On Linux, these metrics depend on `/procfs`, `/sysfs`, systemd, or custom files, and the actual values of metrics will be read from `/proc`, `/sys`, or systemd as needed: `cpu`, `cpufreq`, `meminfo`, `diskstats`, `filesystem`, `stat`, `loadavg`, `vmstat`, `netdev`, `netstat`, `sockstat`, `filefd`, `nvme`, and `processes` depend on `procfs`. `cpufreq`, `hwmon`, `thermal_zone`, and `powersupplyclass` depend on `sysfs`. `systemd` depends on systemd services. `textfile` requires explicit path configuration using `collector.textfile.path`.

Collectors marked `Unreleased` aren't present in any released version yet, and enabling them has no effect. The `timex` collector is tracked in [`fluent-bit#11718`](https://github.com/fluent/fluent-bit/pull/11718).
