aws-lambda - CloudWatch Insights：获取错误 lambda 的日志

Question

一个 lambda 可以有一个成功或错误的结果。

我想查看错误的 lambda 日志。我正在尝试通过 CloudWatch Insights 查询来做到这一点。

我怎样才能做到这一点？

Answer 1

如果有人来这里寻找解决方案，这就是我使用的：

filter @message like /(?i)(Exception|error|fail)/| fields @timestamp, @message | sort @timestamp desc | limit 20

Answer 2

我使用以下查询来获取答案中提到的查询未涵盖的那些错误，并且我只能在监控仪表板中看到失败。

fields @timestamp, @message
| sort @timestamp desc
| filter @message not like 'INFO' 
| filter @message not like 'REPORT'
| filter @message not like 'END'
| filter @message not like 'START'
| limit 20

这是此查询涵盖的一些示例

Answer 3

您可以在 CloudWatch Logs Insights 中运行以下查询。

filter @type = "REPORT"
    | stats max(@memorySize / 1000 / 1000) as provisonedMemoryMB,
        min(@maxMemoryUsed / 1000 / 1000) as smallestMemoryRequestMB,
        avg(@maxMemoryUsed / 1000 / 1000) as avgMemoryUsedMB,
        max(@maxMemoryUsed / 1000 / 1000) as maxMemoryUsedMB,
        provisonedMemoryMB - maxMemoryUsedMB as overProvisionedMB
    

Answer 4

如果有人在寻找如何搜索错误或登录AWS Log insights，可以使用此查询进行搜索：

fields @timestamp, @message
| filter @message like /text to search/
| sort @timestamp desc
| limit 20

实际上，只需在查询编辑器中选择log group(s)并添加一个新行| filter @message like /text to search/就足够了。其余的都是默认的。

另外，请记住配置搜索历史的时间跨度，以防找不到相关结果。默认情况下，它只搜索最后一个1h.

在您的控制台中，导航到您的 lambda 配置页面。在左上角，单击Monitoring，然后View logs in CloudWatch在右侧。
