Data to Be Analyzed

Enter any of the following information:

Data

Specifies the source of data to be analyzed. Press MB1 on the Data option item and a menu appears. The menu lists daily data collection definitions in your local schedule file and history file definitions in your local parameter file.

Release on the item you want. The option menu disappears. The menu item you chose is now the current source for performance data. The default data source is daily data from the CPD collection definition.

Note: Changing the source of data may change how it can be classified and which nodes can be analyzed. If you have chosen a history file descriptor, the Classify By options are changed to reflect those specified by the descriptor's definition. If you choose daily data, Classify By options reflect all workload families currently defined in the parameters file. If a data source selection nullifies the current Classify By selection, the Classify By selection is reset to the default of None.

For daily collection definitions, the nodes specified by the collection definition are the only valid nodes for analysis. For this reason the source of the data should always be chosen ahead of the classification of the data and the nodes to be analyzed.

If you select archived data for processing, the history files will be locked, blocking any archiving process. Also, if an archiving process is in progress, the DECwindows interface will be suspended from reading the files until the archiving is complete.

Classified By

Specifies how the Performance Manager is to classify process activity in the Process Statistics Reports and in graphs presenting workload metrics. Press MB1 on the Classify By option item and a menu appears. The menu lists workload families. Release on the family name you want.

The default option is None, which results in the following summarizations. All graph data will be displayed in the workload “Other.” All Process Statistics reports will use the processing modes of Interactive, Batch, Network, or Detached.
