I use the following combination of crontab and script to rename and
produce a calamaris report
# Rotate squid logs
0 4 * * * /usr/sbin/squid -k rotate
# And generate report of freshly rotated log
5 4 * * * /usr/local/bin/Daily_Calamaris
Daily_Calamaris:
#!/bin/bash
WHEN=`/bin/date -d yesterday +%Y%m%d`
LOGDIR="/var/spool/squid"
OUTDIR="/var/spool/squid"
LOGFILE="${LOGDIR}/squid_access.log.0"
NEWFILE="${LOGDIR}/squid_access.log.${WHEN}"
OUTFILE_TXT="${OUTDIR}/squid_report_${WHEN}.txt"
OUTFILE_HTML="${OUTDIR}/squid_report_${WHEN}.html"
/bin/mv ${LOGFILE} ${NEWFILE}
/usr/bin/nice -n 19 \
/bin/cat ${NEWFILE} | \
/usr/bin/calamaris -a -n --domain-report 50 \
--requester-report 100 > ${OUTFILE_TXT}
/usr/bin/nice -n 19 \
/bin/cat ${NEWFILE} | \
/usr/bin/calamaris -F html -a -n --domain-report 50 \
--requester-report 100 > ${OUTFILE_HTML}
- -------------------------------------------------
What Adrian is asking for could be done with something like (is there a
better way to get the time string than using perl?)
#!/bin/bash
LOGDIR="/var/spool/squid"
OUTDIR="/var/spool/squid"
LOGFILE="${LOGDIR}/squid_access.log.0"
FROM=`head -1 ${LOGFILE} | cut -d. -f1 | perl -e \
'($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = \
localtime(<STDIN> - 4 * 60 * 60 ); \
printf("%04d:%02d:%02d-%02d:%02d:%02d\n", \
$year+1900, \
$mon+1, \
$mday, \
$hour, \
$min, \
$sec)'`
TO=`tail -1 ${LOGFILE} | cut -d. -f1 | perl -e \
'($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = \
localtime(<STDIN> - 4 * 60 * 60 ); \
printf("%04d:%02d:%02d-%02d:%02d:%02d\n", \
$year+1900, \
$mon+1, \
$mday, \
$hour, \
$min, \
$sec)'`
NEWFILE="${LOGDIR}/squid_access.log.${FROM}--${TO}"
OUTFILE_TXT="${OUTDIR}/squid_report_${FROM}--${TO}.txt"
OUTFILE_HTML="${OUTDIR}/squid_report_${FROM}--${TO}.html"
/bin/mv ${LOGFILE} ${NEWFILE}
/usr/bin/nice -n 19 \
/bin/cat ${NEWFILE} | \
/usr/bin/calamaris -a -n --domain-report 50 \
--requester-report 100 > ${OUTFILE_TXT}
/usr/bin/nice -n 19 \
/bin/cat ${NEWFILE} | \
/usr/bin/calamaris -F html -a -n --domain-report 50 \
--requester-report 100 > ${OUTFILE_HTML}
- ----------------
Note that the server is in timezone GMT-4, and the server is using UTC,
that's why (a) the crontab runs at 4 am (midnight local time) and (b) I
have to compute the localtime for <STDIN> - 4 * 60 * 60.
Hope it helps

A: Because it destroys the flow of conversation.
Q: Why is top posting dumb?
