and service monitoring system. It collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts when specified conditions are observed.

Prometheus is a free software application used for event monitoring and alerting. [2] It records metrics in a time series database (allowing for high dimensionality) built using an HTTP pull model, with flexible queries and real-time alerting.
In Greek mythology, Prometheus (/ p r ə ˈ m iː θ i ə s /; Ancient Greek: Προμηθεύς, [promɛːtʰéu̯s], possibly meaning "forethought") [1] is one of the Titans and a god of fire. [2]
Now we have Prometheus up and running and scraping its own metrics every 15s. Prometheus has standard exporters available to export metrics. Next we will run a node exporter which is an exporter for machine metrics and scrape the same using Prometheus.
Prometheus is configured via command-line flags and a configuration file. While the command-line flags configure immutable system parameters (such as storage locations, amount of data to keep on disk and in memory, etc.), the configuration file defines everything related to scraping jobs and their instances, as well as which rule files to load.
