Table 32 Units and Terminology (continued)
The amount of memory used in gigabytes (2^30 bytes).
Each sample represents an actual reading at the time the sample was taken. These measurements
are obtained and calculated in the following manner:

/proc/statMemory used by the usersLinux
Memory used by the users + memory

sys$getrmi system service
(RMI$_USERPAGES) and
Sys$getsyi
(syi$_PhysicalPages)
Total memory used by user and system
processes.
OpenVMS
memory utilization
The ability of an application and operating system to split processing between processors or
cores, thereby enabling parallel computing.
multithreading
Measured in Mb/s (10^6 bits, megabits per second).
Each sample represents an average reading over the past five minutes. These measurements
are obtained and calculated in the following manner:

network I/O
bandwidth utilization
The system-name.OTHER workload is used to account for all processes on a system that do
not match any user-defined workloads. For more information, see Workloads“Workloads” in
visualization help. On some Capacity Advisor displays, data is not available for this .OTHER
workload.
OTHER workload
Component that plugs into a processor socket. A processor can contain more than one core.processor
The packaging of one or more processors in a unit that connects to a single socket on the system
bus.
processor module
The system board socket to which a processor is attached.processor socket
A compensating factor that Capacity Advisor uses to adjust needed resources when analyzing
a move from one platform to another.
