Using the System.Fabric.FabricClient.QueryClient
methods to pull information from a remote service fabric cluster, how can I associate the application services with the nodes hosting those services?
I've leveraged the answer at the ListEndPoints answer to get more details about my services and partitions but I do not see the properties I need for mapping services to nodes.
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;
eg
This code helps you get an overview of which service partition is running on which nodes
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)}");
}
}
}
