NAME

       atoprc - atop/atopsar related rcfile

DESCRIPTION

       This  manual page documents the rcfile of the atop and atopsar commands.  These commands can be used to monitor the system and process load
       on a Linux system.

       The atoprc file contains the default settings. These settings are read during startup, first from the system-wide  rcfile  /etc/atoprc  and
       after  that  from the user-specific rcfile ~/.atoprc (so system-wide settings can be overruled by an individual user).  The options in both
       rcfiles are identical.

OPTIONS

       The rcfile contains keyword-value pairs, one on every line (blank lines and lines starting with a #-sign are ignored).
       The following keywords can be specified:

       flags
	   A list of default flags for atop can be defined here. The flags which are allowed are 'g', 'm', 'd', 'n', 'u', 'p', 's', 'c', 'v', 'C',
	   'M', 'D', 'N', 'A', 'a', 'f', '1' and 'x'.

       interval
	   The default interval value in seconds.

       linelen
	   The length of a screen line when sending output to a file or pipe (default 80).

       username
	   The default regular expression for the users for which active processes will be shown.

       procname
	   The default regular expression for the process names to be shown.

       maxlinecpu
	   The maximum number of active CPU's that will be shown.

       maxlinelvm
	   The maximum number of active logical volumes that will be shown.

       maxlinemdd
	   The maximum number of active multiple devices that will be shown.

       maxlinedisk
	   The maximum number of active disks that will be shown.

       maxlineintf
	   The maximum number of active network interfaces that will be shown.

       cpucritperc
	   The	busy  percentage considered critical for a processor (see section COLORS in the man-page of the atop command).	This percentage is
	   used to determine a weighted percentage for line coloring and sorting of active processes.  When this value is zero, no  line  coloring
	   or automatic sorting is performed for this resource.

       dskcritperc
	   The	busy  percentage considered critical for a disk (see section COLORS in the man-page of the atop command).  This percentage is used
	   to determine a weighted percentage for line coloring and sorting of active processes.  When this value is zero,  no	line  coloring	or
	   automatic sorting is performed for this resource.

       netcritperc
	   The	busy  percentage  considered critical for a network interface (see section COLORS in the man-page of the atop command).  This per-
	   centage is used to determine a weighted percentage for line coloring and sorting of active processes.  When this value is zero, no line
	   coloring or automatic sorting is performed for this resource.

       memcritperc
	   The percentage considered critical for memory utilization (see section COLORS in the man-page of the atop command).	This percentage is
	   used to determine a weighted percentage for line coloring and sorting of active processes.  When this value is zero, no  line  coloring
	   or automatic sorting is performed for this resource.

       swpcritperc
	   The occupation percentage considered critical for swap space (see section COLORS in the man-page of the atop command).  This percentage
	   is used to determine a weighted percentage for line coloring and sorting of active processes.  When this value is zero, no line  color-
	   ing or automatic sorting is performed for this resource.

       swoutcritsec
	   The	number	of  pages swapped out per second considered critical for for memory utilization (see section COLORS in the man-page of the
	   atop command).  This threshold is used in combination with 'memcritperc' to determine a weighted percentage for line coloring and sort-
	   ing of active processes.  When this value is zero, no line coloring or automatic sorting is performed for this resource.

       almostcrit
	   A percentage of the critical percentage to determine if the resource is almost critical (see section COLORS in the man-page of the atop
	   command).  When this value is zero, no line coloring for `almost critical' is performed.

       atopsarflags
	   A list of default flags for atopsar can be defined here. The flags that are allowed are 'S', 'x', 'C', 'M', 'H', 'a', 'A' and the flags
	   to select one or more specific reports.

       An example of the /etc/atoprc or ~/.atoprc file:

	       flags	     Aaf
	       interval      5
	       username
	       procname
	       maxlinecpu    4
	       maxlinedisk   10
	       maxlineintf   5
	       cpucritperc   80
	       almostcrit    90
	       atopsarflags  CMH
	       ownprocline   PID:50 VGROW:40 RGROW:45 COMMAND-LINE:50
	       ownpagline    PAGSCAN:3 BLANKBOX:0 PAGSWIN:3 PAGSWOUT:7

       The keywords 'ownprocline' and 'ownpagline' are explained in the subsequent section.

OWN DEFINITION OF OUTPUT LINE

       Via  the  rcfile  it is possible to define the layout of the output lines yourself, i.e. you can define the layout of one line with process
       information with the keyword 'ownprocline' (to be selected with the key 'o' or the flag -o) and you can	redefine  all  lines  with  system
       information.

       The layout of an output-line can be defined as follows (notice that this should be specified as one line in the rcfile):

	  keyword   <columnid>:<prio> [<columnid>:<prio> ...]

       The columnid is the symbolic name of a column that should shown at this position in the output line.
       The  prio is a positive integer value that determines which columns have precedence whenever not all specified columns fit into the current
       screen-width.  The higher value, the higher priority.
       The column-specifications should be separated by a space. The order in which columns have been specified is the order in which they will be
       shown, with respect to their priority (columns that do not fit, will be dropped dynamically).

       A  special  columnid  for  system  lines is 'BLANKBOX'. This indicates that an empty column is required at this position. Also this special
       columnid is followed by a priority (usually low).

       The following definition can be specified for process information:

       ownprocline
	   The columnid's are the names of the columns that are shown in the normal output of the process-related lines that  are  shown  by  atop
	   such  as  'PID',  'CMD',  'S',  ....   The  only  exception	is the special columnid 'SORTITEM' that is used to show one of the columns
	   CPU%/DSK%/MEM%/NET%, depending on the chosen sort-criterium.
	   An example of a user-defined process line:

	       ownprocline   PID:20 PPID:10 SYSCPU:15 USRCPU:15 VGROW:14 VSIZE:12 RGROW:14 RSIZE:12 ST:8 EXC:7 S:11 SORTITEM:18 CMD:20

       The following definitions are used internally by atop as the default system lines (you can redefine each of  them  in  the  rcfile  as  one
       line):

       ownsysprcline
	   Redefinition of line labeled with 'PRC':

	       CVDROP:4 NETSNDDROP:4

       The lines above are shown in the order as shown by atop in combination with the -f flag (in a very wide window you should be  able  to  see
       all of the columns).
