有没有办法查看Azure Functions运行时的更新时间?

问题描述

我们开始看到我们的功能之一与DryIoc访问已处置的Singleton对象有关的一些新错误.有几篇文章建议将 FUNCTIONS_WORKER_RUNTIME 设置为特定版本.我可以在Azure门户中看到当前已设置我们的运行时

这只能满足您查看更新时间的需求，而不能通知您.天蓝色功能的通知系统没有此事件.

原始答案:

FUNCTIONS_WORKER_RUNTIME 用于指定函数使用的语言.我认为您在说的是 FUNCTIONS_EXTENSION_VERSION .

此文档讨论了功能应用程序运行时版本更新的更新:

https://docs.microsoft.com/zh-cn/azure/azure-functions/set-runtime-version#automatic-and-manual-version-updates

这是一项内置功能，它不会通知您.如果仅提供主要的运行时版本，则当次要版本可以更新且没有重大更改时，它将自动更新.如果要避免这种情况，可以将 FUNCTIONS_EXTENSION_VERSION 设置为次要版本，而不是像〜2 这样的主要版本.如果这样做，它将不会自动更新.

We started seeing some new errors in one of our functions in relation to a DryIoc accessing a disposed Singleton object. There are several posts suggesting to set the FUNCTIONS_WORKER_RUNTIME to a specific version. I can see in the Azure Portal that our runtime is currently set 2.0.13759.0 which was released on June 1, 2020. There have been a few more releases since that time, which leads me to my question. I'm not necessarily saying it is the cause of our issue, but how can I tell when a consumption plan's runtime was updated?

解决方案

Update Answer:

If you just want to know when the runtime update instead of notify you know when update, it is possiable.

Please follow these steps:

1, Use this url in your browser to go to the kudu of your function app:

https://yourfunctionappname.scm.azurewebsites.net/DebugConsole

2, Click Debug Console -> CMD, and then Go to LogFiles/eventlog.xml, it will store the update time of the runtime. The structure is like below:

This can only meet your needs of seeing the update time, but can not notify you. The notify system of azure function dont have this event.

Original Answer:

FUNCTIONS_WORKER_RUNTIME is used to specify the language your function is using. I think what you are talking about is FUNCTIONS_EXTENSION_VERSION.

This doc talks about the update of the function app runtime version update:

https://docs.microsoft.com/en-us/azure/azure-functions/set-runtime-version#automatic-and-manual-version-updates

This a built-in feature, it will not notify you. If you only give the major runtime version, it will update automatically when a minor version is available to update and no breaking changes. If you want to avoid this, you can set the FUNCTIONS_EXTENSION_VERSION as the minor version instead of major version like ~2. If you do that, it will not update automatically.
