Determine memory used by asp.net cache in shared hosting

Question

According to this question, I want to know if asp.net's system.web.caching.cache is good for me, or I should use database caching?

So, I need to know how much memory is being used by system.Web.caching.cache? But since I am using a shared hosting server, I can't use task manager. Is there any way to determine how much memory is used by system.web.caching.cache using some code?

One fast way to see how many working memory your application use is to direct ask the garbage collection.

long bytes = GC.GetTotalMemory(false);
txtMemoryUsed.Text = bytes.ToString();

and use this literal <asp:Literal runat="server" ID="txtMemorysUsed" EnableViewState="false" />

But you can get more details using the PerformanceCounter, for example you can get how many virtual memory the pools used by this code:

 var oPerfCounter = new PerformanceCounter();
oPerfCounter.CategoryName = "Process";
oPerfCounter.CounterName = "Virtual Bytes";
oPerfCounter.InstanceName = "aspnet_wp";
txtMemorysUsed.Text = "Virtual Bytes: " + oPerfCounter.RawValue + " bytes";

You can use all this parameters to get information's for your pool.

Processor(_Total)\% Processor Time
Process(aspnet_wp)\% Processor Time
Process(aspnet_wp)\Private Bytes
Process(aspnet_wp)\Virtual Bytes
Process(aspnet_wp)\Handle Count
Microsoft® .NET CLR Exceptions\# Exceps thrown / sec
ASP.NET\Application Restarts
ASP.NET\Requests Rejected
ASP.NET\Worker Process Restarts (not applicable to IIS 6.0)
Memory\Available Mbytes
Web Service\Current Connections
Web Service\ISAPI Extension Requests/sec

for example, this parametres get the cpu load.

oPerfCounter.CategoryName = "Processor";
oPerfCounter.CounterName = "% Processor Time";
oPerfCounter.InstanceName = "_Total";
txtOutPut.Text = "Current CPU Usage: " + oPerfCounter.NextValue() + "%";

I have test that on local iis and works.

Does GC gives me the memory used by just current Web application?

Aristos Over a year ago

@Mahdi in a shared environment the pool is run many sites, your site is lives with other sites, except if you have ask for a "private" pool. (so its not just current web application, but is the pool). So you get the memory of your pool (including other sites that runs together)

My control panel is plesk, and it seems that every user has an application pool. (I can stop/start it or even limit CPU usage of my sites). So, is my application pool private?

Aristos Over a year ago

@Mahdi tells you only your application.

@Mahdi if you have this options, probably you have distinct pool to not affect others.
