output of 'ceph df' seems to be changed in mimic-Release

[hihiuztrewq]

I had to change two lines in the check_ceph_df script after upgrading my ceph cluster to mimic:

Line 140 & 141:

<            global_usage_percent = float(globalvals[3])
<            global_available_space = globalvals[1]
>            global_usage_percent = float(globalvals[6])
>            global_available_space = globalvals[2]

Can you please give me a example output of ceph df ?

no problem:

user@server1:~$ ceph df

Ok I see the problem, here is the output for Ceph Luminous:

$ ceph --version

There is no space between the value and unit (e.g. 152G)

To fix this, we should use the json output:

tschopp@controller:~$ ceph df -f json|jq .
