This document discusses adopting DevOps practices like continuous software delivery and monitoring systems. It recommends building an alerting system using tools like Ansible, Consul, Prometheus, and AlertManager to monitor systems and services. Prometheus is an open-source monitoring system that scrapes metrics via HTTP from configured targets and services. It has a flexible query language and stores time series data. The document provides an overview of how these tools work and their key features to help with DevOps practices like service discovery, health checking, and alerts.

• Multi-dimensional data model with time series data identified
by metric name and key/value pairs
• Flexible Query Language
• No Reliance on distributed storage, single server nodes are
autonomous
• Time Series Collection via pull mode over http
• Pushing time series is supported via intermediate gateway
• Targets are discovered via service discovery or static
configuration
• Multiple modes of Graphing and dashboarding support
