    0. Common zram settings

    See https://www.kernel.org/doc/Documentation/blockdev/zram.txt
    You maybe need $IGNORE_ZRAM=FALSE if you has a big zram disksize

$IGNORE_ZRAM = TRUE

    1. Common PSI settings

    See
    https://lwn.net/Articles/759658/
    https://facebookmicrosites.github.io/psi/

$IGNORE_PSI = TRUE

$PSI_PATH = /proc/pressure/memory

    some_avg10 is most sensitive.

$PSI_METRICS = some_avg10

$PSI_EXCESS_DURATION = 0

$PSI_POST_ACTION_DELAY = 40



    2. Poll rate

$FILL_RATE_MEM  = 4000
$FILL_RATE_SWAP = 1500
$FILL_RATE_ZRAM =  500
$MIN_SLEEP = 0.1
$MAX_SLEEP = 3


    3. Warnings / GUI notifications

$GUI_CORRECTIVE_ACTIONS  = FALSE

$GUI_LOW_MEMORY_WARNINGS = FALSE
$GUI_WARNINGS_MIN_MEM  = 20 %
$GUI_WARNINGS_MIN_SWAP = 20 %
$GUI_WARNINGS_MAX_ZRAM = 45 %
$GUI_MIN_DELAY_AFTER_WARNING = 15

@EXE_INSTEAD_OF_GUI_WARNING wall -n "LOW MEMORY!"
@EXE_INSTEAD_OF_GUI_WARNING echo 'test'


    4. Soft threshold / SIGTERM-related parameters

$SOFT_MIN_MEM_THRESHOLD     = 10 %
$SOFT_MIN_SWAP_THRESHOLD    = 10 %
$SOFT_MAX_ZRAM_THRESHOLD    = 50 %

$SOFT_POST_ACTION_DELAY = 0.2

$MAX_POST_SOFT_ACTION_VICTIM_LIFETIME = 9

$SOFT_MAX_PSI_THRESHOLD = 60
$SOFT_MAX_PSI_DURATION = 5

    The execution of specified command instead of sending the SIGTERM signal.
    Syntax example:
    <key>                     <regular expression>  ///  <command>

@EXE_INSTEAD_OF_SIGTERM_RE_NAME  ^foo$       ///  kill -9 $PID && echo "Praise KEK, kill $NAME" &

@EXE_INSTEAD_OF_SIGTERM_RE_CMDLINE      ^/sbin/foo  ///  systemctl restart foo

@EXE_INSTEAD_OF_SIGTERM_RE_REALPATH     ^/sbin/bar$ ///  systemctl restart foo

@EXE_INSTEAD_OF_SIGTERM_RE_UID          ^1000$      ///  pkill -SEGV $NAME
@EXE_INSTEAD_OF_SIGTERM_RE_UID          ^1001$      ///  pkill -HUP $NAME

@SOFT_THRESHOLD_EXE_RE_NAME

    5. Hard threshold / SIGKILL-related parameters

$HARD_MIN_MEM_THRESHOLD  =  5 %
$HARD_MIN_SWAP_THRESHOLD =  5 %
$HARD_MAX_ZRAM_THRESHOLD = 55 %

$POST_KILL_EXE = 

$HARD_POST_ACTION_DELAY = 1

$HARD_MAX_PSI_THRESHOLD = 90
$HARD_MAX_PSI_DURATION = 5


$POST_KILL_EXE =



    6. Adjusting badness of processes

$OOM_SCORE_ADJ_LIMIT = -1

    Badness adjusting by matching process name, cmdline and eUID with specified regular expression.

    Example badness adj rules
    <key>                  <regular expression>    ///   <badness_adj>

@BADNESS_ADJ_RE_CMDLINE  -childID|--type=renderer  ///   200

@BADNESS_ADJ_RE_NAME     ^Xorg$                    ///  -100

@BADNESS_ADJ_RE_UID      ^0$                       ///   -50

@BADNESS_ADJ_RE_REALPATH   ^/usr/bin/tail$         ///   100



    7. Avoid killing small processes (innocent victims)

$MIN_VICTIM_BADNESS = 20
