This is because the current perl based pattern matching will not match the results on the *-disk-space file based on the leading hostname.
On pt-stalk:
556 local used_bytes=$(perl -ane 'm!^/! && print $F[2] * 1024' "$file")
557 local free_bytes=$(perl -ane 'm!^/! && print $F[3] * 1024' "$file")
558 local pct_used=$(perl -ane 'm!^/! && print ($F[4] =~ m/(\d+)/)' "$file")
559 local pct_free=$((100 - $pct_used))
Sample disk-space:
[root@util01 percona]# cat /mnt/stor01/revin/2012_10_26_23_27_25-disk-space
Filesystem 1024-blocks Used Available Capacity Mounted on
xx.xxx.xxx.xxx:/ 1918433376 1052659424 768323200 58% /mnt/stor01
Maybe something like this could work since the contents of disk-space is deterministic, though Im not sure if this will work in all cases.
