具体请参考如下的代码吧。
1、内存信息 / meminfo
返回dict
复制代码 代码示例:
#!/usr/bin/env
python
def memory_stat():
mem = {}
f = open("/proc/meminfo")
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] = long(var) * 1024.0
mem['MemU
sed'] = mem['MemTotal'] - mem['MemFree'] - mem['Buffers'] - mem['Cached']
return mem
2、CPU信息 / cpuinfo
返回list，每核心一dict
复制代码 代码示例:
#!/usr/bin/env python
def cpu_stat():
cpu = []
cpuinfo = {}
f = open("/proc/cpuinfo")
lines = f.readlines()
f.close()
for line in lines:
if line == 'n':
cpu.append(cpuinfo)
cpuinfo = {}
if len(line) < 2: continue
name = line.split(':')[0].rstrip()
var = line.split(':')[1]
cpuinfo[name] = var
return cpu
3、负载信息 / loadavg
返回dict
复制代码 代码示例:
#!/usr/bin/env python
def load_stat():
loadavg = {}
f = open("/proc/loadavg")
con = f.read().split()
f.close()
loadavg['lavg_1']=con[0]
loadavg['lavg_5']=con[1]
loadavg['lavg_15']=con[2]
loadavg['nr']=con[3]
loadavg['last_pid']=con[4]
return loadavg
4、运转时间 / Uptime
返回dict
复制代码 代码示例:
#!/usr/bin/env python
def uptime_stat():
uptime = {}
f = open("/proc/uptime")
con = f.read().split()
f.close()
all_sec = float(con[0])
MINUTE,HOUR,DAY = 60,3600,86400
uptime['day'] = int(all_sec / DAY )
uptime['hour'] = int((all_sec % DAY) / HOUR)
uptime['minute'] = int((all_sec % HOUR) / MINUTE)
uptime['second'] = int(all_sec % MINUTE)
uptime['Free rate'] = float(con[1]) / float(con[0])
return uptime
5、获取网卡流量信息 /proc/net/dev
返回dict,单位byte
复制代码 代码示例:
#!/usr/bin/env python
def net_stat():
net = []
f = open("/proc/net/dev")
lines = f.readlines()
f.close()
for line in lines[2:]:
con = line.split()
"""
intf = {}
intf['interface'] = con[0].lstrip(":")
intf['ReceiveBytes'] = int(con[1])
intf['ReceivePackets'] = int(con[2])
intf['ReceiveErrs'] = int(con[3])
intf['ReceiveDrop'] = int(con[4])
intf['ReceiveFifo'] = int(con[5])
intf['ReceiveFrames'] = int(con[6])
intf['ReceiveCompressed'] = int(con[7])
intf['ReceiveMulticast'] = int(con[8])
intf['TransmitBytes'] = int(con[9])
intf['TransmitPackets'] = int(con[10])
intf['TransmitErrs'] = int(con[11])
intf['TransmitDrop'] = int(con[12])
intf['TransmitFifo'] = int(con[13])
intf['TransmitFrames'] = int(con[14])
intf['TransmitCompressed'] = int(con[15])
intf['TransmitMulticast'] = int(con[16])
"""
intf = dict(
zip(
( 'interface','ReceiveBytes','ReceivePackets',
'ReceiveErrs','ReceiveDrop','ReceiveFifo',
'ReceiveFrames','ReceiveCompressed','ReceiveMulticast',
'TransmitBytes','TransmitPackets','TransmitErrs',
'TransmitDrop', 'TransmitFifo','TransmitFrames',
'TransmitCompressed','TransmitMulticast' ),
( con[0].rstrip(":"),int(con[1]),int(con[2]),
int(con[3]),int(con[4]),int(con[5]),
int(con[6]),int(con[7]),int(con[8]),
int(con[9]),int(con[10]),int(con[11]),
int(con[12]),int(con[13]),int(con[14]),
int(con[15]),int(con[16]), )
)
)
net.append(intf)
return net
6、磁盘空间使用
使用内置python内置函数，返回dict,单位byte。
复制代码 代码示例:
#!/usr/bin/env python
def disk_stat():
import os
hd={}
disk = os.statvfs("/")
hd['available'] = disk.f_bsize * disk.f_bavail
hd['capacity'] = disk.f_bsize * disk.f_blocks
hd['used'] = disk.f_bsize * disk.f_bfree
return hd
