Current Series Release Notes

23.0.0-48

New Features

  • Added the new power.state metric from virDomainState.

Upgrade Notes

  • The following meters were removed. Nova removed support for Intel CMT perf events in 22.0.0, and these meters can no longer be measured since then.

    • cpu_l3_cache_usage

    • memory_bandwidth_local

    • memory_bandwidth_total

  • Support for Open Contrail has been removed. Because no SDN is supported after the removal, the mechanism to pull metrics from SDN is also removed.

  • Python 3.8 support was dropped. The minimum version of Python now supported is Python 3.9.

  • Support for VMware vSphere has been removed.

Deprecation Notes

  • The [DEFAULT] hypervisor_inspector option has been deprecated, because libvirt is the only supported hypervisor currently. The option will be removed in a future release.
