Question

在AWS Cloudwatch中，我想从日志数据中提取值。但是值在消息字段中。无论如何我可以抓住最后一个空格分隔值并记录下来吗？

即。我的日志流：

{"timestamp": 145674445, "message": "Starting new HTTP connection (1): XXXX", "severity": "INFO", "module": "connectionpool", "stack": []}
{"timestamp": 145676445, "message": "Starting new HTTP connection (1): XXXX", "severity": "INFO", "module": "connectionpool", "stack": []}
{"timestamp": 145676445, "message": "deactivated campaign: XXXX05XXXX554aaXXXX9069d4XXXXe7, runtime: 2.63", "severity": "INFO", "module": "credentials", "stack": []}

对于最后一个日志，我想过滤像

这样的模式

{($.message ="deactivated campaign:*, runtime: *")}

我希望能够将度量值I记录为2.63，或最后一个以空格分隔的字符串。

我正在使用GUI，但无法想出办法。可能吗？

非常感谢任何提前帮助！

像这样的东西（没有测试过，但是沿着这些方向的东西）：

    datepicker.addTarget(self, action: "datepickerchanged:", forControlEvents: .ValueChanged)
