Event Simulator

The Event Simulator Listener is used to simulate a constant flow of random data.

You would use this Agent when testing or developing a data stream - until accurate data from a more specialized source is required.

Please consider your needs carefully when choosing between the CSV Listener and the Event Simulator.

Pros:

• It is faster to set up than a CSV Reader if you do not already have a CSV file with the data you require.

• It can generate a random value rather than a fixed value per record

• It can send an unlimited number of records.

Cons:

• The time interval between record batches is set to one second and cannot be changed.

• You cannot send a variety of values for any type other than Double.

Details for an example and its configuration can be found in the How to Use section.
