* `memory_page_cache_used`: Page cache memory usage, in Bytes. Memory usage state is reported under the `state` metric label (e.g. `active`, `inactive`). `active` means the memory has been used more recently and usually not reclaimed until needed. Summing values of all states yields the total page cache memory used.
* `memory_unevictable_used`: [Unevictable memory][/proc doc] usage, in Bytes.
* `memory_dirty_used`: Dirty pages usage, in Bytes. Memory usage state is reported under the `state` metric label (e.g. `dirty`, `writeback`). `dirty` means the memory is waiting to be written back to disk, and `writeback` means the memory is actively being written back to disk.
### OS features
The guest OS features such as KTD kernel, GPU support are collected. Below are the OS
features collected:
* `KTD`: Enabled, if KTD feature is enabled on OS
* `UnifiedCgroupHierarchy`: Enabled, if Unified hierarchy is enabled on OS.
* `KernelModuleIntegrity`: Enabled, if load pin security is enabled and modules are signed.
* `GPUSupport`: Enabled, if OS has GPU drivers installed like nvidia.
* `UnknownModules`: Enabled, if the OS has third party kernel modules installed.
UnknownModules are derived from the /proc/modules compared with the known-modules.json.
And an option:
`knownModulesConfigPath`: The path to the file that contains the known modules(default
modules) can be set. By default, the path is set to `known-modules.json`
