16.1 Data Integration Overview

The Data Integrator window controls the merging of measured, sampled, and event data to produce a uniform system and network resource utilization file (.MERG or .merg) and a report file (.PROC or .proc).

The merged file is also reduced in size in preparation for the analysis phase. In the Workload Analysis component, you read in the merged data after completing the classification step.

The report file contains user profile information for the merged data.

The Data Integrator window has panels in which you can indicate the time period for data integration, the data files to integrate, and options specific to OpenVMS and UNIX systems.

See Also OpenVMS Data Integration Overview UNIX Data Integration Overview

16.1.1 OpenVMS Data Integration Overview

For OpenVMS, data files that can be integrated include:

The Data Integrator component merges the .CPD, .EVM, and .DAT files to generate a single file .MERG file for each node.

For OpenVMS, you can also select different processing options.

See Also OpenVMS Data Integrator Performing Tasks in the Data Integrator Window

16.1.2 UNIX Data Integration Overview

For UNIX systems using FullSail data, all the data for one UNIX system can be contained in a single file of type .arc. You must therefore use the Data Integrator to separate the data according to node name. The resulting .merg files contain the measured process and configuration data for each node in the system. You must repeat the integration process for each node to be included in the model.

For UNIX systems collecting system accounting plus snapshot data, use .acct and .snap files to create a .merg file for each node to be included in the model.

For UNIX systems using DECps data, use .CPD files.

For UNIX systems using OpenAviator data, you will have data files for each node on which you collected data.

If you do not use the By Process, By Image button, you will not be able to define subclasses for your process data.

See Also By Process Toggle Button (OpenVMS)

16.19 Percent I-Stack to Merge Slider (OpenVMS)

The interrupt stack time is the total time that the CPU spends in the interrupt stack during the current interval record.

This slider specifies the percentage of interrupt stack time that you want distributed to processes. You can distribute all, none, or a portion of the interrupt stack CPU overhead to all processes. The default is 100%. Any interrupt stack time that is not distributed to processes is sorted into the last class.

The overhead CPU is calculated for each process based on its percentage of the system-wide total disk I/O, which includes fault I/O.

If the overhead CPU time distributed to interactive processes causes the process total CPU time to exceed the process response time, then the overhead is not added and a warning is displayed.

See Also Percent Busy Wait to Merge Slider (OpenVMS)

16.20 Percent Busy Wait to Merge Slider (OpenVMS)

This slider specifies the percentage of busy wait overhead time (also called multi-process synchronization time) that you want distributed to processes. You can distribute all, none, or a portion of the busy wait CPU overhead to all processes. The default is 100%. Any busy wait time that is not distributed to processes is sorted into the last class.

The overhead CPU is calculated for each process based on its percentage of the system-wide total disk I/O, which includes fault I/O.

If the overhead CPU time attributed to interactive processes causes the process total CPU time to exceed the process response time, then the overhead is not added and a warning is displayed.
