# chmod +x /etc/zabbix/scripts/exim4.sh |
В скрипте указываем корректный путь к Exim-лог файлу в переменной main_log
По умолчанию стоит
|
1 |
main_log=/var/log/exim_mainlog |
Если утилита exipick не установлена в системе (например, на Cpanel-установках), то скачиваем ее с официального сайта и сохраняем под именем /usr/sbin/exipick
|
1 |
# wget -O /usr/sbin/exipick http://jetmore.org/john/code/exipick |
|
1 |
# chmod +x /usr/sbin/exipick |
Проверяем работу утилиты exipick
|
1 |
# exipick -bpu |
2.Настройка привилегий пользователя Zabbix
|
1 |
# visudo |
|
1 |
zabbix ALL=(ALL) NOPASSWD: ALL |
3.Настройка Zabbix-агента
|
1 |
# nano /etc/zabbix/zabbix_agentd.d/userparameter_exim.conf |
|
1 |
UserParameter=exim4[*],/usr/bin/sudo /etc/zabbix/scripts/exim4.sh "$1" |
|
1 |
# service zabbix-agent restart |
4.Настройка Zabbix-сервера
Скачиваем, распаковываем и импортируем шаблон
zabbix2_exim_template.zip
Добавляем шаблон к хосту
Проверяем, что через 1-2 минуты на хосте появились Item с именем Exim
Monitoring->Latest Data->фильтруем по требуемому хосту в поле Hosts->Exim
По умолчанию установлены два триггера:
Warning — при достижении почтовой очереди в 30 писем (макрос шаблона {$EXIM_QUEUE})
High – при достижении почтовой очереди в 60 писем ({$EXIM_QUEUE} *2 )
