Obtain zpool performance information for cache

edited Aug 8, 2018 5:00AM in Oracle Solaris ZFS File System (MOSC) 1 commentAnswered

Hi,

Solaris 11.3 SPARC.

SRU: Oracle Solaris 11.3.28.4.0
Two non-global zones, no CPU or memory restrictions.

rpool - 2x600GB SATA disks.

dpool - 6x1.6TB NVMe drives.

I've utilised dtrace scripts, zilstat, kstat, mdb, zpool iostat -v and a couple of others.

I'm trying to find a script that provides the following output on the dpool zpool.

Read cache size

Read cache hit ratio %

Read cache bandwidth MB/sec

Read cache operations IOPS

Write cache size

Write cache hit ratio %

Write cache bandwidth MB/sec

Write cache operations IOPS

I'm thinking that someone has performed these outputs before in a script utilising the scripts and built-in functions and would hopefully save me the time to write my own.

Howdy, Stranger!
