Description
JOBSTSTS has been very useful to understand what type of IO is coming from application per JOBID/UID and GID, but it also would be nice to have more stats (e.g. like RPC size, discontiguous pages, etc that is covered by "brw_stats" today) into JOBSTATS to understand detail IO workload/size per JOBID.
The other hand, the hybrid system with SSD and HDD (with/without same namespace) is naturally coming and those new stats allow let administrator or users know more guideline/information e.g. which OST devices are preferred by each application.
LU-12872 is used to track the requirement of adding more stats.
LU-16087 is used to track the requirement of show distribution information of jobstats.
