Configuring Data Stream Thresholds
A key feature of the Ayyeka system is the ability to configure multiple thresholds for any data stream, and specify
actions such as alerts when data samples cross a threshold.
Thresholds are configured using ranges of values bound by a lower and upper limit. Let’s say you want to
configure thresholds for a Temperature data stream. You can define a Low threshold of 0-40°F, a Normal
threshold of 40-120°F, and a High threshold of 120-250°F. For each threshold range, you can configure Actions
the Wavelet device should perform when data samples cross into a threshold range, such as modifying the
sampling or transmission frequency, or sending email and/or SMS alerts to certain users.
Accessing the threshold view
In a nutshell:
1. Click Devices in the sidebar.
2. In the Sites Tree pane select the stream.
3. In the right pane select the Thresholds tab.
4. If the Thresholds slider is OFF , click it to switch Thresholds to ON .
To view or set a data stream’s thresholds:
1. Click Devices in the sidebar, and click the stream name in the Sites Tree pane.
2. In the right pane, select the Thresholds tab.
3. If the Thresholds slider is in the OFF position , click it to switch Thresholds to ON .
A graph appears, showing the data stream values for the past week (use the Time Frame slider to zoom in
or out).
The thresholds defined for this data stream are displayed below the graph.
By default, the system creates three ranges for each data stream: Low, Normal and High.
The thresholds cover the entire spectrum of actual stream values collected by the device.
