This read-only SnmpAdminString field is the 'load' property of the 'FexSystemStatsHist' managed object in Cisco UCS Manager's equipment-inventory schema recording the FEX's control-plane CPU load-average string at the moment this historical sample was archived. This preserves a specific past load reading for the FEX's own embedded CPU, letting an admin look back and confirm whether the supervisor was under heavy load at a specific earlier time, such as right before it stopped responding to SNMP polls. An archived Load of '6.20 5.80 4.10' just before a monitoring gap would point to CPU saturation on the FEX supervisor as the likely cause of the missed polls.
