• 将salt取到的数据处理


    #!/usr/bin/env python
    #coding:utf-8
    
    
    import json
    
    with open('minfo') as f,open('minfoMiddle','w') as fw:
        for data in f.readlines():
            if '-----' in data or 'mem_total' in data or 'num_cpus' in data:
                continue
            fw.write(data)
            
    with open('minfoMiddle') as f,open('minfoMiddle1','w') as fw:
        for data in f.readlines():
            if data.startswith('minion-'):
                fw.write('
    ')
            data = data.strip('
    ')
            data = data + '	'
            fw.write(data)

    salt取到的数据:salt '*' grains.item num_cpus mem_total localhost > minfo,然后通过上面的代码处理,然后将minfoMiddle1里的内容直接粘贴到excel里即可。

    说明:

    minfo里的数据如下:

    minion-34.16:
        ----------
        localhost:
            nkt-service01-34-16
        mem_total:
            7872
        num_cpus:
            4
    minion-34.12:
        ----------
        localhost:
            recommend-job-34-12
        mem_total:
            7872
        num_cpus:
            4

    minfoMiddle里的数据如下:

    minion-34.16:
        localhost:
            nkt-service01-34-16
            7872
            4
    minion-34.12:
        localhost:
            recommend-job-34-12
            7872
            4
    
    #去掉无用的信息,便于之后的更好处理。

    minfoMiddle1里的数据:

    minion-34.16:        localhost:            nkt-service01-34-16            7872            4    
    minion-34.12:        localhost:            recommend-job-34-12            7872            4    
    minion-34.13:        localhost:            mktadmin-34-13            7872            4    
    
    #这些数据可以直接粘贴到excel里

    以上统计的是不包含磁盘使用的数据,下面将加上磁盘使用。

    salt不能直接取到磁盘信息(后来得知可以通过disk.usage获取单个分区的使用情况),使用salt "*" cmd.run 'df -hl' | egrep -v '/dev/sda2|/dev/sda1|tmpfs' > /tmp/diskinfo得到硬盘信息,然后把硬盘和上面取到的cpu、内存、主机名信息整合,代码如下:

    #!/usr/bin/env python
    #coding:utf-8
    
    list1 = []
    dict_disk = {}
     
    with open('diskinfoMiddle1') as f:
        for data in f.readlines():
            key = data.split(':')[0]
            value = data.split(':')[1]
            dict_disk[key] = value
     
    with open('minfoMiddle') as f:
        for data in f.readlines():
            list1.append(data)
     
    flag = 0
    while flag == 0:
        for i in list1:
            if 'minion-38.132' in i: #最后一个salt节点,循环到这个后就退出while循环
                flag = 1
            if i.startswith('minion-'):
                delmh = i.strip(':
    ')
                index1 = list1.index(i, )
                if dict_disk.get(delmh):
                    list1.insert(index1 + 5, dict_disk[delmh])
                    del dict_disk[delmh]
                else:
                    print('没找到:',delmh)
     
    with open('ccc','w') as f:
        for i in list1:
            f.write(i)
    
            
    with open('ccc') as f,open('ccc1','w') as fw:
        for data in f.readlines():
            if data.startswith('minion-'):
                fw.write('
    ')
            data = data.strip('
    ')
            data = data + '	'
            fw.write(data)
    minfoMiddle的内容同上;
    diskinfoMiddle1的内容如下:
    minion-34.12:    /dev/sda8        47G   11G   33G  25% /home
    minion-34.13:    /dev/sda8        47G  8.2G   36G  19% /home
    minion-34.15:    /dev/sda8        47G  877M   44G   2% /home
    minion-34.16:    /dev/sda8        47G  861M   44G   2% /home
    
    
    #通过salt得到/home的分区情况后,再处理成K-V的形式。

    ccc1文件里的内容可以直接拷贝到excel里。

    以下是网上搜的方法,目前用以下方法统计一台服务器的信息可以,但是统计“*”的总是报异常程序退出,代码如下:

    #!/usr/bin/env python
    #coding:utf-8
    import salt.client as sc
    import json
    ###salt调用
    local = sc.LocalClient()
    ###目标主机指定
    tgt = "minion-25.183"
    ###获取grains,disk信息
    grains = local.cmd(tgt,"grains.items")
    print grains
    diskusage = local.cmd(tgt,"disk.usage")
    cols = "主机名,IP地址,内存(GB),CPU核数,操作系统,数据盘/data(GB)"
    ###打开一个.csv文件,以便写入
    ret_file = open("ret.csv","w")
    ###首先写入开头,有点字段名的意思
    ret_file.write(cols + "
    ")
    try:
        for i in grains.keys():
            ###可能一些主机没有/data数据盘1048576是1024x1024
            if "/home" not in diskusage[i]:
                print "diskusage" + ":" + "have no /data disk"
            else:
                data_vol = int(diskusage[i]["/home"]["1K-blocks"])
                print "diskusage" + ":" , data_vol / 1048576
                ###去掉127.0.0.1这个地址
                ipv4 = str(grains[i]["ipv4"]).replace(", '127.0.0.1'","")
                ###因为一些历史遗留问题,这里取得不是主机名,而是salt-minion的id名,用以判断主要应用
                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_release"]
                if "/home" not in diskusage[i]:
                    disk_data = "None"
                else:
                    disk_data = data_vol / 1048576
                c = ","
                ###连接并写入
                line = hostname + c + ipv4 + c + str(mem) + c + str(num_cpu) + c + str(OS) + c + str(disk_data)
                ret_file.write(line + "
    ")
    except Exception:
        print "Exception:
    "
    finally:
        ret_file.close()
