Now, the HTTP Agent only gets the response code (CURLINFO_RESPONSE_CODE), but not other internal information, which is very useful like CURLINFO_TOTAL_TIME, CURLINFO_STARTTRANSFER_TIME, etc.

More Info: https://curl.haxx.se/libcurl/c/curl_easy_getinfo.html

I make a external script in bash to collect this information, with preprocessing get Response code, Start Transfer Time and Total Response Time, with this info we detect performance problems.

Example of external scrip:

CALL:
/usr/bin/curl -w '{"http_code":%{http_code},"size_download":%{size_download},"size_header":%{size_header},"size_request":%{size_request},"size_upload":%{size_upload},"speed_download":%{speed_download},"speed_upload":%{speed_upload},"time_connect":%{time_connect
},"time_namelookup":%{time_namelookup},"time_starttransfer":%{time_starttransfer},"time_appconnect":%{time_appconnect},"time_pretransfer":%{time_pretransfer},"time_redirect":%{time_redirect},"time_total":%{time_total}}' -o /dev/null -s --data-binary "$XML_POST_DATA" -H "Accept-Encoding
: gzip" -H "Content-Type: text/xml" $URL

OUTPUT:
{{{}}
{{      "http_code": 200,}}
{{      "size_download": 154118,}}
{{      "size_header": 184,}}
{{      "size_request": 196,}}
{{      "size_upload": 1106,}}
{{      "speed_download": 21590,}}
{{      "speed_upload": 154,}}
{{      "time_connect": 0.005,}}
{{      "time_namelookup": 0.004,}}
{{      "time_starttransfer": 0.006,}}
{{      "time_appconnect": 0,}}
{{      "time_pretransfer": 0.005,}}
{{      "time_redirect": 0,}}
     "time_total": 7.138
}

This is only an idea.... if HTTP Agent have a new Retrive mode "Internal" and this return all internal information from curl session in JSON format like I paste before, The HTTP Agent are more powerful.

Thanks,
