Logging is a critical part of any embedded development framework. Most devices can't display error or warning messages and don't have a human user monitoring them. Even when a device does have a display and a user watching it, the log messages often don't help the device's primary user. Displaying messages on a screen doesn't support remote troubleshooting; especially when the device is hidden from view inside a piece of equipment or located in remote geographic regions.
