Please explain exactly what you're doing when you say "unable to return".
If you're going to the Prometheus web interface (usually at x.x.x.x:9090)
and entering "ifName" as the query and hitting Enter, and getting no
results, then it seems like you're not successfully scraping the if_mib
from any targets. However if you're getting some other metrics like
ifHCInOctets from the if_mib, then maybe the way you built snmp.yml from
generator.yml is broken.
You'll need to work out what's happening. In the same Prometheus web
interface go to Status > Targets as a starting point. If it says the target
is "up" then try doing exactly the same scrape manually:
curl -v 'x.x.x.x:9116/snmp?target=y.y.y.y&module=zzzz&auth=aaaa'
and/or point a web browser at x.x.x.x:9116/snmp/status as I suggested
before. Also look at snmp_exporter's stdout ("systemctl status
snmp_exporter" if you're running it under systemd).
Basically, you need to divide and conquer. If ifName not being returned
from any targets, then is it a problem with your snmp.yml, or with your
prometheus scrape config, or something else? You haven't shown your scrape
config, so the problem could be there. You also haven't shown the snmp.yml
which came from your generator.yml.
