There are more than one CurrentProcessMonitor created by hosting

[kunga]

And some of them are not properly set up:

var monitor = environment.HostExtensions.Get<CurrentProcessMonitor>();

var metrics = monitor.ObserveMetrics(10.Seconds()).First();

environment.Log.Info("Metrics: {Metrics}", metrics);

prints MemoryLimit without

.SetMemoryBytesProvider(() => context.Setup.Limits.MemoryBytes);

setting.
