将值标记为警告或关键

我有一个字典如下(dict命名为channel_info):

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

我试图遍历字典并报告值警告或严重。我必须参与该计划

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

然而情况并非如此,我将所有值都置于关键状态。

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

如果最后一个if条件(if args.warning and args.critical)放置,那么为了确保程序能够使用1(-w-c)或两个参数运行。任何有关我做错的帮助将不胜感激

我想你忘了分支#3上的 float (每个[1])。即将字符串与浮点数进行比较。

更有理由将比较值格式化一次,而不是每次都进行浮点运算(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

解决了它。原来有两个问题

  1. JL Peyret被发现时,我错过了漂浮物。
  2. 然而-c不能单独工作的主要问题是这两个参数都有默认值,当我只使用-c时,第一个if语句正在执行(因为有一个值)并且它相当于真)并且所有值都被标记为警告
