我想将 kubernetes 日志输出到文件中。但是,我只能将其输出为 json 数据。我只想将“消息”部分输出到文件。
如何选择“消息”进行打印?我应该选择哪种过滤器?
<match output_tag>
@type rewrite_tag_filter
<rule>
key $['kubernetes']['labels']['app']
pattern ^(.+)$
tag app.$1
</rule>
</match>
<match app.tom1>
@type file
path /logs/tom1
</match>
Execute result:--->
2019-10-30T00:46:05+09:00 app.tom1 {
..
"message": "2019-10-29 15:46:05,253 DEBUG [org.springframework.web.servlet.DispatcherServlet] Successfully completed request",
"kubernetes": {
"labels": {
"app": "tom1",
..
}
Desired result: --->
2019-10-29 15:46:05,253 DEBUG [org.springframework.web.servlet.DispatcherServlet] Successfully completed request
感谢!
