DB Engine Thread Count monitor type for 2014 DBs
RunAs | Microsoft.SQLServer.2014.SQLProbeAccount |
Accessibility | Internal |
Support Monitor Recalculate | False |
ID | Module Type | TypeId | RunAs |
---|---|---|---|
DS | DataSource | Microsoft.SQLServer.2014.DBEngine.ThreadCountMonitor.DataSourceMapped | Default |
CSC | ConditionDetection | System.Performance.ConsecutiveSamplesCondition | Default |
ErrorCondition | ConditionDetection | System.ExpressionFilter | Default |
NormalCondition | ConditionDetection | System.ExpressionFilter | Default |
ID | ParameterType | Selector | Display Name | Description |
---|---|---|---|---|
IntervalSeconds | int | $Config/IntervalSeconds$ | Interval (seconds) | The recurring interval of time in seconds in which to run the workflow. |
TimeoutSeconds | int | $Config/TimeoutSeconds$ | Timeout (seconds) | Specifies the time the workflow is allowed to run before being closed and marked as failed. |
MinFreeThreadsCount | int | $Config/MinFreeThreadsCount$ | Minimum Free Threads Threshold | The workflow determines the maximum number of threads and the number of active threads for each DB Engine process. An alert will be generated if the number of free threads is less or equal than this parameter. |
NumSamples | int | $Config/NumSamples$ | Number of samples | Indicates how many times a measured value should breach a threshold before the state is changed. |
SyncTime | string | $Config/SyncTime$ | Synchronization Time | The synchronization time specified by using a 24-hour format. May be omitted. |
CacheExpirationTime | int | $Config/CacheExpirationTime$ | Cache Expiration Time | Specifies the maximum age of information from cache the workflow can use. May be omitted. |
