Earlyoom
services.earlyoom.enable
Whether to enable early out of memory killing.
Type: boolean
Default
false
Example
true
Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/system/earlyoom.nix
services.earlyoom.enableDebugInfo
Enable debugging messages.
Type: boolean
Default
false
Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/system/earlyoom.nix
services.earlyoom.enableNotifications
Send notifications about killed processes via the system d-bus.
WARNING: enabling this option (while convenient) should not be done on a machine where you do not trust the other users as it allows any other local user to DoS your session by spamming notifications.
To actually see the notifications in your GUI session, you need to have
systembus-notify running as your user, which this
option handles by enabling {option}services.systembus-notify.
See README for details.
Type: boolean
Default
false
Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/system/earlyoom.nix
services.earlyoom.extraArgs
Extra command-line arguments to be passed to earlyoom.
Type: list of string
Default
[ ]
Example
["-g""--prefer '(^|/)(java|chromium)$'"]
Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/system/earlyoom.nix
services.earlyoom.freeMemKillThreshold
Minimum available memory (in percent) before sending SIGKILL.
If unset, this defaults to half of {option}freeMemThreshold.
Type: null or integer between 1 and 100 (both inclusive)
Default
null
Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/system/earlyoom.nix
services.earlyoom.freeMemThreshold
Minimum available memory (in percent).
If the available memory falls below this threshold (and the analog is true for
{option}freeSwapThreshold) the killing begins.
SIGTERM is sent first to the process that uses the most memory; then, if the available
memory falls below {option}freeMemKillThreshold (and the analog is true for
{option}freeSwapKillThreshold), SIGKILL is sent.
See README for details.
Type: integer between 1 and 100 (both inclusive)
Default
10
Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/system/earlyoom.nix
services.earlyoom.freeSwapKillThreshold
Minimum free swap space (in percent) before sending SIGKILL.
If unset, this defaults to half of {option}freeSwapThreshold.
Type: null or integer between 1 and 100 (both inclusive)
Default
null
Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/system/earlyoom.nix
services.earlyoom.freeSwapThreshold
Minimum free swap space (in percent) before sending SIGTERM.
Type: integer between 1 and 100 (both inclusive)
Default
10
Declared by: https://github.com/nixos/nixpkgs/blob/master/nixos/modules/services/system/earlyoom.nix
services.earlyoom.killHook
An absolute path to an executable to be run for each process killed. Some environment variables are available, see README and the man page for details.
Type: null or path
Default
null
Example
pkgs.writeShellScript "earlyoom-kill-hook" '' echo "Process $EARLYOOM_NAME ($EARLYOOM_PID) was killed" >> /path/to/log''
