We do have some customers, who get charged on a monthly basis for their SAN usage. We already had “reporting” in place, but that wasn’t very flexible. So I went ahead and rewrote the current reporting script from scratch, and this is what I’ve come up with:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 |

I gotta say, once again I learned a lot … two new things about awk!
I know the report itself doesn’t look *that* pretty, but it serves a purpose!
