Events are the fruit of our monitoring labor, and event handling is one of the primary ways we can turn the raw monitoring data into actionable items. For example, we review the event history of a device to identify trends. Event commands provide a way to automate actions when a certain event happens, and the breadth of what you can do with event commands is only limited by your imagination and programming knowledge. In the next chapter, we will also collect events from external sources and create alerting rules.
Event mappings route the event to the event class and in the process, the event inherits properties, such as severity. In the next chapter, we'll see how we can manipulate the properties of an event with transformations.
