Properties

ActivationSchedulingQuantum

ActivationSchedulingQuantum is a soft time limit on the duration of activation macro-turn (a number of micro-turns). If a activation was running its micro-turns longer than this, we will give up the thread. If this is set to zero or a negative number, then the full work queue is drained (MaxWorkItemsPerTurn allowing).

Declaration

public TimeSpan ActivationSchedulingQuantum { get; set; }

Property Value

Type	Description
TimeSpan

AdditionalAssemblyDirectories

public Dictionary<string, SearchOption> AdditionalAssemblyDirectories { get; set; }

Property Value

Type	Description
Dictionary<System.String, SearchOption>

DefaultConnectionLimit

Declaration

public int DefaultConnectionLimit { get; set; }

Property Value

Type	Description

DelayWarningThreshold

The DelayWarningThreshold attribute specifies the work item queuing delay threshold, at which a warning log message is written. That is, if the delay between enqueuing the work item and executing the work item is greater than DelayWarningThreshold, a warning log is written. The default value is 10 seconds.

Declaration

public TimeSpan DelayWarningThreshold { get; set; }

Property Value

Type	Description
TimeSpan

DNSHostName

The DNS host name of this silo. This is a true host name, no IP address. It is NOT settable, equals Dns.GetHostName().

Declaration

public string DNSHostName { get; }

Property Value

Type	Description
System.String

The IPEndPoint this silo uses for silo-to-silo communication.

Declaration

public IPEndPoint Endpoint { get; }

Property Value

Type	Description
IPEndPoint

public bool Expect100Continue { get; set; }

Property Value

Type	Description
System.Boolean

Generation

The epoch generation number for this silo.

Declaration

public int Generation { get; set; }

Property Value

Type	Description
System.Int32

HostNameOrIPAddress

The host name or IP address of this silo. This is a configurable IP address or Hostname.

Declaration

public string HostNameOrIPAddress { get; set; }

Property Value

Type	Description
System.String

IsGatewayNode

Whether this is silo is a proxying gateway silo.

Declaration

public bool IsGatewayNode { get; }

Property Value

Type	Description
System.Boolean

IsPrimaryNode

Whether this is a primary silo (applies for dev settings only).

Declaration

public bool IsPrimaryNode { get; set; }

Property Value

Type	Description
System.Boolean

IsSeedNode

Whether this is one of the seed silos (applies for dev settings only).

Declaration

public bool IsSeedNode { get; set; }

Property Value

Type	Description
System.Boolean

LimitManager

The values for various silo limits.

Declaration

public LimitManager LimitManager { get; }

Property Value

Type	Description
LimitManager

LoadSheddingEnabled

The LoadShedding element specifies the gateway load shedding configuration for the node. If it does not appear, gateway load shedding is disabled.

Declaration

public bool LoadSheddingEnabled { get; set; }

Property Value

Type	Description
System.Boolean

LoadSheddingLimit

The LoadLimit attribute specifies the system load, in CPU%, at which load begins to be shed. Note that this value is in %, so valid values range from 1 to 100, and a reasonable value is typically between 80 and 95. This value is ignored if load shedding is disabled, which is the default. If load shedding is enabled and this attribute does not appear, then the default limit is 95%.

Declaration

public int LoadSheddingLimit { get; set; }

Property Value

Type	Description
System.Int32

MaxActiveThreads

The MaxActiveThreads attribute specifies the maximum number of simultaneous active threads the scheduler will allow. Generally this number should be roughly equal to the number of cores on the node. Using a value of 0 will look at System.Environment.ProcessorCount to decide the number instead, which is only valid when set from xml config

Declaration

public int MaxActiveThreads { get; set; }

Property Value

Type	Description
System.Int32

MinDotNetThreadPoolSize

Declaration

public int MinDotNetThreadPoolSize { get; set; }

Property Value

Type	Description
System.Int32

Port
