Hi,
I have been studying the document from Ceph and Rados but I could not find any metrics to measure the number of read/write operations for each file. I understand that Cephfs is the front-end, the file is going to be stored as an object in the OSD and I have found that Ceph provides a Cache Tiering feature which also requires the monitor for read/write operation for each object. Could someone please give me guidance on how this is achieved? Thanks.
You can try to get the "perf dump" from ceph-fuse to measure. The osd write/reads are not fine-grained though. -- Patrick Donnelly, Ph.D. He / Him / His Red Hat Partner Engineer IBM, Inc. GPG: 19F28A586F808C2402351B93C3301A3E258DD79D
