This object is another of this MIB's generic, reusable common varbinds, intended to carry a running count of events when attached to a vendor-specific trap, and its source description is minimal, simply labeling it as an event counter. An admin uses it, in whatever specific trap includes it, to see how many times a particular type of event has occurred since the counter was last reset or the device last rebooted. For example, a trap using this common varbind might carry eventCounter at 42, indicating the associated event type has fired 42 times so far.
