David,
You are correct in how the logs roll over. On Unix/Linux logs, to find the
end of the log you can search for <END OF LOG FILE>. Everything after that is
earlier than what is above it.
It sounds like the new config option makes the regular logs work like the newer
java logs (where you can keep a set number of logs.
I have a script that I use thru cron (task scheduler in Windows) that I use to
save my log files every 10 minutes. Doing so allows me to keep an entire day's
worth of log files for debugging and support.
#! /usr/bin/ksh

if [ -z "$ARCONFIGDIR" ]
then
ARS_ROOT=/opt/ars
ARCONFIGDIR=${ARS_ROOT}/ars
AR_TMP_DIR=${ARCONFIGDIR}/tmp
AR_LOG_DIR=${ARCONFIGDIR}/Logs
fi
#
cur=`date +%H%M`
# Set the location of the existing files and where to save them
logpath=${AR_LOG_DIR}
savpath=${AR_LOG_DIR}/save15
# Make sure log files are readable by everyone with access to server
cd $ARCONFIGDIR/db
chmod a+r *.log
cd $logpath
chmod a+r *.l*
#
[ -r arsql.log ] && cp arsql.log ${savpath}/arsql_${cur}.log ;
[ -r arfilter.log ] && cp arfilter.log ${savpath}/arfilter_${cur}.log ;
[ -r arapi.log ] && cp arapi.log ${savpath}/arapi_${cur}.log ;
#
cd ${savpath}
#
rm -f *${cur}.log.gz > /dev/null
gzip *${cur}.log
#
exit 0
Basically it works like this:
Check for the environment variable ARCONFIGDIR. If it is not there set up
the base environment variables for use.
Set a variable for the hour and minute. All saved files will be in the
format of file_HHMM.log
Set the location of the existing files and where to save them
Make sure log files are readable by everyone with access to server
If the file exists copy it
Remove yesterday's file(s)
Compress todays new files

Susan,
As far as your comment about keeping logs running, maybe you know, but you can
already do that on 7.5 by setting the Maximum Log-File Size in the Server Admin
form. When looking at the files in that case, you have to keep in mind that
when the max size is reached, it starts writing over at the top of the file.
(At least that’s behavior for us - I think we have Create Backup selected.) So
you might have entries in the bottom part with timestamps before the top part –
can be confusing if one doesn’t keep that in mind.

That's more clear to me now. We're still at 7.5 so I guess we'll look at the
next version that comes out for an upgrade hopefully next year.
Thanks for the info Andrew and Ravi !

It is going to help so much in working with support. Can’t tell you how many
times a log has been unworkable or useless because it has rolled over itself
due to the fixed size “readable” limit, even 0 limit will stop at 2gb – not
that is readable/manageable anyway
Max-Log-History: 3
Sql.log <- current log
Sql.001.log ← oldest generation
Sql.002.log
Sql.003.log ← latest generation /rolled log

Hi Andrew,
Not sure what 'generational' logging is. Are you referring to a rolling log,
where you could set a max and then oldest entries drop off when the max size is
reached to make room for new entries? That would be great to have some logs
continually running for those unexpected times when you'd like to look at
something that happened but the logs weren't on.
Regards,
Susan

I’ve been wanting generational logging in ARS for a long time.
I just learned that is now available with a new ar.cg parameter Max-Log-History
I don’t know when this was implemented, maybe it was with 7.6.x but I wish BMC
would have advertised this to admins or made this accessible on the Server
Information Tab.
e.g. Max-Log-History: 20
