Metrics - dashboard

The Metrics - dashboard tab shows summaries of the artifact measurements stored by Rational® Asset Analyzer for assets in the inventory database.

This tab is accessible from the Home page. It displays a pie chart or table of details for each of the following measurements calculated by Rational Asset Analyzer. To use the Metrics - dashboard tab, click the pieces of the pie chart to open a "File summary" page that lists the files measured.

File size (bytes): The size of files in the inventory in bytes.
Comment lines: The number of comment lines in each file-type group.
Lines of code: The number of lines in files in the inventory.

The Metrics - dashboard tab also displays a table for each of the following measurements calculated by Rational Asset Analyzer:

Cyclomatic complexity: The number of linearly-independent paths through a program module to determine the stability and level of confidence in a program. Programs with lower cyclomatic complexity are easier to understand and less risky to modify. This measurement is calculated for COBOL and PL/I programs. See the Related Concepts for information on how this value is calculated.
Essential complexity: The number of entry points, termination points, and nonreducible nodes (unstructured exits from blocks of code) to determine how well structured a program is. The closer to 1 this value is, the better the structure of the program. This measurement is calculated for COBOL and PL/I programs. See the Related Concepts for information on how this value is calculated.
Halstead effort: The complexity of a program to determine the mental effort required to develop or maintain a program. The lower the value of this measure, the simpler a change to the program will be. This measurement is calculated for COBOL and PL/I programs. See the Related Concepts for information on how this value is calculated.

For each of these types of measurements you can view a table that reports the following statistics. To switch from the pie chart to the table, click the table icon for the measurement type.

Note: You can maximize or minimize the view for these charts by clicking the magnifying glass icon.

Language: The language (such as Assembler, Java™, or PL/I) or tagging system (such as HTML, XML, plain text) used in the file.
Type: The file type, such as manifest (MF), include file (INCL), GIF, or JPG.
File count: The total number of files for which each measurement has been taken. You can click this number to open a "File summary" page listing the files measured.
Minimum: The smallest measurement taken for the group of files measured.
Maximum: The largest measurement taken for the group of files measured.
Average: The average measurement for the group of files measured.
Sum: The total measurement for the group of files measured.
Standard deviation: A measure of statistical dispersion. Standard deviation measured how spread out the values for each measurement are. If the data points are all close to the mean, then the standard deviation is close to zero. If many data points are far from the mean, then the standard deviation is far from zero. If all the data values are equal, then the standard deviation is zero.
Percentage: The total measurement for the group of files measured divided by the sum of all totals.
