NAME

       oomd - Userspace Out-Of-Memory (OOM) killer for Linux systems

SYNOPSIS

       oomd [OPTION] ...

DESCRIPTION

       oomd  leverages  PSI and cgroupv2 to monitor a system holistically.  oomd then takes corrective action in
       userspace before an OOM occurs in kernel space. Corrective action is configured  via  a  flexible  plugin
       system,  in which custom code can be written. By default, this involves killing offending processes. This
       enables an unparalleled level of flexibility where  each  workload  can  have  custom  protection  rules.
       Furthermore, time spent livedlocked in kernelspace is minimized.
