What are the use of these settings/variables in the Pulse.cfg file?
Also is there any document/ page where we can see the functioning/usage for all the variables of the Pulse.cfg file
We do not have any public documentation yet of the parameters in the Pulse.cfg file. We can look into that though just not with a high priority at the moment.
As for the above those were previously used in Pulse 5 but not in Pulse 6 anymore.
