This article will continue to summarize some of the methods of memory, GC metrics

The first is through

Stats:= &Runtime.Memstats{}Runtime.Readmemstats(Stats)

This is to get a stat that contains information about memory and garbage collection: GC Time distribution SLICE,GC Total time, GC number, etc.

typeGarbage struct{aint }func Notify(F*Garbage) {Stats:= &Runtime.Memstats{}Runtime.Readmemstats(Stats)FMT.Println("Last GC was:",Stats.LASTGC)

GoProducefinalizedgarbage()}funcProducefinalizedgarbage() {x:= &Garbage{}Runtime.Setfinalizer(x,Notify)}Func main() {GoProducefinalizedgarbage()     for {Runtime.GC() Time.Sleep( - * Time.Second) //Give GC time to run    }}
