    Very high disk I/O with Zabbix 6.4.3 and MySQL 8.0.32 on FreeBSD 13.2

    Hi all,

    this is my first post here.

    I'm looking for help because I'm running Zabbix 6.4.3 with MySQL 8.0.32 on a virtual machine (on Proxmox) with FreeBSD 13.2.
    The monitoring of my machines is quite simple, just 20-30 assets, with only basic checks (SSH, Ping, HTTP(S)), and no agents running on the machines.

    The problem is that Zabbix+MySQL have a really high disk I/O, something like 1 Mb/s writing stuff on disk, pretty much constantly.

    I honestly don't know how to investigate this problem, any hint would be greatly appreciated.

    Thanks!
Working...
