So far, we have seen how we can use the different profiling tools to profile the performance of the application when needed so as to assist us in figuring out which portion of the code is causing performance bottlenecks. But how will we know whether an operation is taking long than it should?

One of the answers to this could be the slow response times being reported by users, but that could have quite a lot of factors behind it, which may involve a slowdown at the user end only.

There are a few other mechanisms that we can use to monitor the performance issues in our application in real time. So, let's take a look at one of these methods, which allows us to gather information about the time taken for individual requests.
