Python脚本监控Linux用户CPU使用率

【Python脚本监控Linux用户CPU使用率】实现功能:启动后自动运行,每秒打印一次用户CPU使用率,结束脚本时自动计算并打印平均值和最大值。

#!/usr/bin/python # -*-coding: utf-8 -*-import subprocess import os import timecmd = "top -bn 1 | grep 'Cpu(s)' | awk -F'[\" \"%]+' '{print $3}'"count = 0 total = 0.0 max_use = 0.0try: while True: cpu_usage = os.popen(cmd).readline().strip() count = count + 1; cpu_use = float(cpu_usage) total = total + cpu_use max_use = max(max_use, cpu_use) cpu_tip = "user CPU:" + cpu_usage + "%" print(cpu_tip) time.sleep(1) except KeyboardInterrupt: if count != 0: per = total / count print("user CPU per:" + str(per)) print("user CPU max: " + str(max_use))
