What it sounds like — the pgmap includes the aggregate number of read/write/whatever ops done across the cluster which are reported in its time period, and will derive an average from that to output. This is distinctly not a precise dynamic assessment, though — think of it as being an approximate activity gauge, not something you can query dynamically for instantaneous stats. -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
