Monitoring multiple user systemd units

[beeritis]

Hi,

We've got the systemd exporter working and is able to collect user metrics (e.g. any user systemd units).
However - this only is possible to run as one user by either:
a) Run a systemd unit as a specific user , ,set the Environment to XDG_RUNTIME_DIR=/run/user/<uid?>
b) Run a user systemd unit e.g. the service would be started with systemctl --user

Both these approaches work for monitoring systemd services within the user scope.

However - is it possible to monitor multiple user's systemd services without having to set a up a systemd service for each user and on different ports ?

I.e From a very manual perspective, we can see a specific user's systemd state using a command like systemctl --user --machine=<user>@ status --type=service . My example is using root but this can probably be achieved if a dedicated user has the relevant permissions for accessing dbus .

Can the exporter monitor multiple users or does this have to be done user by user and on a different port for each?

Edit , this may be the same as #134 but still would be good to know the feasibility

Thanks,
