如何找到Service Fabric應用程序服務與節點的關聯？

Question

使用System.Fabric.FabricClient.QueryClient方法從遠程服務結構群集中提取信息，如何將應用程序服務與托管這些服務的節點相關聯？

我已經利用ListEndPoints答案中的答案來獲取有關我的服務和分區的更多詳細信息，但是我看不到將服務映射到節點所需的屬性。

var fabricClient = new FabricClient(credentials, connectionString);
var nodes = fabricClient.QueryManager.GetNodeListAsync().Result;
var apps = fabricClient.QueryManager.GetApplicationListAsync().Result;
var services = fabricClient.QueryManager.GetServiceListAsync(app.ApplicationName).Result;
var partitions = fabricClient.QueryManager.GetPartitionListAsync(service.ServiceName).Result;

例如

• APPA
  • ServiceA_A
    • NodeFe0
    • NodeFe1
  • ServiceA_B
    • NodeBe0
    • NodeBe1
    • NodeBe2
• APPB
  • ServiceB_A
    • NodeFe0
    • NodeFe1

此代碼有助於您大致了解哪個節點上正在運行哪個服務分區

var fabricClient = new FabricClient();
var nodes = await fabricClient.QueryManager.GetNodeListAsync("");
var apps = fabricClient.QueryManager.GetApplicationListAsync().Result;
foreach (var app in apps)
{
    Console.WriteLine($"Discovered application:'{app.ApplicationName}");
    var deployedPartitions = new Dictionary<Guid, List<string>>();
    foreach (var node in nodes)
    {
        //get deployed partitions per node
        var deployed = await fabricClient.QueryManager.GetDeployedReplicaListAsync(node.NodeName, app.ApplicationName);

        foreach (var dep in deployed)
        {
             List<string> list;
             if (!deployedPartitions.TryGetValue(dep.Partitionid, out list))
             {
                  list = new List<string>();
                  deployedPartitions.Add(dep.Partitionid, list);
             }
             list.Add(node.NodeName);
         }
     }

     var services = await fabricClient.QueryManager.GetServiceListAsync(app.ApplicationName);
     foreach (var service in services)
     {
         Console.WriteLine($"Discovered Service:'{service.ServiceName}");
         var partitions = await fabricClient.QueryManager.GetPartitionListAsync(service.ServiceName);
         foreach (var partition in partitions)
         {
              var partitionId = partition.PartitionInformation.Id;
              if (deployedPartitions.TryGetValue(partitionId, out var nodeNames))
              {
                  Console.WriteLine($"Discovered {service.ServiceKind} Service:'{service.ServiceName} PartitionId: '{partitionId}' running on nodes {string.Join(", ", nodeNames)}");
              }
         }
    }
 }
