Partition Property screen on the HMC) for at least one partition, preferably the
Virtual I/O Server partition if not already done. To enable data collection on the
Virtual I/O Server, execute the oem_setup_env command and follow the
guidelines for AIX 5L. We outline them below.
Go to the /usr/lpp/perfagent directory and execute the script config_topas.sh
with the parameter add:
# cd /usr/lpp/perfagent
# ./config_topas.sh add
AIX Topas Recording (topas -R) enabled
# Sending nohup output to nohup.out.
This will add an entry to /etc/inittab and additionally start topas with the -R option
for continuous data recording, collecting cross-partition CPU usage data.
For daily performance records, go to the /usr/lpp/perfagent directory and execute
the script config_aixwle.sh with the parameter add:
# cd /usr/lpp/perfagent
# ./config_aixwle.sh add
Sending nohup output to nohup.out.
AIX Daily Recording Agent (xmwlm -L) enabled
#
This will add an entry to /etc/inittab as well as to the crontab and additionally start
the xmwlm command with the -L option for daily data recording, which includes
data from CPU usage as well as memory, disk, network, and kernel statistics.
The collected data of the topas -R command will be written to a file in /etc/perf.
The name of the file is dependent on the date, so it should look like the one in
Example 5-32
