Unit file counts for a scope (root or user), broken down by unit type.

UnitFilesStats

Unit file statistics collected from the filesystem for root and user scopes.

UnitStates

Functions

collect_unit_files_stats

Collect unit file statistics from the filesystem. fs_root is prepended to all paths — empty string for the host, /proc/<pid>/root for containers.

parse_state

Parse state of a unit into our unit_states hash.

parse_unit_state

Pull all units from dbus and count how system is setup and behaving

update_unit_stats

Async wrapper that can update unit stats when passed a locked struct. fs_root is prepended to filesystem paths for unit file stats — empty string for the host, /proc/<pid>/root for containers.
