Hello! I am using systemd and repeatedly need to do the following: - Start a process with memory limit and cpu affinity; - Be notified when it and all its children are finished (typically in 0.01-1 second); - Get cpu and memory usage statistics.
Cgroups look perfect for me, but what is the best way of managing them? As far as I understand, ControlGroupInterface article advises to create a transient scope unit for each process I run, but I need to preserve cpu accounting information, so scope units will not work. Alternatively, I could create service units, but I am concerned with performance issues and would like to create processes by myself. Are any lower-level APIs available and advised to use? For example, I'd be happy to create a slice using systemd, create its subtrees manually and manage them myself, but the aforementioned article does not recommend it. Thanks, Boris. _______________________________________________ systemd-devel mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/systemd-devel
