先建一个空的项目和之前的nancyfx系列一样的步骤

然后建三个文件夹models，module，views

然后分别安装一下组件

jquery

microsoft.aspnet.signalr

microsoft.owin

nancy

nancy.owin

然后往model类里面添加cpuhub类，broadcaster类

cpuhub类

NancyFx框架检测任务管理器详解

public class cpuhub:hub
  {
    private readonly broadcaster broadcaster;
    public cpuhub():this(broadcaster.broadcaster)
    {

    }
    public cpuhub(broadcaster broadcaster)
    {
      this.broadcaster = broadcaster;
    }
  }

broadcaster类

public class broadcaster
  {
    private readonly static lazy<broadcaster> lazy = new lazy<broadcaster>(()=>new broadcaster(globalhost.connectionmanager.gethubcontext<cpuhub>().clients));

    private readonly timespan timespan = timespan.frommilliseconds(1000);
    private readonly timer timer;
    public static broadcaster broadcaster
    {
      get { return lazy.value; }
    }
    private ihubconnectioncontext hubconnectioncontext
    {
      get;
      set;
    }
    private broadcaster(ihubconnectioncontext hubconnectioncontexts)
    {
      hubconnectioncontext = hubconnectioncontexts;
      timer = new timer(broadcastcpuusage,null,timespan,timespan);
    }
    private void broadcastcpuusage(object o)
    {
      string cpu = getcurrentcpu();

    }
    private string getcurrentcpu()
    {
      string currentcpu = "";
      httpclient httpclient = new httpclient();
      httpclient.baseaddress = new uri("http://localhost:3039");
      var response = httpclient.getasync("api/cpu").result;
      if (response.issuccessstatuscode)
      {
        currentcpu = response.content.readasstringasync().result;
      }
      return currentcpu;
    }
  }

然后在往module里面添加cpumodule类

public class cpumodule:nancymodule
  {
    performancecounter performancecounter;
    public cpumodule():base("api/cpu")
    {
      initializeperformancecounter();
      get("/",lexan=> 
      {
        int cpu = (int)math.ceiling(performancecounter.nextvalue());
        return response.astext(cpu.tostring());
      });
    }
    private void initializeperformancecounter()
    {
      performancecounter = new performancecounter();
      performancecounter.categoryname = "";
      performancecounter.countername = "";
      performancecounter.instancename = "";
      performancecounter.nextvalue();
      thread.sleep(1000);
    }
  }

然后添加index.html页面在根目录下

<!doctype html>
<html>
<head>
  <title>nancytaskmanager</title>
</head>
<body>
  <label id="lblval"></label>
  <br />
  <canvas id="cvpercentage"></canvas>
  <br />
  <br />
  <canvas id="cvgraph" height="450" width="600"></canvas>
  <script src="scripts/jquery-2.1.0.js"></script>
  <script src="scripts/jquery.signalr-2.0.2.js"></script>
  <script src="scripts/chart.js"></script>
  <script src="/signalr/hubs"></script>
  <script src="scripts/taskmanager.js"></script>
</body>
</html>

继续往根目录里面添加startup类

[assembly:owinstartup(typeof( nancyfxtaskmanager.startup))]
namespace nancyfxtaskmanager
{
  public class startup
  {
    public void configuration(iappbuilder app)
    {
      app.mapsignalr().usenancy();
      
    }
  }
}
