Statspack: Segregation of non-application workload

Question

Hello,
Oracle 10.2.0.5.0 (32 bit)
Windows 2003 R2 Standard Edition
I have statspack running at 30 minute interval on this database. I am interested in finding details of the "physical write total bytes" part.
Statistic                                      Total     per Second    per Trans
physical write bytes                      25,444,352       14,135.8      2,276.7
physical write total bytes               121,980,928       67,767.2     10,914.5As one can see, the difference is huge (I am assuming the unit for "Total" column, for these statistic, is bytes).
The documentation (http://docs.oracle.com/cd/B19306_01/server.102/b14237/stats002.htm) says
<quote>
Physical write total bytes
Total size in bytes of all disk writes for the database instance including application activity, backup and recovery, and other utilities. The difference between this value and "physical write bytes" gives the total write size in bytes by non-application workload.
<quote>
Since the non-application workload seems to be higher than the application workload, I am curious if we can get an actual break down of the number of bytes (operation wise) for all non-application related operations.
Thanks in advance,
Regards,

Satish,
Logminer, Listner log, auditing, Tanel Podder's [url http://tech.e2sn.com/oracle-scripts-and-tools/session-snapper] snapper , triggers can be used to get an idea how much redo (no. of blocks and bytes) has been generated for a given transaction; something like suppose I wish to get how much redo will generate if I says : update scott.emp set empno=somevalue where empno=queryvalue. If this is your question, which seems correct to me, because the value of redo generation per transaction; I think Its application workload on db. I am sure, you all these knows, but just re-mentioning in the light of question or something rephrasing the question please.
While googling with "application workload analysis for oracle database", I thought there may be another, but totally different and separate tools of either oracle and/or third party by which we can capture actual workload analysis data by chart, html pages, something like Oracle 12c Enterprise Manager. I am reading [url http://www.oracle.com/technetwork/oem/pdf/511991.pdf] this  pdf, which is saying "
"Capturing Application Workload Using RUEI
In order to capture the application workloads, Oracle Application Replay uses Oracle Real User Experience Insight (RUEI). RUEI is a Web-based utility for monitoring and reporting on real-user’s experience with your Weband packaged applications. It measures the response times of pages, issues users are experiencing, if issues are application or network related,user flows and much more.. It provides you with powerful analysis of your network and business infrastructure, while an insightful diagnostics facility allows application managers as well as IT technical staff to perform root-cause analysis."
But yes, I think Oracle should incorporate an option/switch to segregate the total application bytes in statspack in next release/patch or a portion in which we can see the application workload and non-application workload something like this :
Application Name     Total Blocks      Total Bytes      CPU Consumption%      SGA Usages%

App2.ExeRegards
