Umbraco 7.6.0 - каждое утро сайт перестает отвечать на запросы, а затем снова включается

У нас есть производственная площадка, на которой работает Umbraco 7.6.0. Каждое утро мы получаем оповещение о мониторинге из-за времени отклика на главной странице более 30 секунд, и примерно через 10-15 минут проблема решается сама собой. Прошлой ночью мы изменили уровень детализации журнала на DEBUG, и сегодня утром мы все еще не можем точно определить причину проблемы. Каждый раз, когда возникает эта проблема, мы видим то, что я считаю некоторыми последствиями проблемы — сбой задач Keep Alive и Scheduled Publish (вероятно, время ожидания истекло):

ERROR Umbraco.Web.Scheduling.ScheduledPublishing - Failed (at "https://www.[domainredacted].com:443/umbraco").
System.Threading.Tasks.TaskCanceledException: A task was canceled.
   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)
   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
   at Umbraco.Web.Scheduling.ScheduledPublishing.<PerformRunAsync>d__7.MoveNext()

введите здесь описание изображения

Поскольку использование ЦП и памяти в плане службы приложений Azure во время сбоя было стабильным, это наводит меня на мысль, что существует своего рода взаимоблокировка, и это происходит только один раз в день. К сожалению, журналы DEBUG также бесполезны. Я пытаюсь найти задачу/процедуру, которая начинается, но никогда не заканчивается. Я вижу запланированную публикацию, которая заняла 100 секунд (что довольно долго), но опять же это может быть просто эффект, вызванный проблемой, а не обязательно сама причина. У кого-нибудь есть идеи, в чем может быть проблема и / или как лучше исследовать?

Вот журнал с отредактированной конфиденциальной информацией о проекте:

Просто предположение, но, возможно, IIS перерабатывает веб-сайт, и для повторного запуска требуется некоторое время? Ознакомьтесь с этим вопросом, чтобы узнать об отключении автоматических перезапусков: stackoverflow.com/q/3156925/2963111   -  person harvzor    schedule 30.08.2017

Вы также можете включить монитор запросов в IIS. Это позволяет вам видеть текущие веб-запросы, сделанные к вашему приложению, с количеством времени, в течение которого запрос обрабатывается. Это может быть весьма полезно: stackoverflow.com/q/15621509/2963111   -  person harvzor    schedule 30.08.2017

@Harvey Это довольно стандартная причина, по которой вы это увидите, но в приведенном выше сценарии это не так.   -  person Keith    schedule 31.08.2017

@Harvey Существует ли служба приложений Azure, эквивалентная монитору запросов?   -  person Keith    schedule 31.08.2017

Если он размещен в приложении Azure, скорее всего, это будет запуск приложения или перемещение приложения. Если ваш сайт не оптимизирован достаточно хорошо, иногда вы можете наблюдать довольно медленное время запуска в Azure Apps, я наблюдал более 20 минут на особенно плохо оптимизированных сайтах.

Я думаю, что главный виновник — файловый ввод-вывод во время запуска приложения. Сайт достаточно большой? Также есть ли у него много пользовательских индексов Examine?

Вот несколько полезных советов по повышению производительности в Azure: https://cultiv.nl/blog/making-sure-your-umbraco-site-performs-on-azure/
