我正在尝试让 munin 通过电子邮件通知我。我已经配置了 munin，它报告了关键值和警告值，但没有发送警报，也没有调用任何脚本。你能帮我解决这个问题吗？
我在下面包含了 munin.conf 的一部分
# Drop [email protected] and [email protected] an email everytime
# something changes (OK -> WARNING, CRITICAL -> OK, etc)
#contact.someuser.command mail -s "Munin notification" [email protected]\
contact.prashanth.command echo "Munin notification" | sendmail -t [email protected]
contact.prashanth.always_send warning critical
contact.root.command echo "Munin notification" | sendmail -t [email protected]
contact.root.always_send warning critical
contact.pipevia.command | /home/prashanth/script.sh /home/prashanth/script.sh
这些都不起作用。这是 munin-limits.log

我在这里遗漏了什么？为什么电子邮件没有发送？
答案1
您需要设置两项才能让 Munin 发送警报。如果两项均未设置，则不会发送邮件。这是我在localhost运行 Munin 的机器上配置 Munin 发送电子邮件的方式。请与您已有的进行比较并进行相应调整：
contact.myalert.command mail -s "MUNIN - ${var:group} :: ${var:host}" [email protected]
contact.myalert.always_send warning critical
然后在主机树下我有此设置。请注意以下contacts myalert行：
# a simple host tree
[localhost.localdomain]
address 127.0.0.1
use_node_name yes
contacts myalert
答案2
您的配置似乎与 munin.conf 文件中的示例不匹配。示例为：
contact.someuser.command mail -s "Munin notification" [email protected]
你有：
contact.prashanth.command echo "Munin notification" | sendmail -t [email protected]
我希望这样的事情能够发挥作用：
contact.prashanth.command mail -s "Munin notification" [email protected]
答案3
我遇到了同样的问题，似乎是引用问题，以下方法对我有用：
contact.prashanth.command 'echo "Munin notification" | sendmail -t [email protected]'
