Harvest+Grafana: generates high rate of Read IOPS on the storage



    We use NetApp volume as underlying storage for Harvest+Grafana setup. I recently noticed that that volume constantly runs at ~3K Read IOPS and ~350 Write IOPS.

    The process generating all these IOPS seems to be (iotop seems to confirm that - it shows much more reads than writes for that process).

    Is this normal/expected for carbon-cache to generate such high ammount of read IO?
