OSF/DU Managers,
I am submitting this request on behalf of a colleague who does not (yet)
subscribe to this list. Please reply either to myself or directly to him,
marc_at_osm.co.uk. Many thanks. The request reads:
I have a question about the validity of data in the OSF/1, sorry Digital UNIX,
process accounting file (usually /var/adm/pacct). The ac_io value (see
/usr/include/sys/acct.h) seems to have a number of ranges.
The effect seems to show itself for most commands, i.e. processes. A way to
show it is to use
acctcom -i -n pwd
(or "ls" or "mv" etc. instead of "pwd") and look at the "CHARS TRNSFRD"
column. On both machines I have tried this on, the value is either ~330k
or ~17.3M. On one, there was also a set of ~22M.
The values seem to depend, at least partially, on the display environment.
Running a command directly within an xterm usually results in a large value,
whereas a command run via, say, a telnet session, usually gives a small value.
Of course, much more processing and library code is involved with an xterm,
but even so the values seem a bit extreme.
Are the values being corrupted? They are stored in the compressed "comp_t"
format, but this seems to work for all other flavours of UNIX I have
encountered. The effect shows itself on OSF/1 3.0 and 3.2, and presumably all
other 3.*.
Can anyone shed any light on this?
Marc
