Introduction


Data in Motion and IoT• The Internet of Things (IoT) is a computing concept that describes a future

where everyday physical objects will be connected to the Internet and be able to identify themselves to other devices.

• Cisco Data in Motion (DMo) is a software technology that provides data management and first-order analysis at the edge.

• Cisco Data in Motion provides mechanisms to capture data and control flows within the network translating data into information and ultimately into knowledge for use by higher order applications within a system.

Programming Data in Motion


Data In Motion Model (details)• Context: Sandbox for an

application with separate URP allowing for the creation and interaction of multiple data analysis operations.

• Dynamic Data Definitions (aka D3): A set of patterns, rules, and actions for a specific analysis task. Multiple D3s may exist within a single context and reference each other for compound or recursive analysis.

relationship of three simple concepts

Data in Motion API as an Open Source Project• Krikkit initiative originates from Cisco

Data in Motion project

Promotion of Data in Motion products and Data in Motion proliferation across industry

Maintain Leadership in industry for IoT efforts IoT does not have many Standards and Open

Source is way to accelerate IoT innovations with Cisco products

Krikkit is the public API for Data in Motion

Create Hello World with Data in Motion


Login To DMo

Login PagePoint your browser to the IP address unique to your workstation

http://[your unique IP]:8000

Requires an IP address of the DMo instance, the port number, a context and the associated password:

IP: 127.0.0.1 Port: 443Context Name: dmolabContext Password: dmo123


Clean StartAn Empty ContextWe need to make sure there are no pre-existing rules.

A Programmed Context

if your screen looks similar to the screen below, please click the Trash Can Icon and Delete rules.


Create a Timer Rule

Polling a SensorMost Real life sensors are Asynchronous, as a result, we need to create a timer rule that will poll the sensors to retreive the Data.

A timer rule is a process that runs periodically (units in millseconds and above) and estabishes a connection to the sensor.


Verifying the Timer Rule

The JSON Payloadif you want to see what the resulting JSON code would look like, you can press the 'see JSON' button.


Create an Event Rule

Turn LED ONNow that we have Setup a Timer Rule and we are polling the Sensors for Data.

We will need to create an Event Rule to apply a filter to the data coming back from the sensor and take action depending on the data value.

• Filter Data• Turn LED OFF [output Port0] when light Sensor

[input Port1] is Dimmed [Value < 100]


Create another Event Rule

Turn LED OFFNow that we have turned the LED ON when Dimming the light on the sensor, we would like to turn the LED back off when the Light Sensor is lit

• Filter Data• Turn LED OFF [output Port0] when light Sensor

[input Port1] is not Dimmed [Value > 100]


Bonus Lab• Setup a Rule that will turn the LED ON when Pressing on the Pressure Sensor

[Pressure Threshold > 10]

• Setup another Rule that will turn the LED OFF when depressing the Pressure Sensor [Pressure Threshold < 10]

• Useful Information

• LED is on [Output Port 1]

• LED value 0 Turns OFF

• LED value 1 Turns ON

• Pressure Sensor is on [Input Port 1]
