Monitor ZFS shrink events

Question

I am using ZFS with Proxmox (debian based). The system has enough free RAM but I am close to hitting the point where ARC shrinking could be trigered. I would like to monitor these events, or at least have a log where I can see how many times a shrink event has been triggered by ZFS.

Why do want to monitor for ZFS ARC shrink events? Are you seeing performance issues correlated with them? — Andrew Henle, Feb 27 '21 at 14:07

You would probably want to monitor /proc/spl/kstat/zfs/arcstats. size should decrease in case of ARC shrinking. AFAIK there is no build in event logging about ARC shrinking. For more info about arcstats, check out this post.
