We need to consider a solution for getting the low-level or OS-specific platform properties required for introspection. Ideally, we should add a simple interface for getting this information as it will be platform-specific in any case:

ProcessInfo¶

• PID
• Program name (On POSIX systems, argv⁰)
• Command line arguments (On POSIX systems, does not include argv⁰, i.e. argv[1:])
• Start time of the process encoded as a timestamp in UTC in microseconds since UNIX epoch.

HostInfo¶

• HostID
• Hostname

Linux strategy for HostID:

     * * contents of /etc/machine-id (excluding whitespace characters)
     * * contents of /var/lib/dbus/machine-id (excluding whitespace
     *   characters)
     * * Return value of POSIX gethostid function in hexadecimal base
     * * Hostname

ProcessInfo and HostInfo should be realized as singletons as the information should only be collected once during factory initialization. The singleton may also instantiate the platform-specific implementation classes of these interfaces.
