[LU-10698] Specify complex JobIDs for Lustre

• Type: Improvement
• Resolution: Fixed
• Priority: Major
• Fix Version/s: Lustre 2.12.0
• Assignee: Jinshan Xiong
• Reporter: Jinshan Xiong

Description

One thing that Lustre has been missing for a long time is I/O profiling. Lustre does support I/O profiling per process and per client, but it doesn't support profiling I/O per job, which is the commonly used case in reality.

It would be desirable to add I/O profiling to client, llite in particular, by JOBID, also it will be better to provide tools to accumulate those stats from multiple clients and plot them correspondingly.
