Munin-如何从插件返回未知值

[英]Munin - how to return unknown value from plugin

原文 2012-09-27 09:04:36 4 1 plugins/ ntp/ munin

I want my munin plugin to report unknown values if the value can't be reported. 我希望我的munin插件能够报告未知值（如果无法报告该值）。 What do I have to return? 我要退还什么？

"nan" “南”
"-nan" “ -nan”
nothing at all, just skip returning a value 什么都没有，只是跳过返回值
"unknown" “未知”
...? ...？

Nothing works for me. 什么都不适合我。

Background: ntp_offset plugin fails if ntp is not running at all. 背景：如果ntp根本没有运行，则ntp_offset插件将失败。 I want to return unknown value and send an alert message. 我想返回未知值并发送警报消息。

1 个解决方案

I think the correct value to return is "U". 我认为要返回的正确值是“ U”。
