在Azure上的IISNode中“启用日志记录：true”对性能有什么影响

Question

This article states that it is possible to log the outputs of StdOut and StdErr streams to the file system.

What is the performance impact of doing this? Should I leave it on in production?

Answer 1

As node.js application on Azure Web Apps is handled via iisnode module. And logging enable is only a functionality of iisnode which will have very little impact. As which also should to be a good method to trace error info in production env.

Meanwhile, it is recommended that we can set up staging environments in your Web Apps, separate production and dev staging slot, if we need to use iisnode's troubleshooting configurations as document mentions at Best practices and troubleshooting guide for node applications on Azure Web Apps
