Для парсинга почтового лога используется утилита pflogsumm

# apt-get install pflogsumm

1	# apt-get install pflogsumm

# yum install postfix-perl-scripts

1	# yum install postfix-perl-scripts

# pflogsumm /var/log/mail.log -d today

1	# pflogsumm /var/log/mail.log -d today

Скрипт предусматривает кеш, что позволяет избежать парсинга лога на каждый параметр. Время действия кеша (TTLCACHE) в секундах должно устанавливается чуть меньше чем минимальный период опроса элементов.(в скрипте установлен кеш 1740 секунд, […]

1.Установка скрипта

# mkdir /etc/zabbix/scripts/

1	# mkdir /etc/zabbix/scripts/

# chown root:zabbix -R /etc/zabbix/scripts/

1	# chown root:zabbix -R /etc/zabbix/scripts/

Установка прав

# chown root:zabbix /etc/zabbix/scripts/lmsensors.sh

1	# chown root:zabbix /etc/zabbix/scripts/lmsensors.sh

# chmod 550 /etc/zabbix/scripts/lmsensors.sh

1	# chmod 550 /etc/zabbix/scripts/lmsensors.sh

Скрипт поддерживает обнаружение (discovery) процессоров. Необходимо установить пакет lm-sensors В зависимости от дистрибутива

# yum install lm_sensors

1	# yum install lm_sensors

# apt-get install lm-sensors

1	# apt-get install lm-sensors

Core 0: +100.0°C (high = +100.0°C, crit = +100.0°C)

Проверяем работу скрипта

# sudo -u zabbix /etc/zabbix/scripts/lmsensors.sh none CPU0

1	# sudo -u zabbix /etc/zabbix/scripts/lmsensors.sh none CPU0

2.Настройка Zabbix-агента

# nano /etc/zabbix/zabbix_agentd.conf

1	# nano /etc/zabbix/zabbix_agentd.conf

### CPU Temperature
UserParameter=lmsensors[*],/etc/zabbix/scripts/lmsensors.sh "none" $1

1 2	### CPU Temperature UserParameter=lmsensors[*],/etc/zabbix/scripts/lmsensors.sh "none" $1

Перезапуск агента

# service zabbix-agent restart

1	# service zabbix-agent restart

Проверка –выполняем команду на Zabbix-сервере

# zabbix_get -s <IP-address-Zabbix-агента> -k "lmsensors[CPU0]"

1	# zabbix_get -s <IP-address-Zabbix-агента> -k "lmsensors[CPU0]"
