Я пытаюсь заставить munin уведомить меня по электронной почте. Я настроил munin, и он сообщает о критических значениях и предупреждениях, но никакие предупреждения не отправляются, и не вызывается какой-либо скрипт. Не могли бы вы помочь мне с этим?
Я включил часть munin.conf ниже
# Drop somejuser@fnord.comm and anotheruser@blibb.comm an email everytime
# something changes (OK -> WARNING, CRITICAL -> OK, etc)
#contact.someuser.command mail -s "Munin notification" somejuser@fnord.comm\
contact.prashanth.command echo "Munin notification" | sendmail -t xxx@xxx.net
contact.prashanth.always_send warning critical
contact.root.command echo "Munin notification" | sendmail -t xxxl@xxx.net
contact.root.always_send warning critical
contact.pipevia.command | /home/prashanth/script.sh /home/prashanth/script.sh
Ничего из этого не работает. Вот журнал munin-limits.log

2011/09/26 14:58:12 [INFO] munin-limits finished (0.02 sec)
2011/09/26 14:58:12 Command "prashanth" stderr: Munin notification - this is a test mail from the user prashanth | sendmail -t xxx@xxx.net
Что мне здесь не хватает и почему не отправляются электронные письма?
Вам нужно настроить Munin для отправки предупреждений. Если оба пункта не установлены, письма отправляться не будут. Вот как я настроил Munin для отправки электронной почты через localhost на машине, на которой работает Мунин. Пожалуйста, сравните с тем, что у вас есть, и отрегулируйте соответственно:
contact.myalert.command mail -s "MUNIN - ${var:group} :: ${var:host}" mymail@domain.com
contact.myalert.always_send warning critical
И затем под деревом хоста у меня есть эта настройка. Обратите внимание contacts myalert линия:
# a simple host tree
[localhost.localdomain]
address 127.0.0.1
use_node_name yes
contacts myalert
Похоже, ваша конфигурация не соответствует примеру из файла munin.conf. Пример такой:
contact.someuser.command mail -s "Munin notification" somejuser@fnord.comm
И у тебя есть:
contact.prashanth.command echo "Munin notification" | sendmail -t xxx@xxx.net
Я ожидал, что что-то вроде этого сработает:
contact.prashanth.command mail -s "Munin notification" xxx@xxx.net
У меня была такая же проблема, похоже, проблема с цитированием, у меня сработало следующее:
contact.prashanth.command 'echo "Munin notification" | sendmail -t xxx@xxx.net'
