Munin警报/通知未被执行

Question

我有一个自定义通知脚本，我想在发生严重事件时使用来自munin的数据。不幸的是，我无法使其正常工作，同时遵循官方文档。它自己的通知脚本经过测试，并且在使用假数据从shell调用时工作正常。它的权限在755上，所以执行也不应该成为问题。因此，联系挂钩可能未被调用。 我所做的是：

# /etc/munin/munin-conf.d/custom.cnf 
    [...] 
    contact.slack.command MUNIN_SERVICESTATE="${var:worst}" MUNIN_HOST="${var:host}" MUNIN_SERVICE="${var:graph_title}" MUNIN_GROUP=${var:group} /usr/local/bin/notify_slack_munin 
    contact.slack.always_send warning critical 
    contact.slack.text ${if:cfields \u000A* CRITICALs:${loop<,>:cfields ${var:label} is ${var:value} (outside range [${var:crange}])${if:extinfo : ${var:extinfo}}}.}${if:wfields \u000A* WARNINGs:${loop<,>:wfields ${var:label} is ${var:value} (outside range [${var:wrange}])${if:extinfo : ${var:extinfo}}}.}${if:ufields \u000A* UNKNOWNs:${loop<,>:ufields ${var:label} is ${var:value}${if:extinfo : ${var:extinfo}}}.}${if:fofields \u000A* OKs:${loop<,>:fofields ${var:label} is ${var:value}${if:extinfo : ${var:extinfo}}}.} 

上面的节点和目录的定义这些线路工作正常。但通知不会出去。你有什么想法可能是什么？

Answer 1

我只是打了相同的脚本最初发现于gist得到它固定2次琐碎失误后工作：

• 确保你把联系人在配置宿主树前。我把它放在配置文件的末尾，直到我将它移到放置示例联系人的地方为止
• 请确保Munin配置中的命令使用完整的文件名，因此如果您将在/usr/local/bin/notify_slack_munin脚本，然后检查是否有对文件

正如写在Munin Guide没有文件扩展名，看穆宁，limits.log看到发生了什么。

最后注意，如果您有contact.slack.always_send warning critical它将重复推送通知，而不仅仅是严重性更改。

以供参考（如果要点链接刹车），调用松弛网络挂接脚本如下（略有修改澄清）：

#!/bin/bash 

# Slack notification script for Munin 
# Mark Matienzo (@anarchivist) 
# https://gist.github.com/anarchivist/58a905515b2eb2b42fe6 
# 
# To use: 
# 1) Create a new incoming webhook for Slack 
# 2) Edit the configuration variables that start with "SLACK_" below 
# 3) Add the following to your munin configuration before the host tree 
# in the part where sample contacts are listed: 
# 
# # -- Slack contact configuration 
# # notify_slack_munin.sh is the full file name 
# contact.slack.command MUNIN_SERVICESTATE="${var:worst}" MUNIN_HOST="${var:host}" MUNIN_SERVICE="${var:graph_title}" MUNIN_GROUP=${var:group} /usr/local/bin/notify_slack_munin.sh 
# # This line will spam Slack with notifications even if no state change happens 
# contact.slack.always_send warning critical 
# # note: This has to be on one line for munin to parse properly 
# contact.slack.text ${if:cfields \u000A* CRITICALs:${loop<,>:cfields ${var:label} is ${var:value} (outside range [${var:crange}])${if:extinfo : ${var:extinfo}}}.}${if:wfields \u000A* WARNINGs:${loop<,>:wfields ${var:label} is ${var:value} (outside range [${var:wrange}])${if:extinfo : ${var:extinfo}}}.}${if:ufields \u000A* UNKNOWNs:${loop<,>:ufields ${var:label} is ${var:value}${if:extinfo : ${var:extinfo}}}.}${if:fofields \u000A* OKs:${loop<,>:fofields ${var:label} is ${var:value}${if:extinfo : ${var:extinfo}}}.}
