From: Xiubo Li <xiubli@xxxxxxxxxx> This series is based the previous patches of the metrics in kceph[1] and mds daemons record and forward client side metrics to manager[2][3]. This will send the caps/read/write/metadata metrics to any available MDS only once per second as default, which will be the same as the userland client, or every metric_send_interval seconds, which is a module parameter, the valid values for metric_send_interval will be 0~5 seconds, 0 means disabled. And will also send the metric flags to MDS, currently it supports the cap, read latency, write latency and metadata latency. Also have pushed this series to github [4].
