Viewing the Volume Report for the data warehouse
The Volume Report page displays values and charts for volumes processed by the TrueSight Capacity Optimization data warehouse components.
This topic contains the following sections:
To access the report
- Navigate to Administration > DATA WAREHOUSE > Status.
- In the Volume section, click the Volume Report link.
The Volume Report page is displayed. The following image shows an example of the Volume Report page.
To view the data load capacity used
The Data Load Capacity Used table lists the load capacity and status, as shown in the following example:
Loaded daily (last 30 day average)
|Estimated daily capacity (8 hour period)||10.34million rows|
|Estimated daily capacity (24 hour period)||31.03million rows|
|Load status: OK|
The following load capacity values are listed:
- Loaded daily (last 30 day average): Number of rows in the data flow report that are loaded daily. The value is averaged out for the last 30 days.
- Estimated daily capacity (8 hour period): Represents the estimated maximum daily throughput sustainable by the deployment, considering a processing time of 8 hours.
- Estimated daily capacity (24 hour period): Represents the estimated maximum daily throughput sustainable by the deployment, considering a processing time of 24 hours.
The ideal processed volume values should be below the Estimated daily capacity (8-hour period) value. The system works even above the prescribed threshold, but performance is affected.
If the processed volume value reaches the Estimated daily capacity (24-hour period) value, the system does not have enough capacity to meet the volume requirement. In this case, you should investigate the root cause of the volume increase (for example, new ETLs are added) and do a new sizing to improve the system performance.
To view the Data flow report table
The Data flow table lists the
Referring date (timestamp): Current day statistics are updated at regular intervals
Number of rows processed from stage tables (sum)
Number of derived rows (sum)
Number of rows stored in the D and MDCH tables
Number of rows generated due to a split, having a "TS+duration" that exceeds the hour limit (sum)
|Processing Throughput [rows/sec]|
Total processing count divided by total processing time (aggregation on all DWH threads)
|Thread Processing Throughput [series/sec]|
Total number of rows processed, divided by the thread processing time
|Processing Time [sec]|
Number of seconds spent in processing, with at least one active thread (sum)
|Total Read/Write Rows|
Number of rows processed by all threads (sum)
|Stored Rows Conf|
Number of rows stored in the CONF_VARIATION table (sum)
|Stored Rows Detail|
Number of rows stored in the DH table (sum)
|Stored Rows Hour|
Number of rows stored in the DETAIL table (sum)
To view the Warehouse Timing Report
To view the Warehouse Timing Report, click the Warehouse Timing Report link located below the Data flow table on the Volume Report page. The Warehouse timing report page opens and displays the Warehouse Timing Report table. The table contains the following information:
|ts||Referring timestamp for reported statistics (rolled each hour)|
Amount of seconds accumulated (starting from the ts column)
Identifier for the data warehouse method/ phase measured
Cumulative amount of milliseconds spent in the specific component
Average milliseconds required for a single execution
Peak time in milliseconds spent in the specific component
Minimum time in milliseconds spent in the specific component
Number of executions accumulated in the referred time period for the specific component
Click the Data flow report link located at the top of the Warehouse timing report page, to go back to the Volume Report page.
