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