MAlt: Mail Performance Metrics

Due to the fact that Microsoft has dropped CERN's academic institute status, therefore leaving licensing 10 times more expensive, CERN has had to come up with an alternative to Microsoft products to try and phase out the need for their products and in turn save money. Mail is currently predominantly on Microsoft's Exchange servers. CERN is migrating its mail system, hosting 50TB+ of data on 40,000 mailboxes, from Microsoft Exchange to Kopano, an Open Source Linux-based system. The aim of this project is to consolidate the various system and application metrics in use in the new systems, and to develop on top of that an uniform visualisation layer, providing a facility to implement anomaly detection and event correlation. The data will be collected from different services, ranging from systems performance / monitoring, to web servers and back-end databases, to migration-specific tools. The project will make extensive use of free and open source tools such as Collectd, Telegraf and Filebeat to collect the data, ElasticSearch and InfluxDB to store it, and Kibana/Grafana to visualise it. The main operating system that will be used for the project is Cent-OS Linux version 7. Other tools that are going to be heavily used are Puppet (configuration management system), OpenStack (Infrastructure-as-a-Service cloud computing), Openshift (Platform-as-a-Service for web hosting) and Docker/Kubernetes (container platform).
