memory check linux appliance

Project Notes
This script was written to monitor a linux appliance residing on an external network where the nagios server did not have direct access. the only gateway to the host was a windows server. It does not require access to utils.pm from nagios plugins. It does not require any snmp utilies like snmpget or linux utilities like free. you need to have install from cpan the following modules: Net::SNMP Nagios::PLugin Math::Round it attempts to calculate the real used memory on a linux using UCD-SNMP-MIB. it will return the total used percent and includes the buffer and cache in the calculations just like explained in www.linuxatemyram.com. This is my first script...bear in mind the bugs and unorthodox coding. usage: just drop it to a your windows plugin folder ond either configure nsclient.ini to be accessed via nrpe. it can of course also run from a nagios server. just configure the snmp v1/2 community and the warning and critical threshold.
