python－检测cpu负载

近期研究nagios，特意写了检测cpu负载的python脚本（有借鉴网上资料），顺道练练python脚本，以下采用2种方法获取cpu负载。
1、读取cpu负载文件：
#!/usr/bin/env python #-*- coding:utf-8 -*- '''cpu负载检测 for nagios''' import sys def check_load(): loadf=open('/proc/loadavg','r') allavg=loadf.readline() load5avg=float(allavg.split()[0]) load10avg=float(allavg.split()[1]) load15avg=float(allavg.split()[2]) loadf.close() print load5avg n=0 cpunf=open('/proc/cpuinfo','r') for i in cpunf.readlines(): if i.split(':')[0].strip() == 'processor': n+=1 cpunf.close() if load5avg > n: print "critical – load average:%.2f,%.2f,%.2f" %(load5avg,load10avg,load15avg) sys.exit(2) else: print "OK – load average:%.2f,%.2f,%.2f" %(load5avg,load10avg,load15avg) sys.exit(0) if __name__ == '__main__': check_load()
2、调用python的os模块获取cpu负载：
#!/usr/bin/env python #-*- coding:utf-8 -*- '''cpu负载检测 for nagios''' import os,sys def check_load(): (d1,d2,d3)=os.getloadavg() print d1 n=0 cpunf=open('/proc/cpuinfo','r') for i in cpunf.readlines(): if i.split(':')[0].strip() == 'processor': n+=1 cpunf.close() if d1 > n: print "critical – load average:%.2f,%.2f,%.2f" %(d1,d2,d3) sys.exit(2) else: print "OK – load average:%.2f,%.2f,%.2f" %(d1,d2,d3) sys.exit(0) if __name__ == '__main__': check_load()
备注：2种方法效果一样，脚本很简单，有好方法的大神，开源出来，互相学习！
