linux-node1.oldboyedu.com 192.168.1.31 安裝salt-minion

這裏主要用到saltstack的grains,就是saltstack minion端生成的一些靜態信息，比如CPU，內存，主機名什麽的，而這些就是我們所需要的

執行salt \* grains.items,會打印一大堆的默認抓取的信息，其中一部分，如下

我們當然只挑我們需要的，操作如下

獲取主機名

salt linux-node1.oldboyedu.com grains.item host

獲取IP地址

salt linux-node1.oldboyedu.com grains.item ipv4

獲取CPU核數

salt \* grains.item num_cpus

以此類推，根據自己所需，提取~~~

值得註意的是，grains信息裏面並沒有硬盤信息，所以還需通過disk.usage這個選項，得到我們所需的硬盤信息

執行salt linux-node1.oldboyedu.com disk.usage

其中1K-blocks即我們所需的硬盤信息，根據需求只需要盤/,所以後面就會計算這個盤的配額

11.py

#coding=utf-8

import salt.client as sc

import json

###salt調用

local = sc.LocalClient()

###目標主機指定

tgt = "*"

###獲取grains，disk信息

grains = local.cmd(tgt,"grains.items")

diskusage = local.cmd(tgt,"disk.usage")

###主要應用列表即文件開頭

app_name = ["tomcat","zookeeper","redis","mysql","nginx"]

cols = "Hostname,IP address,RAM(GB),CPU num,Operation,DATA /(GB),project"

###打開一個.csv文件，以便寫入

ret_file = open("ret.csv","w")

###首先寫入開頭，有點字段名的意思

ret_file.write(cols + "\n")

try:

for i in grains.keys():

###打印信息可註釋掉

print grains[i]["nodename"]

print "ipv4" + ":" ,grains[i]["ipv4"]

print "mem_total" + ":" , grains[i]["mem_total"] / 1024 + 1

print "num_cpus" + ":" , grains[i]["num_cpus"]

print "osfullname" + ":" , grains[i]["osfullname"]

print "release" + ":" , grains[i]["lsb_distrib_id"]

###萬一主機沒有/ 數據盤1048576是1024x102

if "/" not in diskusage[i]:

print "diskusage" + ":" + "have no /data disk"

else:

data_vol = int(diskusage[i]["/"]["1K-blocks"])

print "diskusage" + ":" , data_vol / 1048576

###去掉127.0.0.1這個地址

ipv4 = str(grains[i]["ipv4"]).replace(", '127.0.0.1'","")

###因為一些歷史遺留問題，這裏取得不是主機名，而是salt-minion的id名，用以判斷主要應用

hostname = grains[i]["id"]

ipv4 = str(grains[i]["ipv4"]).replace(", '127.0.0.1'","")

ipv4 = ipv4.replace(",","and")

mem = grains[i]["mem_total"] / 1024 + 1

num_cpu = grains[i]["num_cpus"]

OS = grains[i]["osfullname"] + grains[i]["lsb_distrib_id"]

if "/" not in diskusage[i]:

disk_data = "None"

else:

disk_data = data_vol / 1048576

###通過minion ID名來判斷主要運行服務，比如xx-mysql-1，則運行mysql

for j in app_name:

if j in hostname.lower():

app = j

break

else:

app = "undefined"

c = ","

###連接並寫入

line = hostname + c + ipv4 + c + str(mem) + c + str(num_cpu) + c + str(OS) + c + str(disk_data) + c + app

ret_file.write(line + "\n")

except Exception,e:

print "Exception:\n",e

finally:

ret_file.close()

執行salt \* grains.items,發現"lsb_distrib_id"代替了原來的"lsb_distrib_release"，所以上面用了"lsb_distrib_id"

[root@linux-node0 ~]# python 11.py

linux-node0

ipv4: ['127.0.0.1', '192.168.1.30', '192.168.1.38']

mem_total: 1

num_cpus: 1

osfullname: CentOS Linux

release: CentOS Linux

diskusage: 16

linux-node1

ipv4: ['127.0.0.1', '192.168.1.31', '192.168.122.1']

mem_total: 3

num_cpus: 1

osfullname: CentOS Linux

release: CentOS Linux

diskusage: 16

執行後在同一目錄下生成ret.csv文件，打開如下：
