Profiler
The profiler provides a way to determine how long code takes to execute without having to duplicate Stopwatch code in multiple places and with a mechanism to conditionally disable the stopwatch and completion action(s).
A ProfilerManager can be registed as a dependency in Startup.cs using the following method:
services.AddProfiler();
If you want to override the default options you can do so:
services.AddProfiler(options => {
options.IsEnabled = hostEnv.IsDevelopment();
});
You can also customize the completion action:
services.AddProfiler(options => {
options.Completion = (name, duration, manager) => manager.Logger.LogTrace($"{name} took {duration.TotalMilliseconds}ms");
});
When you resolve a dependency for ProfilerManager, you can use the Instantiate() method to profile some code execution within a using block (to call the Dispose() method of the ProfileInstance):
public class SomeClass
{
private ProfilerManager Manager { get; }
public SomeClass(ProfilerManager manager)
{
Manager = manager;
}
public void SomeMethod()
{
using(var profiler = Manager.Instantiate("Profiler for Thread.Sleep(1000)"))
{
Thread.Sleep(1000);
}
}
}
