A highly flexible capacity charting system is finally available inside the BVQ GUI.
In the past, capacity charting was only possible by using predefined reports with a fixed set of object types. It is now possible to chart all capacities the object is aware of. Charting options are provided as absolute and relative metrics for provider and consumer.
The usage is similar to performance charting with some minor differences:
Capacity charting performance depends on different conditions:
Introduction of Design IO Density for MDisk group & Storage Class objects
With previous versions of BVQ it was difficult to simulate what would happen if an MDisk group had more or less IO density.
The introduction of a "Design IO density" for MDisk groups and Storage class simplifies this simulation.
"Design IO density" (DIOd) co-exists with the already existing "Estimated IO density" (EIOd). While the latter is derived from IO density configured per BVQ Disk Array, the first one is configurable per MDisk group.
Analogue to "Default Design Response Time", a "Default Design IO density" (DDIOd) can be configured per Storage Class. If this Storage Class is defined for the MDisk group, DDIOd is automatically transfered to it as DIOd.
DIOd values can be added and modified using the MDisk group editor:
Or you can define DDIOd in the Storage Class editor:
Multiple DIOd related values and calculations can be displayed in the table views:
The new DIOd parameter is also reflected in the Object Coloring: In addition to the existing EIOd coloring, DIOd can also be displayed using the same coloring rules.
BVQ Reporting is now enhanced with a powerful scheduling. Each report can be scheduled easily by using the schedule button in the template list.
The schedule will be defined using a cron syntax. To simplify the process a simple and advanced option is availible.
Range will define the time period the report will be generated for. It is allways the schedule time-range.
Schedule time: 11.12.2017
Report timeframe: 27.11.2017 - 11.12.2017
VDisk copy capacity difference
In most cirumstances different configurations of vdisk copies are unwanted. They might occur in historically grown configurations and are difficult to detect.
To make detection easier a capacity inconsistency factor has been added for
Primary to secondary capacity difference (P2S)
This new attribute can be used inside tables and for any advanced filtering.
Enhanced path based charting (PBC)
While path based charting feature (PBC) was introduced in BVQ 5.3 with some missing objects it is now available for all objects in BVQ. You are now able to create predifined charts with aggregated metrics of your own custom selections.
We added PBC support for the following metrics for all objects which are aware of these metrics:
For further informations about PBC see: Release notes BVQ 5.3: Path based charting
PBC Chart report snippets
All PBC chart favorites are now available as snippets for report generation:
Enhanced BVQ Server user roles
To support more dedicated users we extended the user role concept and the predefined user roles. It is now possible to choose out of 10 predefined roles that can be assigned in all kinds of different combinations. This will allow to create read-only users, dedicated users for scanner managementes etc.
To view the detailed permissions of a user role, just click the next to the role name.
The roles Alert rule administrator and Alert rule viewer are defined ahead for the upcoming alerting features in the future.
BVQ Server Maintenance Mode (v5.4.1)
BVQ Server now has a maintenance mode which is started if essential information that prevents BVQ from operating is missing.
An administrative user is required to login to the server at http
The following circumstances trigger BVQ server maintenance mode:
Once logged in, the navigation panel on the left shows you which corrective actions need to be taken. Those items are marked with .
Although you will be automatically directed to the first item requiring action (), you can review the other ones ()as well.
Once all steps are completed, BVQ server will leave maintenance mode and restart the server in normal operation.
The regular server start might take some minutes so don't be scared if the server login page isn't available immediately.
