[lustre-discuss] [EXTERNAL] [BULK] IOPS monitoring

Mon Apr 13 10:31:06 PDT 2026

The llstat executable that is part of lustre is my go-to.  Running "llstat -i 1 mdt” on and MDS will give you a pretty good feel for what’s happening on at given MDS.  It’s useful to part these and send to a graphana instance for history and graphing.

Hello all,

What’s the best way to monitor Lustre IOPS? I can’t seem to find an up-to-date solution.

Sincerely,
