=head1 NAME

fusion_ a Plugin for displaying VMWare Fusion Stats

=head1 INTERPRETATION

This plugin displays the following charts:

1) pcpu
2) pmem
3) mem

You can set the modes with naming the softlink:

1) fusion_pcpu
2) fusion_pmem
3) fusion_mem

This Plugin uses ps for gaining the data:

> ps -A -c -o pcpu,pmem,rss=,comm,args -r | grep vmware-vmx
5,0 19,5   3271768 innoq-winxp.vmx 		vmware-vmx
4,6 10,7   1801768 Gateway.vmx           vmware-vmx
2,3  5,8   976288 Jenkins.vmx            vmware-vmx
2,0 22,6   3784144 Mac_OS_X_10.9.vmx     vmware-vmx
0,0  0,0   620 grep vmware-vmx           grep

So the Output should be pretty standard about all MacOS/Fusion Versions.

=head1 CONFIGURATION

No Configuration necessary!

TODO:
still a bug with getting pcpu,pmem,rss=,comm as an output, have filter it with if( $vm[3] =~ /(?<!comm)$/)
