Issue/Introduction
When performing maintenance tasks such as deleting an old virtual machine snapshot on the VCF Usage Meter (UM), customers may consider powering down the Guest OS (GOS) to accelerate the snapshot consolidation/deletion process.
This article outlines the operational impact on hourly metering data collection during the period when the Usage Meter virtual machine is powered off.
Environment
VCF Usage Meter 9.x
Cause
VCF Usage Meter collects product consumption data from VMware Cloud Foundation instances and other add-on products. VCF Usage Meter collects the data on an hourly basis and sends it to VCF Business Services console, which is a service that aggregates the data. VCF Business Services console then sends the data to the Broadcom Support Portal for invoicing.
Powering off the Usage Meter Guest OS stops the running collection services, preventing the system from querying target endpoints during the downtime.
Resolution
While powering down the Usage Meter VM can reduce I/O overhead and speed up disk consolidation during snapshot deletion, the following impacts must be considered:
Hourly Metering Interruption:
While the Usage Meter Guest OS is powered down, hourly metering data collection cannot run and metrics for those specific hours will not be gathered.
Automatic Resumption:
Once snapshot deletion is complete and the Usage Meter VM is powered back on, metering collection services will resume automatically without requiring manual re-configuration.
