Описание (Description)
The pidstat command is used for monitoring individual tasks
currently being managed by the Linux kernel. It writes to
standard output activities for every task selected with option -p
or for every task managed by the Linux kernel if option -p ALL
has been used. Not selecting any tasks is equivalent to
specifying -p ALL but only active tasks (tasks with non-zero
statistics values) will appear in the report.
The pidstat command can also be used for monitoring the child
processes of selected tasks. Read about option -T below.
The interval parameter specifies the amount of time in seconds
between each report. A value of 0 (or no parameters at all)
indicates that tasks statistics are to be reported for the time
since system startup (boot). The count parameter can be specified
in conjunction with the interval parameter if this one is not set
to zero. The value of count determines the number of reports
generated at interval seconds apart. If the interval parameter is
specified without the count parameter, the pidstat command
generates reports continuously.
You can select information about specific task activities using
flags. Not specifying any flags selects only CPU activity.
