running performance tests before , during and after a task 2

[proksr]

Hi,
I need to run performance monitoring tests on 10 AIX 5.3 servers.
I need mem, cpu, IO, sandisk performance with timestamp.
This test must start running b4 a load is put on the system and it should keep running while the load is there and keep running after the load is removed. Then I should stop the test and get the output. The output must be stored in a file so it can be analysed later.
any help is greatly appreciated.
thx.

You can run sar, iostat and vmstat in background redirecting the output to 3 files, and analyse these files later.
See man pages for more info about the outputs you need.

Yes MoreFeo is right

I used these commands usually to monitor the performance in crontab:

0 9 * * * sar -P ALL 10 360 >> /tmp/sar.out
0 9 * * * iostat 10 360 >> /tmp/iostat.out
0 9 * * * vmstat -I 10 360 >> /tmp/vmstat.out

If you are running LPARs try topas -C! very nice live monitoring command for all LPARs (5.3s).
