How to get the available RAM and the CPU usage?

These methods are very usefull in order to monitor the system and particulary the amount of the available RAM in MB (MegaBytes) and the cpu usage in percents.

protected PerformanceCounter cpuCounter;
protected PerformanceCounter ramCounter;

cpuCounter = new PerformanceCounter();

cpuCounter.CategoryName = “Processor”;
cpuCounter.CounterName = “% Processor Time”;
cpuCounter.InstanceName = “_Total”;

ramCounter = new PerformanceCounter(“Memory”, “Available MBytes”);

/*
Call this method every time you need to know
the current cpu usage.
*/

public string getCurrentCpuUsage(){
            cpuCounter.NextValue()+”%”;
}

/*
Call this method every time you need to get
the amount of the available RAM in Mb
*/
public string getAvailableRAM(){
            ramCounter.NextValue()+”Mb”;
}
