LVM cache monitoring Details in kernel documentation https://www.kernel.org/doc/Documentation/device-mapper/cache.txt
allows you to evaluate the efficiency of caching by the built-in dm-cache mechanism.

into your Zabbix server (click on the Raw
button to download)This script assumes that you have ONLY ONE caching device and polls the first device. Therefore, it does not require configuration and specifying a device name. Working with disks implies elevated privileges and therefore you need do not forget about sudoers_zabbix_lvmcache file.
