ID: 10907 Title: ucd_cpu_util: Fix CPU utilization calculation Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 Fixed the calculation for the CPU utilization. The system value used the outdated values/OIDs. No longer query the CpuRawKernel value, since its already included in the CpuRawSystem. CpuRawSystem = CpuRawKernel + CpuRawWait The system value gets computed as: system = CpuRawSystem + CpuRawInterrupt + CpuRawSoftIRQ (CpuRawInterrupt in this case is equal to IRQ)
