Are you running node_exporter in Docker?

no, on VM

What did you do that produced an error?

Perhaps this is not a mistake.
In the old version (0.15.2) I saw metrics like:
node_systemd_unit_state{name="var.mount",state="activating"} 0
node_systemd_unit_state{name="var.mount",state="active"} 1
node_systemd_unit_state{name="var.mount",state="deactivating"} 0
node_systemd_unit_state{name="var.mount",state="failed"} 0
node_systemd_unit_state{name="var.mount",state="inactive"} 0
They help me monitor network-share mounts state
But in new versions > 0.18+
There are no such metrics in the new version and i dont understand how to enable them.
node-exporter with systemd collector only shows metrics .service .socket .target

What did you expect to see?

metrics with type=mount like:
node_systemd_unit_state{name="var.mount",state="activating"} 0
node_systemd_unit_state{name="var.mount",state="active"} 1
node_systemd_unit_state{name="var.mount",state="deactivating"} 0
node_systemd_unit_state{name="var.mount",state="failed"} 0
node_systemd_unit_state{name="var.mount",state="inactive"} 0

What did you see instead?

nothing

I found the reason. It turns out that by default the mount and auto-mount are present in the blacklist by default and in order to pull them out, you need to redefine the blacklist manually.
something like that:
ExecStart=/opt/node_exporter/node_exporter --collector.systemd
--collector.systemd.unit-whitelist=.*
--collector.systemd.unit-blacklist=.+.(automount|device|service|target|scope|slice)
--collector.filesystem.ignored-mount-points=^/(sys|proc|dev|run)($|/)
