SYNOPSIS

catsafiles [-d day] [-x]* [-X]*

DESCRIPTION

Given a modified (see below) /usr/lib/sa/sa1 file that will write hourly sar data to
/var/log/sa/sa<mm><HH> this script will cat the hourly files together
into a single (and expected by sar) daily file. This is necessary because
the Mac OS X sadc data collector will truncate the daily file every time
it is run (instead of appending to it as is normal in Solaris). While data could
be collected on a daily basis, the problem is that the rest of a day’s data collection
will be lost due to a crash or restart of the machine, as opposed to just the rest
of the current hour’s data.
Note:
The following change was made to /usr/lib/sa/sa1:
    diff sa1.orig sa1
        26c26
        < DATE=‘/bin/date +%d‘
        ---
        > DATE=‘/bin/date +%d%H‘

The following change was made to /usr/lib/sa/sa2 (plus a change to keep the files longer):
    diff sa2 sa2.orig
        26c26
        < DATE=‘/bin/date +%d%h‘
        ---
        > DATE=‘/bin/date +%d‘
        33c33
        < /usr/bin/find /var/log/sa \( -name ’sar??’ -o -name ’sa??’ \) -mtime +27 -exec /bin/rm -f {} \;
        ---
        > /usr/bin/find /var/log/sa \( -name ’sar??’ -o -name ’sa??’ \) -mtime +7 -exec /bin/rm -f {} \;

OPTIONS

-d day	specify an alternative day instead of today (2 digits) (default=‘date +%d‘)
-x	does ’set -x’ (may be used in functions and external script calls) (see DIAGNOSTICS below)
-X	sets debugging level--the number of times -X is specified" (see DIAGNOSTICS below)
