check_snmp_cisco_memutil.pl

This plugin is found working properly. See below command.
===================================
./check_snmp_cisco_memutil.pl -H 192.168.1.11 -C nishith007 -w 75% -c 95% -f
Status is OK - MEMORY: total: 1348.71 MB, used: 257.94 MB (19%), free: 1090.77 MB | MemTotal=1348.71, MemUsed=257.94, MemFree=1090.77
===================================
Here, "nishith007" is the community name & "192.1681.11" is the ciscp switch ip address.

Works with SNMP v1 & v2 both.

Did what I needed it to with a slight modification for PNP4Nagios support. For whatever reason PNP4Nagios wouldn't graph the data for me straight up, so I modified line 156 to the below instead and it now graphs. The only issue is it doesn't seem to be setting the max right because PNP4Nagios has the top just a little above the actual (IE, instead of showing 300MB as the top, it shows 40MB with 37MB used). Not a big concern right now, probably something I've done wrong, but I'm quite happen with it now.

$temp = sprintf 'MEMORY: total: %.2f MB, used: %.2f MB (%.0f%%), free: %.2f MB | MemUsed=%2$d;%5$d;%6$d;0;%1$d', ( $memtotal / 1000000 ), ( $mem5minused / 1000000 ), $mempcused, ( $mem5minfree / 1000000 ), $warning, $critical;

Plugin itself is good, shows nice data output - for example Status is OK - MEMORY: total: 344.24 MB, used: 46.31 MB (13%), free: 297.93 MB
Only thing that is not good, is that it does not draw graphs.
