In order to configure a Linux machine you have to edit the /etc/pulseway/config.xml file. Here's a sample configuration:
<?xml version="1.0" encoding="utf-8"?>
<config xmlns="http://www.pulseway.com/linuxconfig">
<!--Pulseway Linux Monitoring Agent - pulseway.com -->
<!--Account Information
- Username: your Pulseway username
- Password: your Pulseway password (the plain password will be automatically encrypted the next time the Pulseway service starts)
