snmp plugins

[Nelson Serafica]

is it possible to monitor disk usage, load and mem using nagios with only snmp running in remote server?
  
  i have no root access to remote server (only in local server) but there  was snmp running in remote with community public. i have installed snmp  in local and download check_snmp_mem.pl in sourceforge but when i run  it manually it shows:
  
  perl check_snmp_mem.pl and ./check_snmp_mem.pl
  
  Can't locate Net/SNMP.pm in @INC (@INC contains:  /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi  /usr/lib/perl5/site_perl/5.8.7/i386-linux-thread-multi  /usr/lib/perl5/site_perl/5.8.6/i386-linux-thread-multi  /usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi  /usr/lib/perl5/site_perl/5.8.4/i386-linux-thread-multi  /usr/lib/perl5/site_perl/5.8.3/i386-linux-thread-multi  /usr/lib/perl5/site_perl/5
  
  Attache is the script of check_snmp_mem.pl
