Trace is a tool for viewing trace files.
|
||
|
|
|
||
|
|
Trace files can be generated with:
|
||
|
|
- runtime/trace.Start
|
||
|
|
- net/http/pprof package
|
||
|
|
- go test -trace
|
||
|
|
|
||
|
|
Example usage:
|
||
|
|
Generate a trace file with 'go test':
|
||
|
|
go test -trace trace.out pkg
|
||
|
|
View the trace in a web browser:
|
||
|
|
go tool trace trace.out
|
||
|
|
Generate a pprof-like profile from the trace:
|
||
|
|
go tool trace -pprof=TYPE trace.out > TYPE.pprof
|
||
|
|
|
||
|
|
Supported profile types are:
|
||
|
|
- net: network blocking profile
|
||
|
|
- sync: synchronization blocking profile
|
||
|
|
- syscall: syscall blocking profile
|
||
|
|
- sched: scheduler latency profile
|
||
|
|
|
||
|
|
Then, you can use the pprof tool to analyze the profile:
|
||
|
|
go tool pprof TYPE.pprof
|
||
|
