istio-proxy访问日志是什么意思? [英] What is istio-proxy access log mean?

问题描述

我正在尝试通过查看istio-proxy访问日志(它记录每次访问)来对我的服务进行故障排除.但是，我找不到任何说明日志中每个条目含义的文档.

I am trying to troubleshoot my service by looking at the istio-proxy access log (it logs every access). However, I can't find any documentation that explains the meaning of each entry in the log.

例如

[2018-12-20T11:09:42.302Z]"GET/HTTP/1.1" 200-0 614 0 0"10.32.96.32""curl/7.54.0""17b8f245-af00-4379-9f8f-a4dcd2f38c01 " foo.com" 127.0.0.1:8080"

[2018-12-20T11:09:42.302Z] "GET / HTTP/1.1" 200 - 0 614 0 0 "10.32.96.32" "curl/7.54.0" "17b8f245-af00-4379-9f8f-a4dcd2f38c01" "foo.com" "127.0.0.1:8080"

上面的日志是什么意思?

What does log above mean?

我尝试了 Vadim的答案，但找不到日志格式数据.这是输出json文件.我有什么想念的吗? 我正在使用istio-1.0.0

I've tried Vadim's answer, but I couldn't find the log format data. Here's the output json file. Is there anything that I miss? I am using istio-1.0.0

推荐答案

Istio/Envoy访问日志带有默认格式. 这是默认格式

Istio/Envoy access logs comes with a default format. Here is the default format

[%START_TIME%] "%REQ(:METHOD)% %REQ(X-ENVOY-ORIGINAL-PATH?:PATH)% %PROTOCOL%" %RESPONSE_CODE% %RESPONSE_FLAGS% %BYTES_RECEIVED% %BYTES_SENT% %DURATION% %RESP(X-ENVOY-UPSTREAM-SERVICE-TIME)% "%REQ(X-FORWARDED-FOR)%" "%REQ(USER-AGENT)%" "%REQ(X-REQUEST-ID)%" "%REQ(:AUTHORITY)%" "%UPSTREAM_HOST%"\n

它与您提供的示例日志条目匹配.您可以找到有关字段的详细信息，以及有关特使访问日志的一般信息，

It matches with the sample log entry that you have given. You can find more details about the fields and generally about envoy's access logs here
