Subject: [PATCH v10 0/6] ceph: add perf metrics support
Date: Wed, 18 Mar 2020 10:05:50 -0400 [thread overview]
Message-ID: <1584540356-5885-1-git-send-email-xiubli@redhat.com> (raw)
From: Xiubo Li <xiubli@redhat.com>
Changed in V10:
- rebase to the latest testing branch
- merge all the metric related patches into one
- [1/6] move metric helpers into a new file metric.c
- [2/6] move metric helpers into metric.c
- [3/6] merge the read/write patches into a signal patch and move metric helpers to metric.c
- [4/6] move metric helpers to metric.c
- [5/6] min/max latency support
- [6/6] standard deviation support
Changed in V9:
- add an r_ended field to the mds request struct and use that to calculate the metric
- fix some commit comments
