Ah, you were reading top's output.
Then I gather the proc's resident set size is meant,
roughly what the proc used from physical memory.
For that to get you could run a ps command.
Do we know the proc's PID beforehand (maybe from some pid file),
or do we need to parse the proc table first?
Assumed we knew the PID you could run
Code:
$ ps -p <PID> -o rss=

Depends on the ps/OS; on Linux this number should be in KB.
Other ps return number of memory pages.
If you want to check it on a regular basis
you could set up a cronjob which checks every 5 mins or so.
Even better yet would be a monitoring solution like Nagios
(but maybe overkill?)
From the Nagios Plugins you could set up a check command
involving the check_procs plugin.

systemd-rc-local-generator

SYSTEMD-RC-LOCAL-GENERATOR(8)				    systemd-rc-local-generator				     SYSTEMD-RC-LOCAL-GENERATOR(8)

NAME

       systemd-rc-local-generator - Compatibility generator for starting /etc/rc.local and /usr/sbin/halt.local during boot and shutdown

SYNOPSIS

       /lib/systemd/system-generators/systemd-rc-local-generator

DESCRIPTION

       systemd-rc-local-generator is a generator that checks whether /etc/rc.local exists and is executable, and if it is pulls the
       rc-local.service unit into the boot process. This unit is responsible for running this script during late boot. Note that the script will
       be run with slightly different semantics than the original System V version, which was run "last" in the boot process, which is a concept
       that does not translate to systemd. The script is run after network.target, but in parallel with most other regular system services.

       systemd-rc-local-generator also checks whether /usr/sbin/halt.local exists and is executable, and if it is pulls the halt-local.service
       unit into the shutdown process. This unit is responsible for running this script during later shutdown.

       Support for both /etc/rc.local and /usr/sbin/halt.local is provided for compatibility with specific System V systems only. However, it is
       strongly recommended to avoid making use of these scripts today, and instead provide proper unit files with appropriate dependencies for
       any scripts to run during the boot or shutdown processes.

       systemd-rc-local-generator implements systemd.generator(7).
