An updated rhevm-dwh package that fixes one bug is now available.
The Red Hat Enterprise Virtualization Manager Data Warehouse package providesthe ETL process and DB scripts to create a history database API.
It also enablesSQL BI reports creation for management and monitoring.Changes to the ovirt-engine-dwh component:* Previously, in large environments the delete job took longer than it shouldhave (around 5 hours).
This caused a load on the sampling process, data was notdeleted, and a backlog was created for large sampling tables such asvm_interface_samples_history and vm_disk_samples_history.
This release adds amechanism that will allow the samples deletion process to become more aggressiveaccording to the following parameters: the number of times the deletion loopruns; the Initial and Increment values; and the number of iterations betweenincrements.
In addition, the DWH_LIMIT_ROWS parameter enables updating thehourly and daily deletion process with the amount of rows to be deleted in eachiteration.
The deletion process is now more dynamic, and can be customizedaccording to the environment, so the delete process will not take longer than 5hours. (BZ#1328709)
