The BigFoot tool is packaged as part of the Performance Toolbox for AIX. To determine whether BigFoot is available, use:
lslpp -lI perfagent.tools
If this package has been installed, BigFoot is available.
The BigFoot tool collects the memory footprint of a running program. It reports the virtual-memory pages touched by the process. BigFoot consists of two commands:
| bf | |
| collects information about pages touched during the execution of a program. It generates the complete data from the run in a file named __bfrpt. | |
| bfrpt | |
| filters the __bfrpt file to extract the storage references made by a given process. | |
