Question

我正在使用一个简单的脚本将数据发送到elasticsearch节点，但在更改我的python版本后，该脚本不再运行。它说错误在第6行，但我不明白为什么。我已尝试在“是”之后添加逗号，但它没有效果。我试过移动我的牙套和括号，它必须起作用。（为了简洁起见，我省略了导入和其他定义的变量）

if "Temporary failure in name resolution" or "Timeout" in output:
            es.index(index='data', doc_type='data', body={
            'macs' : '',
            'data' : line,
            'date' : datetime.now(),
            'down' : 'yes' })

以下是错误：

    snmpwalk: Timeout

Traceback (most recent call last):
  File "script.py", line 6, in <module>
    'down' : 'yes' })

这可能是网络问题，也可能是弹性搜索已用尽的mmapfs目录。

尝试运行以下命令重新启动网络服务器

sudo service network-manager restart

如果它不起作用，请通过运行此命令来更改您的mmap计数

sudo sysctl -w vm.max_map_count=262144

参考 https://www.elastic.co/guide/en/elasticsearch/reference/current/vm-max-map-count.html

python 2.7.6到2.7.12打破了我的脚本
