使用python进行服务器监控
修改：
获取内存的信息：
mem = {}
f = open('/proc/meminfo', 'r')
lines = f.readlines()
f.close()
for line in lines:
if len(line) < 2:
continue
name = line.split(':')[0]
var = line.split(':')[1].split()[0]
mem[name] = float(var)
mem['MemUsed'] = mem['MemTotal'] - mem['MemFree'] - mem['Buffers'] - mem['Cached']
res = {}
res['percent'] = int(round(mem['MemUsed'] / mem['MemTotal'] * 100))
res['used'] = round(mem['MemUsed'] / (1024 * 1024), 2)
res['MemTotal'] = round(mem['MemTotal'] / (1024 * 1024), 2)
res['Buffers'] = round(mem['Buffers'] / (1024 * 1024), 2)
# return res
print res
print "res['percent']",res['percent']# print "res['percent']",res['percent']
# memory_stat(res)执行结果：
