How to use the performance counters? 1

[dafnas]

Hi, Maybe someone can answer this question, I really need to know the answer....
I need to measure D-Cache and E-Cache miss rate on the UltraSparc II and I saw there is a command "cputrack" that can do that.
My question is:
running the command (for example) to measure E-Cache miss rate will be -
cputrack -fev -c EC_ref,EC_hit <command>
The output of this command is many lines, where each line contains the number of cache ref/hit at a tick.
But -what do I do to get the result I want(total miss ratio)? Do I sum all the lines together or do I just look at the final line (where the word &quot;exit&quot; is).

Thanks you very much
Dafna

OK, Feb 21 2002 (long time ago...)
most probably you solved that problem so this answer is for the other ones who suffer on the same thing.
Try &quot;har&quot; instead of &quot;cputrack&quot;.
It's available on

By the way, can you tell me which counters are available on Fujitsu machines?
&quot;cputrack -h&quot; tells about strange counter names &quot;group0, group1...&quot;
Even painful browsing through 60 pages of high tech stuff (SPARC documentation) didn't reveal their meaning and why any(!) other counter cannot be measured.
