OpenStack-compatible quota/usage tracking service
Limes
Limes is an OpenStack-compatible quota/usage tracking service, originally designed for SAP's internal cloud.
Pronounce the name like the Ancient Roman border wall, not like the fruit. (Mnemonic: The original Limes was installed when the Romans wanted to put a quota on Germanic land use.)
The idea: Automatic quota distribution
Limes can discover capacity and usage for various types of OpenStack resources. It can then be set up to distribute quota automatically among all projects in a dynamic and automated fashion. Both cloud admins and project admins have several knobs to control their quota assignments in a controlled fashion.
Unique features
- Limes records quota changes in the Open Standards CADF Format, and is compatible with other cloud based audit APIs (e.g. Hermes).
- Quota and usage data can be exposed as Prometheus metrics for monitoring and alerting.
