Chapter 13. 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-Series chapter in the Logging, Monitoring, and Troubleshooting Guide.
Note
Time-Series-Database-as-a-Service (gnocchi) is marked as Technology Preview for the Red Hat OpenStack Platform 8.
For more information on the support scope for features marked as technology previews, see https://access.redhat.com/support/offerings/techpreview/.
Time-Series-as-a-Service is built around the following drivers:
- storage
- The
storagedriver is responsible for storing measures of created metrics. It receives timestamps and values and computes aggregations according to the defined archive policies. - indexer
- The
indexerdriver 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. Theindexeris 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.
