collect error?

collect error?

I get statistics disks load by collect command:
collect -i 300 -etlnqmfy >/tmp/collect.txt

And I see high summary load "DISK Statistics" for dsk4 (clolumn %BSY) see .
But per process statistic shown that only one oracle process 40448 write to disk (OBk - 2).

I think, that summary load is incorrect because between 07AM and 08AM i have no transactions, jobs, no other activity in system.

Re: collect error?

What is the OS and patch version?. There were some CPU related fixes that had gone into 'collect', but I don't remember seeing any disk related changes. Anyway, you can try out the latest collect CSP by logging a call with HP support.

Did you try running 'iostat' at the same instance?.

My version is Compaq Tru64 UNIX V5.1A (Rev. 1885).

Re: collect error?

Did you check the 'iostat' output?

Was there any cron job scheduled to running during that time?

Re: collect error?

I got statistics by iostat command.
Values in "bps" column iostat command same as in collect statistic.

I think that in this 5 min starts and ends processes that not listed in collect. This processes works with disks.
I'll check it.

Re: collect error?

What you said could really be true. Is there anything in the cron jobs that could be the culprit?

Re: collect error?

At 04:00 I analyze oracle indexes, after it I think oracle reloads all used indexes into buffer memory.

High load begins after analyze index. What ORACLE do I not see yet.

Re: collect error?

Now I see that 3 days %BSY about 15% :(
There are my "DISK Statistics":
#DSK NAME B/T/L R/S RKB/S W/S WKB/S AVS AVW ACTQ WTQ %BSY
0 dsk4 1/0/0 108 4300 10 103 1.52 0.00 0.18 0.00 14.69

RKB/S + WKB/S = 4300 + 103 = 4403 - Kbytes transfered by disk dsk4.
But "Process Statistics" I see that only 18 blocks reads. How it can be (4403Kb != 18 blocks)?

On weekends must not be any activity. All other disk load about 0-1%.
