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

ВВЕДЕНИЕ

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

ОБЪЕКТ-МЕНЕДЖЕР

       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.

       Table 1. Killing reasons
       ┌─────────────────┬──────────────────────────┐
       │ Reason          │ Description              │
       ├─────────────────┼──────────────────────────┤
       │ memory-used     │ Application took too     │
       │                 │ much memory and swap.    │
       ├─────────────────┼──────────────────────────┤
       │ memory-pressure │ Application took enough  │
       │                 │ memory and swap to cause │
       │                 │ sufficient slowdown of   │
       │                 │ other applications.      │
       └─────────────────┴──────────────────────────┘

ВЕРСИОНИРОВАНИЕ

       These D-Bus interfaces follow the usual interface versioning
       guidelines[1].
