go-httpstat
is a golang package to trace golang HTTP request latency (DNSLookup, TCP Connection and so on). Because it uses httptrace
internally, just creating go-httpstat
powered context
and giving it your http.Request
kicks tracing (no big code modification is required). The original idea came from httpstat
command ( and Dave Cheney's golang implementation) 👏. This package now traces same latency infomation as them.
See usage and example on GoDoc.
NOTE: Since httptrace
was introduced after go1.7, this package may not work with old HTTP client. Especially, if you don't use net.DialContext
it can not trace DNS and connection.
