在nginx配置中,经常看到request time,upstream response time,有些时间并不是很清楚二者的差异,感觉差不多,其实: 本质是requst time是从client发起请求到返回结果的时间 而upstream response time是nginx建立连接到返回结果的时间,固然中间的时间是网络开销的时间,所以一般来说requset time大,而接口的相应时间慢的话 ...

笔者在根据nginx的accesslog中$request_time进行程序优化时,发现有个接口,直接返回数据,平均的$request_time也比较大。原来$request_time包含了用户数据接收时间,而真正程序的响应时间应该用$upstream_response_time。 下面介绍下 ...
nginx常见的2个time 我们在通过tsar采集对nginx的数据进行采集时,发现tsar采集到的rt时间和nginx自身日志中打印的时间$request_time对不上,这让我们在收到报警后很难快速的和nginx的日志对应起来,从而找到我们响应慢的api。于是对nginx的几个处理时间 ...

下图是request_time。 下图是upstream_response_time. 精准的描述就是:request_time是从接收到客户端的第一个字节开始,到把所有的响应数据都发送完为止。upstream_response_time是从与后端建立TCP连接 ...
首先,澄清一个误区 upstream_response_time必须在upstream配置时才能使用? 答案: 否。 举例: request_time 官网描述:request processing time in seconds with a milliseconds ...
设置log_format,添加request_time,$upstream_response_time,位置随意 og_format main '"$request_time" "$upstream_response_time" $remote_addr - $remote_user ...
