Modification and fix of check_netapp command


#1

Below is the diff of the check-netapp that corrects the negative numbers with volumes over 2TB and which converts output to GB for readability. The complete text can be found at iisc.com/check_netapp . The original check_netapp is by Ken Mckinlay with additional Nagios compatibility work by Ken Nerhood. My change is a relatively minor incremental one.

The result of the change can be seen in this output:
OLD/check_netapp -H x.x.x.x -C public -v DISKUSED -o /vol/vol_bpdimage/ -w 80 -c 90
DISKUSED OK - /vol/vol_bpdimage/ - total: 1090519040 Kb - used 589970728 Kb (54%) - free: 500548312 Kb|NetApp /vol/vol_bpdimage/ Used Space=589970728KB;872415232;981467136;0;1090519040

libexec/check_netapp -H x.x.x.x -C public -v DISKUSED -o /vol/vol_bpdimage/ -w 80 -c 90
DISKUSED OK - /vol/vol_bpdimage/ - total: 1040 Gb - used 562 Gb (54%) - free: 477 Gb|NetApp /vol/vol_bpdimage/ Used Space=562GB;832;936;0;1040

Note: I am calculating real GB using 1024*1024. If you want manufacturer’s GB then change the ‘1048576’ to ‘1000000’ in the diff below.
