Welcome to Vitrage documentation!
Vitrage is the OpenStack RCA (Root Cause Analysis) service for organizing, analyzing and expanding OpenStack alarms & events, yielding insights regarding the root cause of problems and deducing their existence before they are directly detected.
High Level Functionality
- Physical-to-Virtual entities mapping
- Deduced alarms and states (i.e., raising an alarm or modifying a state based on analysis of the system, instead of direct monitoring)
- Root Cause Analysis (RCA) for alarms/events
- Horizon plugin for the above features
High Level Architecture
Vitrage Data Sources are responsible for importing information from different sources, regarding the state of the system. This includes information regarding resources (physical, virtual, and applications) and alarms. The information is then processed into the Vitrage Graph. Currently Vitrage supports OpenStack datasources like Nova, Cinder, Neutron, Heat and Aodh, as well as external monitors like Nagios, Zabbix and collectd.
Vitrage Graph holds the information collected by the Data Sources, as well as their inter-relations. Additionally, it implements a collection of basic graph algorithms that are used by the Vitrage Evaluator (e.g., sub-matching, BFS, DFS etc).
Vitrage Evaluator coordinates the analysis of (changes to) the Vitrage Graph and processes the results of this analysis. It is responsible for executing different kind of template-based actions in Vitrage, such as to add an RCA (Root Cause Analysis) relationship between alarms, raise a deduced alarm or set a deduced state.
Vitrage Notifiers can be used to notify external systems of Vitrage alarms and states. Currently Vitrage has an Aodh notifier for raising Vitrage alarms in Aodh, and a Nova notifier for marking that the host is down.
