summary: Systemtap static probes test
|
||||
description: |
|
||||
This test checks basic functionality of Python's systemtap static
|
||||
probes. It runs list & top systemtap scripts (examples from the
|
||||
python rpm) and then a python script using the "random" module.
|
||||
Finally it checks that the "random" module is correctly listed in
|
||||
the output of both systemtap scripts.
