Chapter 14. Install Time-Series-Database-as-a-Service

Time-Series-Database-as-a-Service (gnocchi) is a multi-tenant, metrics and resource database. It is designed to store metrics at a very large scale while providing access to metrics and resources information to operators and users.
For more information on using the Time-Series-Database-as-a-Service, see the Using the Time-Series-Database-as-a-Service section in the Logging, Monitoring, and Troubleshooting Guide.
Time-Series-as-a-Service is built around the following drivers:
storage
The storage driver is responsible for storing measures of created metrics. It receives timestamps and values and computes aggregations according to the defined archive policies.
indexer
The indexer driver is responsible for storing the index of all resources, along with their types and their properties. Time-Series-as-a-Service only knows resource types from the OpenStack project, but also provides a generic type so you can create basic resources and handle the resource properties yourself. The indexer is also responsible for linking resources with metrics.
The REST API exposed to the user manipulates both these drivers to provide all the features that are needed to provide correct infrastructure measurement.
