My munin runs on rbd in a vm. It has a rrdcached with options: ''rrdcached -w 1800 -z 600''. It uses 1.5G as cache for writing to 60000 rrds updated every 5 minutes. This creates a permanent Throughput of 1.2 MB/s with 80 Disk-IO/s in a 5 min avg. A peak usage for Disk-IO/s is 1000IO/s on a 14 OSD-Node Cluster.
