An actionable notification is a push notification with one or more action buttons.
Selecting an action button usually has an immediate action associated with it.
When sending an actionable notification from the Simplepush Node-RED node, the immediate result of selecting an action is that the node will forward the action name to its msg.payload
output.
This creates the potential to execute different subflows based on which action was selected by the user.
Sometimes proper server monitoring is just not worth the effort. However it can still be useful to know when a disk on your server starts to become full.
