NAME

       pcp-atopsar - Advanced System Activity Report (pcp-atop related)

SYNOPSIS

       pcp  [pcp options] atopsar [atop options] [-r file|date] [-h host] [-R cnt] [-b hh:mm] [-e
       hh:mm]
       pcp [pcp options] atopsar [atop options] interval [samples]

DESCRIPTION

       The pcp-atopsar program can be used to report statistics at the system level.

       In the first synopsis line (no sampling interval  specified),  pcp-atopsar  extracts  data
       from  a raw logfile that has been recorded previously by pmlogger(1) (or via the -w option
       of the pcp-atop program).
       You can specify the name of the logfile with the -r option  of  the  pcp-atopsar  program.
       When  a pmlogger daily logfile is used, named $PCP_LOG_DIR/pmlogger/[host]/YYYYMMDD (where
       YYYYMMDD reflects the date), the required date of the form YYYYMMDD can be specified  with
       the  -r  option  instead  of  the  filename,  or  the  symbolic  name  'y' can be used for
       yesterday's daily logfile (this can be repeated so 'yyyy' indicates the  logfile  of  four
       days  ago).   If  the  -r option is not specified at all, today's daily logfile is used by
       default.
       By default, the hostname of the localhost will be used when resolving  pmlogger  archives,
       however an alternative host can be specified using the -h option.
       The  starting  and  ending  times of the report can be defined using the options -b and -e
       followed by a time argument of the form hh:mm.

       In the second synopsis line, pcp-atopsar reads actual activity counters  from  the  kernel
       with the specified interval (in seconds) and the specified number of samples (optionally).
       When pcp-atopsar is activated in this way  it  immediately  sends  the  output  for  every
       requested  report to standard output.  If only one type of report is requested, the header
       is printed once and after every interval seconds the statistical counters  are  shown  for
       that period.  If several reports are requested, a header is printed per sample followed by
       the statistical counters for that period.

       When invoked via the pcp(1) command,  the  PCPIntro(1)  options  -h/--host,  -a/--archive,
       -O/--origin,  -s/--samples,  -t/--interval,  -Z/--timezone  and  several other pcp options
       become indirectly available.

       Some generic flags can be specified to influence the behaviour of the pcp-atopsar program:

       -S   By default the timestamp at the beginning of a line is suppressed if more  lines  are
            shown  for  one  interval.  With this flag a timestamp is given for every output-line
            (easier for post-processing).

       -a   By default certain resources as disks and network interfaces are only shown when they
            were  active  during  the interval.  With this flag all resources of a given type are
            shown, even if they were inactive during the interval.

       -x   By default pcp-atopsar only uses colors if output is directed to a terminal (window).
            These  colors  might  indicate that a critical occupation percentage has been reached
            (red) or has been almost reached (cyan) for a particular resource.  See the  man-page
            of atop for a detailed description of this feature (section COLORS).
            With the flag -x the use of colors is suppressed unconditionally.

       -C   By default pcp-atopsar only uses colors if output is directed to a terminal (window).
            These colors might indicate that a critical occupation percentage  has  been  reached
            (red)  or has been almost reached (cyan) for a particular resource.  See the man-page
            of atop for a detailed description of this feature (section COLORS).
            With the flag -C colors will always be used, even if output  is  not  directed  to  a
            terminal.

       -M   Use  markers  at  the end of a line to indicate that a critical occupation percentage
            has been reached ('*') or has been almost reached ('+') for particular resources. The
            marker  '*' is similar to the color red and the marker '+' to the color cyan. See the
            man-page of atop for a detailed description of these colors (section COLORS).

       -H   Repeat the header line within a report for every N detail lines. The value  of  N  is
            determined  dynamically in case of output to a tty/window (depending on the number of
            lines); for output to a file or pipe this value is 23.

       -R   Summarize cnt samples into one sample. When the logfile contains e.g. samples  of  10
            minutes, the use of the flag '-R 6' shows a report with one sample for every hour.

       Other flags are used to define which reports are required:

       -A   Show all possible reports.

       -c   Report about CPU utilization (in total and per cpu).

       -g   Report about GPU utilization (per GPU).

       -p   Report about processor-related matters, like load-averages and hardware interrupts.

       -P   Report about processes.

       -m   Current memory- and swap-occupation.

       -s   Report about paging- and swapping-activity, and overcommitment.

       -B   Report about Pressure Stall Information (PSI).

       -l   Report about utilization of logical volumes.

       -f   Report about utilization of multiple devices.

       -d   Report about utilization of disks.

       -n   Report about NFS mounted filesystems on NFS client.

       -j   Report about NFS client activity.

       -J   Report about NFS server activity.

       -i   Report about the network interfaces.

            available when using a log file (not when specifying an interval).

       -G   Report about top-3 processes consuming most resident memory.   This  report  is  only
            available when using a log file (not when specifying an interval).

OUTPUT DESCRIPTION

       Depending  on  the  requested report, a number of columns with output values are produced.
       The values are mostly presented as a number of events per second.

       The output for the flag -c contains the following columns per cpu:

       usr%        Percentage of cpu-time consumed in user mode (program  text)  for  all  active
                   processes running with a nice value of zero (default) or a negative nice value
                   (which means a higher priority than usual).  The cpu consumption in user  mode
                   of  processes with a nice value larger than zero (lower priority) is indicated
                   in the nice%-column.

       nice%       Percentage of cpu time consumed in user  mode  (i.e.  program  text)  for  all
                   processes running witn a nice value larger than zero (which means with a lower
                   priority than average).

       sys%        Percentage of cpu time consumed in system mode (kernel text)  for  all  active
                   processes.  A  high  percentage  usually indicates a lot of system calls being
                   issued.

       irq%        Percentage of cpu time consumed for handling of device interrupts.

       softirq%    Percentage of cpu time consumed for soft interrupt handling.

       steal%      Percentage of cpu time stolen by other virtual machines running  on  the  same
                   hardware.

       guest%      Percentage  of  cpu  time  used  by other virtual machines running on the same
                   hardware (overlaps with usr%/nice%).

       wait%       Percentage of unused cpu time while at least one of  the  processes  in  wait-
                   state awaits completion of disk I/O.

       idle%       Percentage  of  unused  cpu time because all processes are in a wait-state but
                   not waiting for disk-I/O.

                   and  write accesses issued on disk by all processes, so a high percentage does
                   not imply a high disk load on system level.

EXAMPLES

       To see today's cpu-activity so far (supposed that atop is logging in the background):

         pcp-atopsar

       To see the memory occupation for June 5, 2018  between  10:00  and  12:30  (supposed  that
       pmlogger has been logging daily in the background on host acme.com):

         pcp-atopsar -m -r $PCP_LOG_DIR/pmlogger/acme.com/20180605 -b 10:00 -e 12:30

                       or

         pcp-atopsar -m -r 20180605 -b 10:00 -e 12:30

                       or, suppose it is June 8, 2018 at this moment

         pcp-atopsar -m -r yyy -b 10:00 -e 12:30

       Write a logfile with atop to record the system behaviour for 30 minutes (30 samples of one
       minute) and produce all available reports afterwards:

         pcp-atop -w /tmp/atoplog 60 30

         pcp-atopsar -A -r /tmp/atoplog

       To watch TCP activity evolve for ten minutes (10 samples with sixty seconds interval):

         pcp-atopsar -t 60 10

       To watch the header-lines ('_' as last character) of all reports  with  only  the  detail-
       lines showing critical resource consumption (marker '*' or '+' as last character):

         pcp-atopsar -AM | grep '[_*+]$'
