Logfile / add path as label

Hi,
how can I add the full path + filename of a logfile from loki.source.file as a label?
I tested with relabel, see below, but there is no label filename.

loki.source.file "logs_integrations_test" {
	targets    = local.file_match.logs_integrations_test.targets
	forward_to = [loki.relabel.logs_integrations_test.receiver]
}

loki.relabel "logs_integrations_test" {
	forward_to = [loki.write.grafana_cloud_loki.receiver]

	rule {
		source_labels = ["__path__"]
		target_label  = "filename"
	}
}

Try sending it directly to loki.process or loki.write. I am pretty sure filename is set for you if you use loki.source.file without you having to do anything special.

You are right, thank you
