Мы пытались отследить некоторые проблемы с процессором нашего приложения в экземпляре службы приложения PO C. Мы установили Application Insights, чтобы узнать, сможем ли мы получить более подробную информацию, но это просто приводит к тому, что наше приложение работает ужасно.
Когда он запущен, наш журнал событий приложений показывает следующую ошибку и трассировку стека, которая, как я предполагаю, связана с тем, почему производительность настолько низкая, когда работает эта служба.
Любые мысли на что мы можем обратить внимание, чтобы это работало гладко?
