Curl命令行分析本地到服务器的网络访问情况

1、Curl_file文件内容【自定义文件名，包含需要分析的变量字符串】

[root@test ~]# cat  curl_file
time_total: %{time_total}\n
time_connect: %{time_connect}\n
time_starttransfer: %{time_starttransfer}\n
time_namelookup: %{time_namelookup}\n
time_appconnect:  %{time_appconnect}\n
time_pretransfer: %{time_pretransfer}\n
time_redirect: %{time_redirect}\n
speed_download: %{speed_download}\n
speed_upload: %{speed_upload}\n
size_download: %{size_download}\n
size_upload: %{size_upload}\n
size_request: %{size_request}\n
size_header: %{size_header}\n
content_type: %{content_type}\n
ssl_verify_result: %{ssl_verify_result}\n
url_effective: %{url_effective}\n
local_ip: %{local_ip}\n
local_port: %{local_port}\n
remote_ip: %{remote_ip}\n
remote_port: %{remote_port}\n
num_connects: %{num_connects}\n
num_redirects: %{num_redirects}\n
filename_effective: %{filename_effective}\n
http_connect: %{http_connect}\n
http_code: %{http_code}\n
response_code: %{response_code}\n
remote_ip: %{remote_ip}\n
remote_port: %{remote_port}\n
ftp_entry_path: %{ftp_entry_path}\n

2、服务器curl请求命令

[root@test ~]# curl  -o  /dev/null  -s   -w @curl_file   https://www.baidu.com
time_total: 0.338
time_connect: 0.061
time_starttransfer: 0.338
time_namelookup: 0.004
time_appconnect:  0.281
time_pretransfer: 0.281
time_redirect: 0.000
speed_download: 7219.000
speed_upload: 0.000
size_download: 2443
size_upload: 0
size_request: 77
size_header: 400
content_type: text/html
ssl_verify_result: 0
url_effective: https://www.baidu.com/
local_ip: 172.30.0.8
local_port: 56352
remote_ip: 182.61.200.7
remote_port: 443
num_connects: 1
num_redirects: 0
filename_effective: /dev/null
http_connect: 000
http_code: 200
response_code: 200
remote_ip: *.*.*.*
remote_port: 443
ftp_entry_path:

或者不读取文件，仅一条命令获取请求结果：

[root@test ~]# curl  -o  /dev/null  -s   -w  " time_total: %{time_total}\n time_connect: %{time_connect}\n time_starttransfer: %{time_starttransfer}\n time_namelookup: %{time_namelookup}\n time_appconnect:  %{time_appconnect}\n time_pretransfer: %{time_pretransfer}\n time_redirect: %{time_redirect}\n speed_download: %{speed_download}\n speed_upload: %{speed_upload}\n size_download: %{size_download}\n size_upload: %{size_upload}\n size_request: %{size_request}\n size_header: %{size_header}\n content_type: %{content_type}\n ssl_verify_result: %{ssl_verify_result}\n url_effective: %{url_effective}\n local_ip: %{local_ip}\n local_port: %{local_port}\n remote_ip: %{remote_ip}\n remote_port: %{remote_port}\n num_connects: %{num_connects}\n num_redirects: %{num_redirects}\n filename_effective: %{filename_effective}\n http_connect: %{http_connect}\n http_code: %{http_code}\n response_code: %{response_code}\n remote_ip: %{remote_ip}\n remote_port: %{remote_port}\n ftp_entry_path: %{ftp_entry_path}\n "   https://www.baidu.com
