Performance

[Jose Luis]

Hi,
(Tru64 5.1a)
What kinds of tools have I to analize the performance in the system (disks, CPU, network, mem, etc) besides of vmstat.
Thank's in advance.

Jose,

The vmstat command displays system statistics for virtual memory, processes, trap, and CPU activity.

The iostat command reports input and output information for terminals and disks and the percentage of time the CPU has spent performing various operations.

The collect utility enables you to sample many different kinds of system and process data simultaneously over a predetermined sampling time.

The Monitoring Performance History (MPH) utility is a suite of shell scripts that gathers information on the reliability and availability of the operating system and its hardware environment such as crash data files.

Other usefull commands -- ps, top, sar, uptime, etc.

Regards,
Ross

You can always run the sys_check utility which gathers information about all the system and put it in a nice format.
You have to install it if it is not there on your system already.
There is a parameter to let it run to gather performance data
use this command
# sys_check -perf

Also, look at the man pages
# man sys_check

Thank's both,
Do you know where could I download the SAR command to install in the server?
Regards.

In 5.1, I think SAR is on one of the
two associated product CDs that come with the OS kit.
The kit name should be ESVFBIN100 for binaries and ESVFMAN100 for the man pages
Hopefully you can find it

For long term performance, my recommendation is the COLLECT mentioned earlier. It is by far the best tool, but you need to learn it for a short while. The optional 'sar' tool is of course relatively well known.

For short term performance monitorring, my preferred tool is 'monitor'.
It is sort of a 'top' whithout processes.
It should memory, cpu, disk, net, all in one dynamic page.

Also, with 'collect' there's the 'collgui' utility that allows you to produce graphs. You have to install it using the 2nd Associated Products CD.
