sdkperf file input format
I am trying to test my application with sdkperf to control the number of messages published per second and I am finding the sdkperf_c tool very useful, however the documentation doesn't explain clearly how to structure the text file when using the -sdm option. I would like to send a message containing a string, and defining peroperties under UserPropertyMap. I would also like to understand better the structure of the message in the example file. Are there any resources about this?
