Filtering by Key Metric Filtering by Number of Lines Using Filter Combinations Examples Example 1 Example 2
Application Performance Snapshot User's Guide for Linux* OS

Using Filter Combinations

By default, both filters described above are enabled. The default threshold for TIME and VOLUME is 1%, default value for the number of lines filter is five. Thus, the default tool behavior is the same as with the key combination -V 1 -T 1 -N 5.

NOTE:
Note

Filter by key metric is applied first. Filtering by number of lines filters only the remaining lines.

Examples

In all the examples, the Message Size chart containing 28 lines is used.

Example 1

To use the default options, enter: 

$ aps-report -m aps_result_<postfix>

This command line is equal to this one: 

$ aps-report -m -V 1 -T 1 -N 5 aps_result_<postfix>

Output:

The volume filter hides the bottom lines with Volume(%) less than 1% (15 lines). The remaining 13 lines are less than the number of lines to be displayed. Therefore, the filter by number of lines will not be applied.

Example 2

To hide the lines with VOLUME less than 1% (default threshold), and display two top lines, two middle lines, and two bottom lines of the remaining lines, enter: 

$ aps-report -N 2 -m aps_result_<postfix>

or 

$ aps-report -V 1-N 2 -m aps_result_<postfix>
