Checks the ram usage on the local machine, good for remote checks using nrpe. Works on 32-bit and 64-bit Linux systems.
Just run it. The help displays all the necessary details, it follows the standards of all the other nagios plugins.

I have made some chalges on lines between lines 68-88 to add PerfData :

if percent == True:
percentage_free = int( float(total_free) / float(memtotal) * 100 )
if percentage_free _threshold)
return CRITICAL
elif percentage_free %d MB used)|percent_free_ram=%d;%d;%d" % (percentage_free,total_used_megs,memtotal_megs,percentage_free,warning_threshold,critical_threshold)
return WARNING
else:
print "RAM OK: %d%% ram free|percent_free_ram=%d;%d;%d" % (percentage_free,percentage_free,warning_threshold,critical_threshold)
return OK
else:
if total_free return WARNING
else:
print "RAM OK: %dMB ram free|free_ram=%d;" % (total_free_megs,total_free_megs)
return OK
