前几天看到朋友郑彦生分享的psutil模块的使用方法,感觉对于监控又多了一层想法,因为前期主要是通过saltstack,收集数据,但是有时候比较麻烦,在小型规模做监控的时候还是建议用psutil模块,方便快捷:首先介绍psutil模块的一些基本用法:
1、监控cpu:
>>>importpsutil >>>psutil.cpu_count()#查看线程 >>>psutil.cpu_percent()#查看cpu负载 |
2、查看内存相关信息:
内存可以查看总共多少内存,使用了多少,还剩多少:
>>> mem = psutil.virtual_memory()
#统计所有的信息
svmem(total=67502866432L,available=61983199232L,percent=8.1999999999999993,used=7092293632L,free=60410572800L,active=5551243264,inactive=410374144,buffers=335728640L,cached=1236897792) >>>mem.total#内存总数 >>>mem.used#使用了多少内存 >>>mem.free#剩余内存 |
3、硬盘的IO和使用情况:
>>>psutil.disk_partitions() [sdiskpart(device='/dev/mapper/VolGroup-lv_root',mountpoint='/',fstype='ext4',opts='rw'),sdiskpart(device='/dev/sda3',mountpoint='/boot',fstype='ext4',opts='rw'),sdiskpart(device='/dev/mapper/VolGroup-lv_home',mountpoint='/home',fstype='ext4',opts='rw')] >>>psutil.disk_partitions('/') [sdiskpart(device='/dev/mapper/VolGroup-lv_root',mountpoint='/',fstype='ext4',opts='rw'),sdiskpart(device='proc',mountpoint='/proc',fstype='proc',opts='rw'),sdiskpart(device='sysfs',mountpoint='/sys',fstype='sysfs',opts='rw'),sdiskpart(device='devpts',mountpoint='/dev/pts',fstype='devpts',opts='rw,gid=5,mode=620'),sdiskpart(device='tmpfs',mountpoint='/dev/shm',fstype='tmpfs',opts='rw'),sdiskpart(device='/dev/sda3',mountpoint='/boot',fstype='ext4',opts='rw'),sdiskpart(device='/dev/mapper/VolGroup-lv_home',mountpoint='/home',fstype='ext4',opts='rw'),sdiskpart(device='',mountpoint='/proc/sys/fs/binfmt_misc',fstype='binfmt_misc',opts='rw')] >>>psutil.disk_io_counters() sdiskio(read_count=107158,write_count=20666736,read_bytes=1792485376,write_bytes=133169932288,read_time=130421,write_time=337076882) >>>psutil.net_io_counters() snetio(bytes_sent=984192973,bytes_recv=1274031495,packets_sent=3924134,packets_recv=6024010,errin=0,errout=0,dropin=0,dropout=0) |
