Regex 如何从系统日志中检索键和值？

我试图从syslog解析日志，但我有一些疑问和困难找到一个合适的正则表达式

下面是一些示例日志，特别是我需要检索每行的POWER、LoadAvg等值

您是否打算使用纯linux（如sed、grep）或某种语言来实现这一点？我认为在大多数语言中，您可以使用命名组，如：

\"LoadAvg\":(?P<loadAvg>\d+?),\"POWER\":\"(?P<power>.+?)\"

“LoadAvg\”：（？P\d+？），“POWER\”：“（？P+？）”

“LoadAvg\”：（？P\d+？），“POWER\”：“（？P+？）”

使用带有选项

-p

（Perl）和

-o

（仅匹配）的

grep
