IDParameterTypeSelectorDisplay NameDescription
IntervalSecondsint$Config/IntervalSeconds$Interval (seconds)The recurring interval of time in seconds in which to run the workflow.
TimeoutSecondsint$Config/TimeoutSeconds$Timeout (seconds)Specifies the time the workflow is allowed to run before being closed and marked as failed.
Thresholdint$Config/Threshold$ThresholdThe collected value will be compared against this parameter.
AzureMaxFileSizeMBint$Config/AzureMaxFileSizeMB$Azure Maximum File Size (MB)The maximum size of data file stored in Azure BLOB Storage. The workflow will consider this value as a maximum storage capacity for each file.
NumSamplesint$Config/NumSamples$Number of samplesIndicates how many times a measured value should breach a threshold before the state is changed.
