For detailed information about the appropriate description of the various supported CPUs and VMs, refer to Terminology.

The system monitor (SYSMON) collects CPU or VM usage data measurement entries with corresponding time stamps.

Note

For the DSC 8000, the data measurement entries are up to 32 CPU cores on each card.

On the DSC 8000 CPUs, only existing CPU cores (physicals and virtual cores) are assigned columns in the SYSMON data measurement file with valid values. On the VMs, only existing VM cores (physicals and virtual cores) are assigned columns in the SYSMON data measurement file with valid values. All remaining data measurement columns are assigned a value of zero.

The SYSMON application reads CPU or VM usage from the /tmp/.cpu_usage.txt file every ten seconds and then keeps track of the average value over a period of five minutes. The SYSMON data measurement file also includes the CPU or VM Usage Read Count which indicates the number of CPU or VM usage performed by SYSMON over the period of the five-minute interval.

The following figure shows an example for the CPU measurements:

The instance represents the application object that generates the data measurements. The CPU or VM usage instance value is formatted as follows:
