Mono Performance Counters
Mono performance counters
This page lists the performance counters currently implemented in the Mono runtime.
Note: despite being implemented and present in the runtime, not all counters are being updated as of the time of this writing (April 16 2010).
The list is based on the trunk version of the runtime, so not all of them might be present in your version of Mono.
Each category is listed in a section of its own, to facilitate navigation.

Accessing performance counters
The code snippet below shows you how to read a counter from the current process. Note that the Mono Memory category name will throw an exception on .NET since that category doesn't exist there - replace it with any other non-Mono specific category+counter name pair and it will work:
using System;
using System.Diagnostics;
class app
{
static void Main (string[] args)
{
string categoryName;
string counterName;
if (args.Length >= 2) {
categoryName = args [0];
counterName = args [1];
} else {
categoryName = "Mono Memory";
counterName = "Total Physical Memory";
}
try {
var pc = new PerformanceCounter (categoryName, counterName);
Console.WriteLine ("Value of performance counter '{0}/{1}': {2}",
categoryName,
counterName,
pc.RawValue);
} catch (InvalidOperationException ex) {
Console.WriteLine ("Category name '{0}' does not exist. {1}", categoryName, ex.Message);
}
}
}
