Hi Robert, I've just been testing your ceph check and I have made a small modification to allow it to adjust itself to suit the autoscaling of the units Ceph outputs. Here is the relevant section I have modified:- if line[1] == 'TB': used = saveint(line[0]) * 1099511627776 elif line[1] == 'GB': used = saveint(line[0]) * 1073741824 elif line[1] == 'MB': used = saveint(line[0]) * 1048576 if line[7] == 'TB': size = saveint(line[6]) * 1099511627776 elif line[7] == 'GB': size = saveint(line[6]) * 1073741824 elif line[7] == 'MB': size = saveint(line[6]) * 1048576 I'm guessing that it may also need a PB part as well but I can only dream of having a cluster large enough to test this. I have also noticed that the graphs generated in Check_MK scale in base 10, so the graphs will always be slightly out compared to the true value. I don't know if there is a way to change this, I couldn't see anything from the brief look I had. I may also look at putting some cluster IO perf data and # of objects in the future, will keep you posted.

It shows used "GB". Are these GiB (Gibibyte, 2^30 bytes) oder SI GB (Gigabyte, 10^9 bytes)?
