Appendix C. Performance Toolbox for AIX Commands

Following is a list of Performance Toolbox for AIX commands and AIX Operating System commands related to performance tuning:

a2ptx

A program to generate recordings from ASCII files.

azizo

The main program for analyzing recordings.

bf

Analyzes the memory usage of applications.

bfrpt

Reports on the memory usage of applications.

chmon

A sample program written to the data-consumer API.

fdpr

A performance tuning utility for improving execution time and real memory utilization of user-level application programs.

filemon

Monitors the performance of the file system, and reports the I/O activity on behalf of logical files, virtual memory segments, logical volumes, and physical volumes.

fileplace

Displays the placement of file blocks within logical or physical volumes.

filtd

The filtd programs allow you to define new statistics from existing ones through data reduction and alarms that are triggered by conditions you define and which can execute any command you desire.

genkex

The genkex command extracts the list of kernel extensions currently loaded onto the system and displays the address, size, and path name for each kernel extension in the list.

genkld

The genkld command extracts the list of shared objects currently loaded onto the system and displays the address, size, and path name for each object on the list.

genld

The genld command extracts a list of loaded objects for each process currently running on the system.

lockstat

Displays simple and complex lock contention information.

lvedit

The logical volume editor is used for interactive definition and placement of logical volumes within a volume group. This command does not apply to AIX Version 4.2 or later.

netpmon

Monitors activity and reports statistics on network I/O and network-related CPU usage.

ptxconv

A program to convert between Performance Toolbox for AIX Version 1.1 to Version 2 or Version 1.2 recording file format.

ptxmerge

The ptxmerge program allows the user to specify up to 10 input files that are to be merged into one file.

ptxrlog

A program to create ASCII or binary recording files.

ptxsplit

A program to split recording files into multiple files.

ptxtab

A program to tabulate the contents of recording files.

rmss

Simulates a system with various sizes of memory for performance testing of applications.

stem

Allows insertion of instrumentation code at the entry and exit points of existing program and library subroutines.

stripnm

Displays the symbol information of a specified object file.

svmon

Captures and analyzes a snapshot of virtual memory.

syscalls

Provides system call tracing and counting for specific processes and the system.

tprof

Reports CPU usage.

xmpeek

The xmpeek program allows you to ask any host about the status of its xmservd daemon.

xmperf

The xmperf program allows you to define monitoring environments to supervise the performance of the local AIX system and remote systems.

xmscheck

When xmservd is started with the command line argument -v, its recording configuration file parser writes the result of the parsing to the log file.

xmservd

The xmservd daemon is always started from inetd. Therefore, command line options must be specified on the line defining xmservd to inetd in the file /etc/inetd.conf.

3dmon

The 3dmon program is an X Window System based program that displays statistics in a 3-dimensional graph where each of the two sides may have up to 24 statistics for a maximum of 576 statistics plotted in a single graph.

3dplay

Beginning with Version 2.2., 3dplay is provided to play back 3dmon recordings in the same style that the data was originally displayed.
