我有一个简单的 Azure 函数，当在 Blob 存储中添加新项目时会触发该函数。
该函数读取上传到 Blob 存储的新 JSON 文件并将信息加载到数据库中。
它在本地工作，当我部署该功能时，它也按预期工作，但是当我几天后检查数据时，我发现该功能没有被触发。但是，函数应用显示状态“正在运行”。我重新启动了应用程序，它再次开始上传数据，只是在几个小时后停止了。
它似乎只有在我重新启动应用程序或在浏览器中打开 Azure Functions 时才有效。
一些额外的数据：
我正在添加一些我认为可能相关的信息，但我是 Azure Functions 的新手，所以如果有任何更重要的信息我忽略了，请随时询问。我也有 Application Insights 监控应用程序。
运行时版本：3.0.15571.0
模式：消费
1. Application Insights 检查
我检查了过去 3 天的请求。它的工作时间与我昨天试图找出问题所在的时间相同。有很多请求，因为它正在赶上所有未处理的旧文件：
最后一个请求是昨天，因为我们可以检查查询：
2.捻度检查
我正在查看的日志是我在函数中编码的预期日志，一些我不知道含义的意外日志，以及我的 SQL 连接上的一些错误：
显示的信息如下：
