You could use NCPA. With check_ncpa.py, you could specify the units you would like to use.

-u UNITS, --units=UNITS
The unit prefix (k, Ki, M, Mi, G, Gi, T, Ti) for b and
B unit types which calculates the value returned.

Example:

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H x.x.x.x -t 'mytoken' -P 5693 -M memory/virtual -u Gi -w 50 -c 80
OK: Used memory was 35.70 % (Available: 20.52 GiB, Total: 31.90 GiB, Free: 20.52 GiB, Used: 11.38 GiB) | 'available'=20.52GiB;16;26; 'total'=31.90GiB;16;26; 'free'=20.52GiB;16;26; 'used'=11.38GiB;16;26;
