 description: Pingap 请求日志格式化
 ---
 
-Pingap格式化相关参数，具体参数说明如下：
+Pingap格式化可以使用以下几种默认形式`combined`，`common`，`short`以及`tiny`。也可自定义完整的日志格式化输出，具体参数说明如下：
+
+- `{host}`: 请求的host属性
+- `{method}`: 请求的method
+- `{path}`: 请求的路径
+- `{proto}`: 协议类型，`HTTP/1.1`或`HTTP/2.0`
+- `{query}`: 请求的querystring
+- `{remote}`: 请求的源ip
+- `{client-ip}`: 客户ip，根据`x-forwarded-for`中获取
+- `{scheme}`:
+- `{uri}`: 请求的完整地址
+- `{referer}`: 请求头中的referer
+- `{user-agent}`: 请求的user-agent
+- `{when}`: 日志的输出时间
+- `{when-utc-iso}`: 日志的输出的utc时间
+- `{when-unix}`: 日志的输出时间，格式为时间戳
+- `{size}`: 响应数据的字节数
+- `{size-human}`: 响应数据的大小，按数据大小格式化字符串
+- `{status}`: 响应状态码
+- `{latency}`: 响应时间的ms
+- `{latency-human}`: 响应时间，按时间格式化
+- `{payload-size}`: 请求数据的字节大小
+- `{payload-size-human}`: 请求数据的大小，按数据大小格式化字符串
+- `{~cookiename}`: 从cookie中获取对应的值
+- `{>requestHeaderName}`: 请求头中获取对应的值
+- `{<responseHeaderName}`: 响应头中获取对应的值
+- `{:contentName}`: 从context中获取对应的值，暂时仅支持以下属性：`reused`, `upstream-address`, `processing`
+- `{$envName}`: 从环境变量中获取对应的值，仅启动时获取
