go: 打印ubuntu下的进程cpu 内存占用 直接使用gopsutil这个包，非常的方便 ``` package main import ( "github.com/dalianzhu/logger" "github.com/shirou/gopsutil/process" "sort" "time" ) type processNameCpu struct { Name string Cpu float64 Mem float32 } func main() { logger.InitLogging(logger.FILE, "cpus.log", "/home/log", 2, logger.INFO) for { syspros, _ := process.Processes() pros := make([]*processNameCpu, 0, 100) for _, pro := range syspros { name, _ := pro.Name() percent, _ := pro.CPUPercent() mem, _ := pro.MemoryPercent() pros = append(pros, &processNameCpu{name, percent, mem}) } // 按cpu排序，取前20名打印 sort.Slice(pros, func(i, j int) bool { return pros[i].Cpu > pros[j].Cpu }) for _, pro := range pros[:20] { logger.Infof("%v %v %v", pro.Name, pro.Cpu, pro.Mem) } logger.Infoln("**********************") time.Sleep(time.Second * 2) } } ``` 来自 大脸猪 写于 2019-12-30 17:19 -- 更新于2020-10-19 13:06 -- 0 条评论
