Figure 1: Task Usage
The Task Usage table is updated every ten seconds.
The following output is displayed:
Table 1: Task Usage Information
Parameter | Description |
---|---|
PID | Specifies the process ID. |
USER | Specifies the owner of the process. |
PR | Specifies the priority of the process. |
NI | Specifies the NICE value of the process. |
VIRT | Specifies the virtual memory used by the process. |
RES | Specifies the physical memory used by the process. |
SHR | Specifies the shared memory used by the process. |
S | Specifies the status of the process. The following are the values:
|
%CPU | Specifies the percentage of CPU used by this process. |
%MEM | Specifies the percentage of memory (RAM) used by the process. |
TIME+ | Specifies the total time activity of this process. |
COMMAND | Specifies the name of the process. |
For applications using Linux kernel version 3.16 or higher (for example, SBC v06.02.00 and higher), the output of the top
command displays wrong, and sometimes unrealistic, values about CPU utilization. This is a known issue with all 3.16 and higher kernels (refer to this CentOS page for more information).
Likewise, the information and graphs displayed in this EMA window may display wrong values of CPU utilization.
You can use top -H
or mpstat
commands to check the memory and CPU utilization.
