This Gauge32 reports the count of PCIe completion aborts accumulated specifically within the last 14 days — that is, the receiving PCIe device could not satisfy a request and returned a Completer Abort instead of valid data — and rolls forward on that period rather than accumulating forever like the base Counter32 for this error type. A rising value here (rather than a flat one inherited from months ago) is what tells an admin that this specific PCIe error is happening right now and worth an immediate look, not just a historical scar. For example, seeing this climb from 22 to 25 across two SNMP polls during the last 14 days window would point to an active, ongoing PCIe fault on this component rather than a one-time event from long ago.
