    <p>I'm trying to access the performance counters located in <a href="http://msdn.microsoft.com/en-us/library/x2tyfybc(v=VS.100).aspx" rel="noreferrer">".NET CLR Memory category"</a> through C# using the PerformanceCounter class. However a cannot instantiate the categories with what I would expect was the correct category/counter name</p> <pre><code>new PerformanceCounter(".NET CLR Memory", "# bytes in all heaps", Process.GetCurrentProcess().ProcessName); </code></pre> <p>I tried looping through categories and counters using the following code</p> <pre><code>string[] categories = PerformanceCounterCategory.GetCategories().Select(c =&gt; c.CategoryName).OrderBy(s =&gt; s).ToArray(); string toInspect = string.Join(",\r\n", categories); System.Text.StringBuilder interestingToInspect = new System.Text.StringBuilder(); string[] interestingCategories = categories.Where(s =&gt; s.StartsWith(".NET") || s.Contains("Memory")).ToArray(); foreach (string interestingCategory in interestingCategories) { PerformanceCounterCategory cat = new PerformanceCounterCategory(interestingCategory); foreach (PerformanceCounter counter in cat.GetCounters()) { interestingToInspect.AppendLine(interestingCategory + ":" + counter.CounterName); } } toInspect = interestingToInspect.ToString(); </code></pre> <p>But could not find anything that seems to match. Is it not possible to observe these values from within the CLR or am I doing something wrong.</p> <p>The environment, should it matter, is .NET 4.0 running on a 64-bit windows 7 box.</p>

    1. COWas it simply a case of running with admin privilege, as in Oleg's answer? That fixed it for me.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
