We will contact you as soon as possible.
Grafana 8 support
BVQ finally updated from Grafana 6.4 to Grafana 8.1 to fix several security vulnerabilities and support many new Grafana features. As the Grafana project changed its internal plugin architecture the BVQ Datasource plugin was rewritten and extended.
Depreciations and fundamental changes prevent a migration of Grafana 6 dashboards. Therefor all Dashboards have to be rebuilt or manually migrated.
To support this migration process BVQ has an option to install Grafana 6 and 8 side by side. The installer will provide the following option:
Grafana 8 will use the configured Grafana port and Grafana 6 will switch to "configured Grafana port" + 1 (e.g. Grafana was installed on port 3000. After an upgrade to BVQ 2021.H2.2 Grafana 8 will use port 3000, Grafana 6 will still be accessible through port 3001)
BVQ Datasource Features:
The BVQ Datasource plugin allows to connect Grafana to a BVQ Server and to visualize its data. Hence, the BVQ Server must be up and running.
QUERY MODE "Chart"
This mode is designed to get historical data in timeseries format that can be used in all panels supporting this format. Primarily the Timeseries panel. QUERY MODE "Chart" has six options:
|TYPE||Use Topology or Performance to select the type you want to choose from. All other options depends on the TYPE option. For Topology only numeric attributes are available.|
|FROM||Select the object type. The object type is responsable for the metrics you can choose. If TYPE ist set to Performance only object types with native performance data are available.|
|REACHABLE BY||Depends on the available dashboard variables. BVQ will only show data where a connection between "FROM object type" and the variable used here can be made.|
|WHERE||Use a BVQ filter to limit the results based on "FROM object type". All filters of the BVQ filter syntax are available. For example: name contains "svc".|
|GROUP BY||Aggregate all objects to another object type level and show the results as single line. E.g. "FROM SVC VDisk" and "GROUP BY SVC Cluster" will aggregate all individual SVC VDisk within an SVC Cluster.|
|METRICS||Choose one or multiple metrics or attributes to show in the panel. The available options are depending on the selected TYPE and FROM option.|
Important: Based on the requested time range, interval, objects and metrics data load can cause higher BVQ Server load and longer response times!!!
QUERY MODE "Topology table"
This mode is designed to get tabular data for a specific point in time without a history. The point in time is calculated form the TO date of the chosen time range. QUERY MODE "Topology table" has three options:
|SELECTION PATH||The SELECTION PATH is comparable to the BVQ Pathselector in the Expert GUI and let you create a hierarchy. Each path element can be filtered with the BVQ Filter Syntax and allows columns for this object type.|
|COLUMNS||The COLUMNS option allows to choose attributes, capacities and linked objects for each object type used in the SELECTION PATH. Performance data are only available for the last object type used in the SELECTION PATH.|
|REACHABLE BY||To limit the output based on a Grafana dashboard variable it is possible to use the REACHABLE BY option. To use this option a dashboard variable of the same object type as the last selection path element is necessary.|
The Topology mode is much faster as it only shows a point in time. It is suitable for stats and table panels.
The Topology table is a replacement of the BVQ Favorite Datasource and removes the requirement of creating a favorite in the BVQ Expert GUI prior to launching the information within Grafana.
QUERY MODE "Event table"
This mode is designed to get tabular data for system events and has three options:
|EVENT SOURCE||This variable is mandatory and based on dashboard variables. It is only possible to select an event source if a dashboard variable with an appropriate object type exists. The results will be restricted based on the object type and the selected value in the Grafana dashboard variable. The additional option "show events of the whole system" provides an easy way to show all events for the whole system.|
|IDENTIFIER LENGTH||There are 3 options to control the identifier length. Shorter identifier might work for scoped dashboards but might cause duplicates.|
|EVENT LEVEL||Limit the event levels you want to show. Available levels differ based on the selected source.|
As some platforms provide a massive amount of events the output is limited to 1000 events!!!
BVQ default Dashboards
The BVQ default Dashboards have been migrated and improved for Grafana 8.
New Grafana Features
As the update from Grafana 6 to Grafana 8 skips multiple major and minor versions with plenty of new features, please take a look at the Grafana website to review all details: https://grafana.com/docs/grafana/next/whatsnew/
Grafana itself improved in many different areas; especially the UI was redesigned for better usability. The following links provide an overview of the most BVQ relevant changes:
- Panels: https://grafana.com/docs/grafana/next/panels/
- Transformations: https://grafana.com/docs/grafana/next/panels/transformations/
- Visualizations: https://grafana.com/docs/grafana/next/visualizations/
- Templates and Variables: https://grafana.com/docs/grafana/next/variables/
Brocade FOS 9 support
BVQ now supports Brocade switches running Fabric OS 9.x and there are some enhancements in the Brocade (REST) module:
- new attributes for objects type Brocade switch and Brocade switch port
- new metrics for object type Brocade switch:
- two new object types to visualize Brocade's Monitoring and Alerting Policy Suite (MAPS): Brocade Policy and Brocade Rule.
BVQ displays all Brocade Rules which either belong to the active Brocade Policy or are not predefined.
Systems Health Map performance improvements
In large environments, loading time for the Systems health map was unacceptably slow. To speed it up, the way of calculating alert rule results and display them in the Systems health map has been changed.
As a result, BVQ no longer displays absolute numbers in the Systems health map but percentages.
The absolute numbers of objects in each state can still be seen in the detail view of each alert rule:
In addition, the presentation of the Systems health map on the Home-screen has been changed from sunburst to stacked bar chart. Again, this change has the advantage of loading the data much faster than before. The numbers shown here represent the amount of objects per alert rule in a certain state.
Call Grafana directly from BVQ Server
There is a new menu option in the BVQ WebUI which allows you to jump to Grafana directly.
The URL is dynamically created from the URL the user is using to access the BVQ server and the Grafana port selected during setup. If this URL needs to be adjusted, navigate to Adminstration → Grafana configuration and enter the correct URL for your Grafana setup.
