![]() ![]() To enable the profiler just add the -prof flag as followed: node -prof server.js This is mostly useful just for CPU traces.Ĭonfiguration. It records the results of these samples, along with important optimization events such as jit compiles, as a series of ticks. The built-in profiler uses the profiler inside V8 which samples the stack at regular intervals during program execution. Here is a list of tools you can use instead: High CPU node –prof There are some third-party libraries that are not compatible when installating due of the Azure App Service Windows’s platform (ia32), in those scenarios you will need to build the packages based on that platform, review this thread for further reference. For those scenarios you can configure a Node.js profiler for your application. When dealing with High CPU/Memory scenarios in App Service Windows, the best recommendation is to profile your app in your local environment, but sometimes it is hard to reproduce the issue specially not having the same request load or environment. ![]() Written by Johan Zetterberg April 17th 2015.Troubleshooting Node.js High CPU and Memory scenarios in App Service Windows You can capture the "SIGINT" in your NodeJS script and make a clean exit. Windows will send a "SIGINT" to your script to make it stop, then give it a few seconds before it's killed completely. This can be done both from NSSM and the dependency tab in Windows service manager (services.msc). Then Windows will make sure mySQL always starts before your script runs. Lets say your node script access a mySQL server, then add mySQL as a dependency. Make sure you add anything your script depends on as a service dependency. And run even if you are not logged in! Start after another service has started Your Node.JS script will then run as a service and startup after reboot. To start the service, find it in Windows service manager (hit Win+R, type: services.msc and click OK/Enter), or type "net start nameOfYourService" in the command prompt.
