Resource management tools help you monitor performance and identify
performance issues. There are many ways to collect the system data
you need to investigate performance problems.
Linux standard tools are available on every Linux distribution.

'pstree' shows the dependencies and relationships
of applications. Similar to 'ps -eafx'.
Example:
user@pserver1:~> pstree
...
|-4*[nfsd]
|-nmbd
|-nscd---nscd---5*[nscd]
|-ntpd
|-portmap
|-rpc.mountd
|-rpc.statd
|-safe_mysqld---mysqld---mysqld---mysqld
|-2*[screen---bash]
|-scsi_eh_0
|-scsi_eh_1
|-smbd
|-sshd-+-2*[sshd---sshd---bash---vim]
| |-sshd---sshd---bash---su---bash
| `-sshd---sshd---bash---pstree
`-syslogd

'top' prints out system data per process. It
shows an overview on the currently running system processes.
The top command itself consumes CPU resources.
Example:
[user@pserver1]$ top
1:40pm up 3:17, 11 users, load average: 0.00, 0.02, 0.03
134 processes: 127 sleeping, 6 running, 1 zombie, 0 stopped
CPU states: 1.9% user, 1.7% system, 0.0% nice, 96.2% idle
Mem: 1030464K av, 675028K used, 355436K free, 0K shrd, 156256K buff
Swap: 1663160K av, 0K used, 1663160K free 296068K cached
PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND
1746 wolf 15 0 54772 14M 11600 R 1.1 1.4 0:00 kdeinit
6147 wolf 15 0 1080 1080 840 R 0.9 0.1 0:00 top
Print the output of the 'top' command to a
file:
top d 4 b i > out
d refresh rate in seconds
b batch
i only active processes

Retrieves data directly from the 'proc'-filesystem
('/proc') and prints them to the screen. It shows
the system utilization (CPU/Memory/ I/O).
Example:
[user@pserver1]$ vmstat 3
procs memory swap io system cpu
r b w swpd free buff cache si so bi bo in cs us sy id
0 0 0 0 663248 24204 196816 0 0 66 32 582 663 4 1 95

This package consists of several Linux tools to collect
system data.
Open source package: http://perso.wanadoo.fr/sebastien.godard/
Recompile the package on Linux on System z to use it.
For our measurements we used version 6.0.2 as contained
in SLES9 and RHEL4.
The 'sysstat' package consists of the
following components:
'sadc' data gatherer, stores data
in binary file'sar' reporting tool, reads binary
file created with 'sadc' and converts
it to readable output'mpstat' processor utilization'iostat' I/O utilization
|
- Start
-
/usr/lib/sa/sadc [interval [count]] [outputfile]
- Example
-
machine1:~ # /usr/lib/sa/sadc 4 2 sadc.outfile
- Stop
-
'killall sadc' or 'kill procnr'
|
- Creating report with all options
sar -A -f <sadc-outputfile> <outputfile> - Example
-
machine1:~ # sar -A -f sadc.outfile > sar.outfile
machine1:~ # cat sar.outfile

OProfile offers profiling of all running code on Linux systems,
providing a variety of statistics. It is released under the
GNU GPL. OProfiler consists of a kernel driver and a daemon
for collecting sample data, and tools for information generation.
For a documentation of the OProfile commands see http://oprofile.sourceforge.net/docs/.
- Check that you have at least a SLES9 SP2 installed
including the OProfile kernel module; this is at least
kernel level kernel-s390(x)-2.6.5-7.191.
- Be sure to have installed the packages
popt-devel
and qt3-devel as contained with kernel-s390(x)-2.6.5-7.191.
- Download the latest release of the OProfile user
space tools from
http://oprofile.sourceforge.net/download/.
- Extract the source of the OProfile user space tools
to the current directory:
tar xvzf oprofile-0.9.1.tar.gz
- Change to the OProfile source directory:
cd oprofile-0.9.1
- Configure the make files and the build environment:
./configure -–with-kernel-support –-with-qt-libraries=/usr/lib/qt3/lib64
./configure –-with-kernel-support
-–with-qt-libraries=/usr/lib/qt3/lib for
a 31-bit distribution
makemake install
|
- Check that you have at least a RHEL4 U2 installed
including the OProfile kernel module; this is at least
kernel level kernel-2.6.9-22.EL.
- Be sure to have installed the package
oprofile-0.8.1-21
as contained with kernel-2.6.9-22.EL.

The OProfile user space tools require to switch on the
hertz timer with the sysctl command
sysctl -w kernel.hz_timer=1
If the system is configured to not to run with hertz timer,
disable the hertz timer after profiling with
sysctl -w kernel.hz_timer=0
