Hi Scott,
Yes, the records are identical. After a SORT UNIQUE the duplicate
records are discarded. The only thing that is not identical is the TOD
field. The second (and third) record are produced a few miliseconds
after the first. When I discard the miliseconds the records themselves
are truly identical. That leads me to believe that these are seperatly
created records.
The record produced by the TCPIP stack contains data from the OSA
device, we are interested in the number of bytes in and out for the
device during the minute interval.
As I understand it there is a buffer for each device. So the OSA devices
each have a record and the CTC devices also have a record. And indeed
that is what we get on other LPARs. Only on this particular LPAR we have
more than one record. And only for the OSA's, not for the CTC's.
Regards, Berry.

Just poking around found this description of the monitor record:
DESCRIPTIVE NAME - Monitor Sample Record
Domain 10 - Appldata domain
Record 2 - Application Data Sample Record
DESCRIPTION - Application data as found in the application-defined
buffer at the time of this sample interval. A
separate record is generated for each buffer
declared by the virtual machine(s) via the Diagnose
'DC' START operation.
Seems to imply a separate record is generated for each buffer declared.. I'm
not sure what the application data sample is in this case. Are the records
truly duplicates? (the whole record is absolutely identical, displayable chars
or not) Perhaps the application data needs to be appended to come up with the
entire field?

Hi listers,
I am looking at processing the userrecords in the CP MONITOR for
the TCPIP
stacks. These are in CP MONITOR domain 0A record 02. The data is
collected
though a STARMON stage, basically "PIPE STARMON | locate
<selection> | >
fielid".
Most LPARs have records like I'd expect them but I have found that
in one
LPAR we have duplicate records for subrecordtype 05 for each of
the the OSA
devices.
The CTC's for VSE systems have one record per minute for each VSE
system.
The OSA links have 2 identical records (apart from a slight
difference in
timestamp, a few miliseconds apart). A second IP stack even writes
3 records
for every minute.
So basically we see:
00:01 VSE1
00:01 VSE2
00:01 OSA1
00:01 OSA2
00:01 OSA1
00:01 OSA2
00:02 ...
What can cause the CP monitor to have these duplicate records?
TIA, Berry.
