There are already many outstanding open-source monitoring systems. However, with rapid growing businesses and specific requirements of internet companies, the existing open-source monitoring systems are not better enough on performance and scalability. 

Under the situation, Open-Falcon’s main distinguishing features compared to other monitoring system are: 

  • Scalability: Scalable monitoring system is necessary to support rapid business growth. Each module of Open-Falcon is super easy to scale horizontally. 
  • Performance: With RRA(Round Robin Archive) mechanism, the one-year history data of 100+ metrics could be returned in just one second. 
  • High Availability: No criticle single point of failure, easy to operate and deploy. 
  • Flexibility: Falcon-agent has already 400+ built-in server metrics. Users can collect their customized metrics by writing plugins or just simply run a script/program to relay metrics to falcon-agent. 
  • Efficiency: For easier management of alerting rules, Open-Falcon supports strategy templating, inheritance, and multiple alerting method, and callback for recovery. 
  • User-Friendly Dashboard: Open-Falcon could present multidimensional graph, including user-defined dashboard/screen.
