csatari c9ea8ea4a1 Aligning install guide with the Pike doc structure

In Pike OpenStack documentation is changed in a way that the project repos
contain most of the documentation material [1]. This affcects how the doc
folder shall be strucutred inside the project repo. With this change I
align the install guide to the new structure and correct the warnings
during the document generation. The overall work is tracked in [2].

Raw Blame History

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.
