Hi Duncan.  Please compile this code  interface CPU_Performance_Alaxala6300 : Processor_Performance {         instrument SNMP {                   cpuUtil = "1.3.6.1.4.1.21839.2.2.8.2.2.1.1.16.1"         };          readonly instrumented attribute int cpuUtil         "Percentage of CPU Utilisation";          refine computed CurrentUtilization         = cpuUtil; }  and insert next section to OID2Type.conf file (note: ENVIRONMENTS not included to this section)  .1.3.6.1.4.1.21839.1.2.8 {     TYPE = Switch     VENDOR = Alaxala     CERTIFICATION = TEMPLATE     CONT = Alaxala-6300     VLAN = Dot1q   INSTRUMENTATION:     Interface-Fault             = MIB2     Interface-Performance       = MIB2     Port-Fault                  = MIB2     Port-Performance            = MIB2     Port-Ethernet-Performance   = dot3_Ethernet     CPU/Memory                  = Alaxala6300:DeviceID }  Code not tested but it should work :-)  Also is important how u create Processor object in Containment drivers, please note that u fill DeviceID attribute.

I have a custom device that I have created the containment drivers for.   The device is now discovered with all of the component objects and their relationship(s) set correctly.   I now need to populate the values of the object attributes, among them the CurrentUtilization value of the Processor.  I can retrieve the value using SNMP but am unable to insert the value using dmctl using put or insert (see below)  dmctl> insert Processor::PSR-10.2.0.178/1::CurrentUtilization 77 CurrentUtilization: Can't perform set operation on scalar attribute   dmctl> put  Processor::PSR-10.2.0.178/1::CurrentUtilization 77 CI-E-EGENERIC-At     /work/bluecurrent/FOUNDATION-7.0.2.X-HF/106/smarts/repos/mr/prop.c:277     put: Attempted to call access method which is not available for given     attribute  MR-UNAVAILABLE_ACCESS_METHOD-Attempted to call access method which is not     available for given attribute   Could somebody please assist with a means of populating this attribute?   Thanks,   Duncan
