NAME

org.freedesktop.oom1 - The D-Bus interface of systemd-oomd

INTRODUCTION

systemd-oomd.service(8) is a system service which implements a userspace out-of-memory (OOM) killer. This page describes the D-Bus interface.

THE MANAGER OBJECT

The service exposes the following interfaces on the Manager object on the bus:

node /org/freedesktop/oom1 {
interface org.freedesktop.oom1.Manager {
methods:
DumpByFileDescriptor(out h fd);
signals:
Killed(s cgroup,
s reason);
};
interface org.freedesktop.DBus.Peer { ... };
interface org.freedesktop.DBus.Introspectable { ... };
interface org.freedesktop.DBus.Properties { ... };
};

Methods
Killed()
signal is sent when any cgroup is killed by oomd.

Note that more reasons will be added in the future, and the table below will be expanded accordingly.
