The problem is that the filename must end with ".prom", i.e. you need to
create "apt1.prom" not "apt1-prom"
Also, you need to enable the functionality with a flag to node_exporter:
node_exporter --collector.textfile.directory=/var/lib/node_exporter
See the documentation
here: https://github.com/prometheus/node_exporter#textfile-collector
