python – 将值标记为警告或关键

发布时间：2020-12-20 13:51:56 所属栏目：Python 来源：网络整理

导读：我有一个字典如下(dict被命名为channel_info)： {'flume02': u'98.94420000000001','flume03': u'32.562999999999995','flume01': u'2.15'} 我试图循环通过字典并报告值警告或关键.我不得不参与该计划 parser.add_argument('-w','--warning',type=int,help='

我有一个字典如下(dict被命名为channel_info)：

{'flume02': u'98.94420000000001','flume03': u'32.562999999999995','flume01': u'2.15'}

我试图循环通过字典并报告值警告或关键.我不得不参与该计划

parser.add_argument('-w','--warning',type=int,help='Warning threshold',default=85)
parser.add_argument('-c','--critical',help='Critical threshold',default=95)

所以基本上当我运行像myprog.py -w 80 -c 90这样的程序时,我想要
flume02是关键的(在这种情况下,这将是唯一的输出).如果任何其他密钥的值大于80或90,则它们将分别报告为警告或关键.

然而事实并非如此,我认为所有的价值都是关键的.

相关代码：

if args.warning and not args.critical:
        for each in channel_info.items():
            if float(each[1]) > float(args.warning):
                print 'WARNING | {} is {} percent full'.format(*each)
        exit(1)

    if args.critical and not args.warning:
        for each in channel_info.items():
            if float(each[1]) > float(args.critical):
                print 'CRITICAL | {} is {} percent full'.format(*each)
        exit(2)

    if args.warning and args.critical:
        for each in channel_info.items():
            if float(args.warning) < each[1] < float(args.critical):
                print 'WARNING | {} is {} percent full'.format(*each)
            elif each[1] > float(args.critical):
                print 'CRITICAL | {} is {} percent full'.format(*each)

输出：

CRITICAL | flume02 is 99.9892 percent full
CRITICAL | flume03 is 51.4497 percent full
CRITICAL | flume01 is 7.95 percent full

我把if if条件(如果是args.warning和args.critical)放在一起,以确保程序能够以1(-w或-c)或两个参数运行.任何有关我做错的任何帮助将不胜感激

解决方法

我想你忘记了#3分支上的浮动(每个[1]).即比较字符串到浮点数.

更有理由将比较值格式化一次,而不是每次都执行浮点数(xyz).

threshold_crit = 90.0
threshold_warn = 80.0

for each in channel_info.items():
    # value = float(each[1])
    value = each[1]

    if threshold_crit < value < threshold_warn:
        print 'WARNING | {} is {} percent full'.format(*each)
    elif value > threshold_crit:
        print 'CRITICAL | {} is {} percent full'.format(*each)

输出：

CRITICAL | flume02 is 98.94420000000001 percent full
 CRITICAL | flume03 is 32.562999999999995 percent full
 CRITICAL | flume01 is 2.15 percent full

将代码更改为：

value = float(each[1])
    #value = each[1]

输出：

CRITICAL | flume02 is 98.94420000000001 percent full
