Previously, the CPU load service was not discovered on Skyhigh Secure Web Gateway devices. These devices expose CPU load data via UCD-SNMP-MIB OIDs, but the SNMP detection rule for ucd_cpu_load did not match them. After upgrading from 2.2 to 2.3, any custom workaround packages stopped working and the service would go stale or vanish after a tabula rasa.

A dedicated SNMP section now detects Skyhigh Secure Web Gateway devices and fetches their CPU load data, making the CPU load service discoverable again.
