## Some features
- Sending the SIGTERM signal is default corrective action. If the victim does not respond to SIGTERM, with a further drop in the level of memory it gets SIGKILL.
- Impact on the badness of processes via matching their
- names,
- cgroup_v1,
- cgroup_v2,
- realpathes,
- environs,
- cmdlines and
- euids
with specified regular expressions
- If the name or cgroup_v1 of the victim matches a certain regex pattern, you can run any command instead of sending the SIGTERM signal (the default corrective action) to the victim. For example:
- Customizing victim selection: impact on the badness of processes via matching their names, cgroup_v1, cgroup_v2, exe realpathes, environs, cmdlines and euids with specified regular expressions
- Customizing corrective actions: if the name or cgroup_v1 of the victim matches a certain regex pattern, you can run any command instead of sending the SIGTERM signal (the default corrective action) to the victim. For example:
- `sysmemctl restart foo`
- `kill -INT $PID` (you can override the signal sent to the victim, $PID will be replaced by the victim's PID)
- `kill -TERM $PID && script.sh` (in addition to sending any signal, you can run a specified script)
