Busy and quiet times of queries and DTPs

The analysis provides an overview of busy and quiet times of queries and DTP loads which were executed on all InfoProviders on a monitored system. The heatmap shows a total number of queries, DTPs or their sum. You can switch it with buttons Combined (Query & DTP), DTP or Query. Data is aggregated by weekdays and hours and it can be filtered by specific InfoProvider or by analyzed period. This analysis can help you to find quiet hours e.g. for operations which need more system resources. Also the busiest hours can be examined and their content can be split into other less busy hours.

InfoProviders size

The analysis provides an overview of all InfoProviders in the system divided into 3 categories. Each category represents size of InfoProviders that correspond to a particular group. E.g. "10%" group represent first 10% largest InfoProviders and their corresponding size. By clicking on a bar, application will be redirected to "Top InfoProviders" analysis, where "Top %" filter will be applied accordingly.

InfoProviders by year

This analysis provides an overview of InfoProviders in the system. Two charts are displayed here:

• Distribution by InfoProvider type - displays whole system per InfoProvider type
• InfoProviders - objects in the chart are sorted by size by default and can be further filtered

Both charts always display last 4 years + all others merged into other group (e.g. 2013 and lower) based on amount of InfoProvider data that belong to the group.

You can filter data and also switch to the table view for more detailed information where data can be downloaded into a CSV file for further processing.

It is possible to switch color mode of bottom chart to "Query usage". This colorizing mode groups data in InfoProvider by their respecting reporting usage. All data that were reported on less than 10 times are colorized with blue color and all data reported on more than 1000 times are colorized with red color. Warm data colorized with orange color belong to the category between these two threshold values.

NLS potential

Based on the analysis performed in the system, the visualization provides you with an overview on the potentials for archiving of particular object types (such as InfoCubes, DataStore objects, Write-Optimized DSOs) in form of column charts.

Data distribution analyses

Anchor
Data distribution analysis Data distribution analysis

These analyses provide information about how data is distributed in InfoProviders based on a specified characteristic and based on how many times these data areas were accessed by reporting (queries). The number of Data distribution analysis tiles depends on the settings on the central system. By default the BW analysis is delivered with only one predefined Data distribution analysis. The Data distribution analysis tile displays the number of analyzed InfoProviders which contain the specified characteristic. The below figure displays temperature based data categorization which is a type of data distribution and is by default included in the package.

...

The columns number of queries and size of data areas depend on data distribution settings of a particular analysis. These columns are created based on data groups you specify in your analysis. See (DI-1904) Define the Data Distribution Analysis for details about how to define data distribution and it's respective data groups for analysis. Each of these columns contains a sum (for sizes) and sum (for the use) of corresponding data area values. The footer of the table displays the number of records was already loaded to the table. This number will gradually increase, as you scroll down in the table.

You can filter the content of a table column by clicking on the column header. There is also a possibility to download the table content (without chart columns) into a csv. file by clicking on  toolbar button. You can also hide/show specific column groups by clicking on column group in View options toolbar. You can sort results based on field of your preference, by clicking again on column header:
