Dimension and Tree Objects

Start with the dimension and tree objects. The dimensions describe the fields of your data that are used for grouping and the tree the relation between them. The identifying fields in the input data are region and country. A region has one or more countries. The data type is sales. In the dimension object we specify each of our identifying fields as separate objects, with the datatype and field.

Configuring Dimensions and Tree

Metrics

Define the metrics using the amount field in the input data:

• totalSales - For total sales, sum up the amount for each record by using the sum function on the expression expr, which contains the amount field. 
• avgSales  - For average sales  use the avg function instead of sum.
• numSales - To count the number of records, use the conditional function isSet in the expression. This function evaluates to 1 if there is a value in amount or 0 if there is no value. Use the function sum to sum up the 1s and 0s.

Configuring Metrics

KPIs

Define the KPIs. The expected output is the total sales, average sales, and number of sales per region and country in 60 second periods. 

Use the  property node to describe where in the topology the KPI should be calculated and windowSize to set the period length. Use the names of the metrics defined above in the expr property.  

Configuring KPIs

Completing and Saving the Profile

Select the Aggregated Output checkbox and set the Window Size to 60, and Save the profile with the name "SalesModel" in the folder "kpisales".

Add Pulse Agents and Analysis agent

Add three Pulse agents and an Analysis agent.
 

Workflow - Pulse Agents

Configure the Pulse agents as follows:

• AMERICAS will send 1000 TPS -  Set Time Unit to MILLISECONDS and Interval to 100
• EMEA will send 500 TPS - Set Time Unit to MILLISECONDS and Interval to 200
• APAC will send 250 TPS - Set Time Unit to MILLISECONDS and Interval to 400

To be able to identify the data, set the data to the region name. 

Pulse agent configuration

The Pulse agents only sends us a simple event containing the name of the region, the other data that will be used in the KPI calculations are generated in the connected Analysis agent.

In the Analysis agent, click on the Set to Input button beneath UDR Types and paste the APL code below to create the input to KPI Management.

Adding KPI Agent

Add a KPI agent and configure it to use the KPI profile that you created in step 1. Set Delay to 0.

Adding an Analysis Agent for Debug

Add another Analysis agent for debugging of the KPIs. 

Final workflow configuration 

In the Analysis agent, click on the Set to Input button beneath UDR Types and paste the APL code below to the Analysis agent.

Save the workflow.

Open Workflow in Monitor

Open the workflow configuration in the Workflow Monitor. Enable debugging and select events for the KPI agent and the Analysis agent that produces the debug output.

Starting the Workflow

Ensure to have an ec running and click on the Start button.

Viewing Result

The calculated KPIs will be displayed in the debug output in the Workflow Monitor.
