          This collector monitors DMCache, providing insights into capacity usage, efficiency, and activity.
          It relies on the [`dmsetup`](https://man7.org/linux/man-pages/man8/dmsetup.8.html) CLI tool but avoids directly executing the binary.
          Instead, it utilizes `ndsudo`, a Netdata helper specifically designed to run privileged commands securely within the Netdata environment.
          This approach eliminates the need to use `sudo`, improving security and potentially simplifying permission management.
