Administration platforms are usually accompanied by monitoring tools that facilitate data analysis in order to find meaningful insights and empower administrators with knowledge that lets them optimize their cloud systems. Monitoring tools are used for cloud monitoring, performance management, automation, cost management etc. Over the last years, a number of cloud monitoring tools have been developed including Nagios, Prometheus and Zabbix (open source), CloudMonix, New Relic, AppDynamics, etc. These provide the ability to collect and visualise information using table and graphs, analyse historical trends, create alerts and conduct a variety of functions from a single web-based console.
