расширенный мониторинг системы и процессов (Advanced System and Process Monitor)
PARSEABLE OUTPUT
With the flag -P followed by a list of one or more labels (comma-
separated), parseable output is produced for each sample. The
labels that can be specified for system-level statistics
correspond to the labels (first verb of each line) that can be
found in the interactive output: "CPU", "cpu", "CPL", "GPU",
"MEM", "SWP", "PAG", "PSI", "LVM", "MDD", "DSK", "NFM", "NFC",
"NFS", "NET" and "IFB".
For process-level statistics special labels are introduced: "PRG"
(general), "PRC" (cpu), "PRE" (GPU), "PRM" (memory), "PRD" (disk,
only if "storage accounting" is active).
With the label "ALL", all system and process level statistics are
shown.
For every interval all requested lines are shown whereafter pcp-
atop shows a line just containing the label "SEP" as a separator
before the lines for the next sample are generated.
When a sample contains the values since boot, pcp-atop shows a
line just containing the label "RESET" before the lines for this
sample are generated.
The first part of each output-line consists of the following six
fields: label (the name of the label), host (the name of this
machine), epoch (the time of this interval as number of seconds
since 1-1-1970), date (date of this interval in format
YYYY/MM/DD), time (time of this interval in format HH:MM:SS), and
interval (number of seconds elapsed for this interval).
The subsequent fields of each output-line depend on the label:
