Automatically profile the Go applications when CPU or memory utilization crosses threshold levels.
Once you start the autopprof, the autopprof process will periodically check the CPU and memory utilization of the Go applications. If the resource utilization crosses the specified threshold for each type of resource, the autopprof will automatically profile the application (heap or cpu) and report the profiling report to the specific reporter (e.g. Slack).
Currently, only Memory profiling is supported. We'll add CPU profiling support soon.
go get -u github.com/daangn/autopprofIf your application is running on non-linux systems, you should check the ErrUnsupportedPlatform error returned from
autopprof.Start()and handle it properly.
package main
import (
"errors"
"log"
"github.com/daangn/autopprof"
"github.com/daangn/autopprof/report"
)
func main() {
err := autopprof.Start(autopprof.Option{
MemThreshold: 0.5,
Reporter: report.NewSlackReporter(
&report.SlackReporterOption{
App: "YOUR_APP_NAME",
Token: "YOUR_TOKEN_HERE",
Channel: "#REPORT_CHANNEL",
},
),
})
if errors.Is(err, autopprof.ErrUnsupportedPlatform) {
// You can just skip the autopprof.
log.Println(err)
} else if err != nil {
log.Fatalln(err)
}
defer autopprof.Stop()
// Your code here.
}
