有没有办法以编程方式检查 AppFabric 缓存主机是否处于活动状态？

Question

我想通过c#编程获取AppFabric缓存主机的运行状态。有没有办法做到这一点？

Answer 1

您可以按照以下步骤使用Powershell 命令进行操作；

• 下载PowerShell v2 SDK
• 为运行我们的 Powershell 命令创建环境。

var initialSessionState = InitialSessionState.CreateDefault();
initialSessionState.ThrowOnRunspaceOpenError = true;
runspace = RunspaceFactory.CreateRunspace(initialSessionState);
runspace.Open();

• 让我们创建一个管道。

var pipeline = runspace.CreatePipeline();

• 将命令行传递到在缓存中运行的 Powershell 中的管道。

pipeline.Commands.Add(new Command("Use-CacheCluster"));
pipeline.Commands.Add(new Command("Get-CacheHost"));

Get-CacheHost 为我们提供缓存服务器信息。并使用Invoke() 方法运行。

var result = pipeline.Invoke();

• 带有result对象，

var initialSessionState = InitialSessionState.CreateDefault();
initialSessionState.ImportPSModule(new[] { "DistributedCacheAdministration" });
initialSessionState.ThrowOnRunspaceOpenError = true;

runspace = RunspaceFactory.CreateRunspace(initialSessionState);

runspace.Open();

var pipeline = runspace.CreatePipeline();
pipeline.Commands.Add(new Command("Use-CacheCluster"));
pipeline.Commands.Add(new Command("Get-CacheHost"));
var result = pipeline.Invoke();

var hostInfo = (HostInfo)result[0].BaseObject;

Console.Out.WriteLine("Server Name        : " + hostInfo.HostName);
Console.Out.WriteLine("Server Port      : " + hostInfo.PortNo);
Console.Out.WriteLine("Server Service Name : " + hostInfo.ServiceName);
Console.Out.WriteLine("Server Status    : " + hostInfo.Status);
Console.Out.WriteLine("Server Version     : " + hostInfo.VersionInfo);

另外，不要忘记添加这些程序集引用；

• Microsoft.ApplicationServer.Caching.Client
• Microsoft.ApplicationServer.Caching.Core
• Microsoft.ApplicationServer.Caching.Management
• System.Management.Automation
