Put the calculation of the memory into a function too. Call it only when needed - currently you call it all the time, makes no sense. It will be executed no matter what happens in the case/esac-block.
Second thing is, if you iterate through arguments with $# -gt 0 it will always be the same. You miss the shift.
Third, have the exit 0 at the very end of the script since this is, if not aborted earlier, the good exit code you want to have.

nagios::plugin::config
Nagios::Plugin::Config(3pm) User Contributed Perl Documentation Nagios::Plugin::Config(3pm)
NAME
Nagios::Plugin::Config - read nagios plugin .ini style config files
SYNOPSIS
# Read given nagios plugin config file
$Config = Nagios::Plugin::Config->read( '/etc/nagios/plugins.ini' );
# Search for and read default nagios plugin config file
$Config = Nagios::Plugin::Config->read();
# Access sections and properties (returns scalars or arrayrefs)
$rootproperty = $Config->{_}->{rootproperty};
$one = $Config->{section}->{one};
$Foo = $Config->{section}->{Foo};
DESCRIPTION
Nagios::Plugin::Config is a subclass of the excellent Config::Tiny, with the following changes:
o Repeated keys are allowed within sections, returning lists instead of scalars
o Write functionality has been removed i.e. access is read only
o Nagios::Plugin::Config searches for a default nagios plugins file if no explicit filename is given to "read()". The current standard
locations checked are:
/etc/nagios/plugins.ini
/usr/local/nagios/etc/plugins.ini
/usr/local/etc/nagios /etc/opt/nagios/plugins.ini
/etc/nagios-plugins.ini
/usr/local/etc/nagios-plugins.ini
/etc/opt/nagios-plugins.ini
To use a custom location, set a "NAGIOS_CONFIG_PATH" environment variable to the set of directories that should be checked. The first
"plugins.ini" or "nagios-plugins.ini" file found will be used.
