日志下载地址 https://pan.baidu.com/s/1hwBTtRjuS49L7TfVs_4o7g?pwd=f8qe 上述为服务器 Nginx 日志,关键信息被脱敏,日志格式如下 '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" "$http_user_agent" ' '"$http_x_forwarded_for" "$http_x_real_ip" "$host" ' '"$server_name" $server_port ' '$upstream_cache_status "$upstream_addr" "$upstream_status" "$upstream_response_time" ' '$request_length $request_time $remote_port ddd 通过 Linux 分析可以看到超时请求 cat xxx.log|awk '{log_time=substr($4, 2); match($0, /timestamp=([0-9]+)/, arr); given_timestamp = arr[1];; cmd="date -d \"$(echo "log_time" | sed \"s/\\// /g\" | sed \"s/2025:/2025 /\")\" +%s"; cmd | getline log_timestamp; close(cmd); diff=log_timestamp-given_timestamp; if(diff<0) diff=-diff; if(diff >4) print diff, $0}' 通过分析发现,大约 10%左右超时,怀疑是微信服务器到业务服务器链路存在问题
微信报警问题排查?我是在沈阳区域的公众号开发者,从 1 月 6 号开始,分析微信的回调地址发现有 12% 左右的超时,原先的出口为联通出口,后更换为移动出口仍然是相同情况,我怀疑微信的服务器出现繁忙导致回调超时,以下是我记录的微信回调 IP,左侧是出现超时的次数, ``` 435 49.235.43.218 472 175.24.213.149 484 81.69.103.37 506 81.69.103.163 512 81.69.103.129 515 124.222.246.206 517 124.223.151.119 521 42.192.0.152 533 175.24.211.4 535 175.24.211.142 542 122.51.51.45 547 110.40.132.164 554 175.24.214.222 556 81.69.101.237 557 1.15.77.182 557 118.25.155.162 558 81.69.103.74 563 42.192.6.57 565 175.24.212.185 565 42.192.0.224 567 81.69.103.205 573 81.69.101.233 575 111.231.165.30 580 175.24.212.10 583 175.24.211.31 590 81.69.103.147 592 175.24.211.157 595 175.24.211.198 599 122.51.55.51 601 81.69.103.238 616 1.116.119.192 620 81.69.103.236 626 175.24.214.150 634 124.223.33.44 667 81.69.101.193 728 175.24.212.195 ``` 我的超时分析流程如下: 服务器记录的访问地址为`175.24.211.198 - - [13/Mar/2025:00:02:24 +0800] "POST /xxxxxx/wechatserver?signature=xxxxxx×tamp=1741795338&nonce=xxxx&openid=oxxxxx&e ncrypt_type=aes&msg_signature=xxxxxx HTTP/1.1" 200 17 "-" "Mozilla/4.0" "-" "-" "xxxx.xxxxx.com" -"0.036" 1441 0.037 42298`,通过分析1741795338和访问时间 `13/Mar/2025:00:02:24` 的差值,如果相差超过 5 秒,则记录为超时
