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', 'y', 'f',
'F', 'G', 'R', '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.
maxlinenfsm
The maximum number of NFS mounts that will be shown on an NFS client.
maxlineintf
The maximum number of active network interfaces that will be shown.
maxlinecont
The maximum number of active containers 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 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.
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 coloring 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 sorting 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.
colorinfo
Definition of color name for information messages (default: green).
Allowed colors are: red green yellow blue magenta cyan black white.
colorthread
Definition of color name for thread-specific lines when using the 'y' option (default:
yellow).
Allowed colors are: red green yellow blue magenta cyan black white.
coloralmost
Definition of color name for almost critical resources (default: cyan).
Allowed colors are: red green yellow blue magenta cyan black white.
colorcritical
Definition of color name for critical resources (default: red).
Allowed colors are: red green yellow blue magenta cyan black white.
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.
pacctdir
The name of the topdirectory used by the atopacctd daemon. In this directory, the
daemon creates a subdirectory pacct_shadow.d in which files will be written containing
the process accounting records. The default topdirectory is /run and this option only
has to be specified when the atopacctd daemon is started with an alternative
topdirectory as command line argument.
This option can only be specified in the /etc/atoprc file (on system level)!
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 PRCSYS:8 PRCUSER:8 BLANKBOX:0 PRCNPROC:7 PRCNZOMBIE:5 PRCCLONES:4
