This Gauge32 holds the highest single-sample count of PCIe completion timeouts that UCS Manager observed during any one collection interval within the last 14 days, i.e. a requester (the PCIe root complex or adapter) never received a completion for an outstanding transaction within the PCIe timeout window, captured at its worst moment. Unlike the plain (non-H) gauge for this window, this high-water value stays latched at the worst reading for the rest of the window even if the fault stops recurring, which is what lets an admin catch a brief PCIe error burst that a simple end-of-window snapshot would have missed. For example, if a marginal riser produced a spike of 27 PCIe completion timeouts in one polling cycle and then went quiet, this field would hold 27 until the last 14 days window rolls forward, even though the plain gauge has since dropped to 0.
