Is there an easy way to poll the ceph cluster buckets in a way to see how much
space is remaining? And is it possible to see how much ceph cluster space is
remaining overall? I am trying to extract the data from our Ceph cluster and
put it into a format that our SolarWinds can understand in whole number
integers, so we can monitor bucket allocated space and overall cluster space in
the cluster as a whole.
Via Canonical support, the said I can do something like "sudo ceph df -f
json-pretty" to pull the information, but what is it I need to look at from the
output (see below) to display over to SolarWinds?

}
},
And a couple of data pools...
