Profile Bar Graph
The Profile Bar Graph (or histogram) is produced by using the GRAPH TYPE=PROFILE or WLMGRAPH TYPE=PROFILE Analyzer control statement.
The data in this graph can be used to locate peaks and valleys in the performance of the system over time of day.
The Profile Bar Graph is scaled to the largest LIMIT= value that is specified in the GRAPH or WLMGRAPH statement. The default limit is 100 (coded LIMIT=10000). Up to 16 measures can be specified; each measure is represented on the graph by a different character. When more than one measure is represented, the one with the smallest value is displayed first on the line.
The Extractor statements required for the Profile Bar Graph are dependent upon the information to be graphed. (See Record types for information about the record types generated by each Extractor statement and a description of the specific type of data collected by each Extractor statement.)
One line on the graph is produced for each interval specified in the GRAPH or WLMGRAPH command. If the interval default is used, one line is produced for each record interval encountered in the data.
The Profile Bar Graph is read from left to right. The value of each measure on the graph is determined by locating the rightmost character representing that measure; the value shown at that point is the value of the measure. For measures that have exactly the same value on the line, the character O is printed to indicate an overlap.
A sample of the Profile Bar Graph is shown in the following figure. In this figure, one measure, CPU, was selected.

The Profile Bar Graph is most effective when used over time to compare one time frame to another.

n REPRESENTS | character n used to represent each measure selected in GRAPH or WLMGRAPH statement |
DATE | date when samplings were made |
TIME | time frames at which samplings were made |
GRAPHIC DISPLAY OF INTERVAL TOTAL TIME | axis representing values for each measure, according to rightmost character Values can be percentages, numerical count, and so on, depending on the measure being scaled. |
