Формирование отчетов с использованием sarg

Задача на сегодня стоит следующая - организовать ежемесячный сбор статистики о работе пользователей в интернет с отправкой отчета на email. Предполагается, что squid настроен и работает правильно. :)

Используемая ОС:

# uname -a
FreeBSD srv-home 6.4-RELEASE-p7 FreeBSD 6.4-RELEASE-p7 #0: Sat Oct  3 20:59:38 YEKST 2009 root@home.ru:/usr/obj/usr/src/sys/HAUNTED  i386

Идем в порты ставить sarg:

# cd /usr/ports/www/sarg
# make install clean

Из предложенных опций я ничего не выбрал. После установки идем править конфиг sarg - /usr/local/etc/sarg/sarg.conf. У меня он получился такого содержания:

#!/bin/sh

SARG_BIN="/usr/local/bin/sarg"
SQUID_LOGDIR="/usr/local/squid/logs"
TMPDIR="/var/tmp"

if [ ! -f "${SQUID_LOGDIR}/access.log" ]; then
       echo "Not found squid access.log file"
       exit 1
fi

cp "${SQUID_LOGDIR}/access.log" "${TMPDIR}/squid-access.log"
cat /dev/null > "${SQUID_LOGDIR}/access.log"
${SARG_BIN} -w ${TMPDIR} -l "${TMPDIR}/squid-access.log" > /dev/null 2>&1
rm -f "${TMPDIR}/squid-access.log"

exit 0

Я разместил его в /etc/periodic/monthly/300.sarg-report. Не забываем дать права на исполнение.
Ну и на этом все, можно пользоваться.
