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. |
SyncTime | string | $Config/SyncTime$ | Synchronization Time | The synchronization time specified by using a 24-hour format. May be omitted. |
Threshold | int | $Config/Threshold$ | Threshold | The collected ratio will be compared against this parameter. |
CfpCountThreshold | int | $Config/CfpCountThreshold$ | Checkpoint File Pairs Threshold | An alert would be generated if Checkpoint File Pairs total count greater than or equal to the Checkpoint File Pairs Threshold. |
SqlTimeoutSeconds | int | $Config/SqlTimeoutSeconds$ | Timeout for database connection (seconds) | The workflow will fail and register an event, if it cannot access the database during the specified period. |
TimeoutSeconds | int | $Config/TimeoutSeconds$ | Timeout (seconds) | Specifies the time the workflow is allowed to run before being closed and marked as failed. |
NumSamples | int | $Config/NumSamples$ | Number of samples | Indicates how many times a measured value should breach the thresholds before the state is changed. |
