hogs

List the processes that are hogging the CPU

Syntax:

hogs [options] [pids ...]

Runs on:

Neutrino

Options:

-n

Show the names of processes (hogs always displays the process IDs).

-p priority

Run hogs at the given priority (default: the same as the parent process).

-s sec

Sleep this long between updates (default: 3 seconds).

-% num

Show only processes that consume this percentage or more CPU. You can use this option to reduce the amount of output.

Description:

The hogs utility displays a list of processes in descending order by percentage of CPU usage (i.e. it shows who's hogging the processor). It loops forever, sleeping between updates.

The format of the output is tabular, and includes:

PID

The ID of the process being reported.

NAME

The name of the process (included only if you specify the -n option).

MSEC

The number of milliseconds for which this process has been running since the last iteration.

PIDS

The amount of time that the process ran in this iteration, as a percentage of the times of all the other processes running.

SYSTEM

The amount of time that the process ran in this iteration, as a percentage of the iteration time.

Examples:

Display the processes that are using 10% or more of the CPU. Include the name of the processes:

$ hogs -n -% 10
PID             NAME  MSEC  PIDS SYSTEM
1                     2023   78%    67%
8200       devb-eide   384   14%    12%

1                     2456   80%    81%
8200       devb-eide   357   11%    11%

1                     2369   87%    78%

This sample includes three iterations.
