I'm trying to use SNMP to record the "Disk Util" percentage numbers that are given by the sysstat command. The MIB doesn't present this number directly. The sysstat man page defines "Disk Util" as "The disk utilization (percentage) of the busiest disk", but I can't find any OIDs from which I could derive this. Does anyone know what to read and calculate in SNMP to obtain this number?
