We already have an interface for this, it's documented here: https://systemd.io/MEMORY_PRESSURE It doesn't operate via D-Bus however, but instead just tells apps how to directly get the events from the kernel. That's generally better than bumping the events off two daemons (i.e. a memory pressure daemon and a dbus broker), simply because memory pressure is a problem of latency, and you should not add additional steps to the notifications if you want to make things better and not worse. Moreover, on memory pressure you shouldn't allocate more memory, which is something the indirection through a daemon and broker would typically mean. > We are looking for a new backend for GMemoryMonitor. > https://developer-old.gnome.org/gio/stable/GMemoryMonitor.html > > The original backend- low-memory-monitor monitors the system memory > usage.

It should be possibly to implement a GMemoryMonitor on top of the kernel APIs directly, using the information systemd gives you. See the documentation. It even briefly mentions GMemoryMonitor at the end. If you have any questions about details, feel free to ask! Lennart -- Lennart Poettering, Berlin
[systemd-devel] Low memory dbus signal for GMemoryMonitor
Hi Folks, Could systemd detect the system's low memory status and send a signal through Dbus about low memory events? We are looking for a new backend for GMemoryMonitor. https://developer-old.gnome.org/gio/stable/GMemoryMonitor.html The original backend- low-memory-monitor monitors the system memory usage. When it detects the memory is lower than a level, it signals the application. It also manages the kernel OOM. Thank you :) -- BR, Kate

Please research your subjects, docker, AD, sshd, try a few things, show us the service files you have created and the output. Also include the systemd version you use, and the operating system flavour and versions. We will help you fix issues in your files, but you have to come up with them in the first place.
