- This integration requires read access to `/proc/slabinfo`, which is accessible only to the root user by
- default. Netdata uses Linux Capabilities to give the plugin access to this file. `CAP_DAC_READ_SEARCH`
- is added automatically during installation. This capability allows bypassing file read permission checks
- and directory read and execute permission checks. If file capabilities are not usable, then the plugin is
- instead installed with the SUID bit set in permissions sVko that it runs as root.

- Due to the large number of metrics generated by this integration, it is disabled by default and must be
