This object is one of a small set of common, reusable varbind definitions meant to be attached to various vendor-specific notifications, and its terse source description simply identifies it as carrying an event's priority level as a plain number. Given how sparse the source description is, an admin should treat the meaning of specific priority numbers as defined by whatever specific trap includes this varbind, rather than assuming a universal severity scale. For example, a trap using this common varbind might carry eventPriority set to 5, whose exact severity meaning depends on the particular notification that includes it.
