Is there a way to debug DNS inside the telegraf snmp plugin?

I have a host with the name `host.name` with the ip `192.168.XX.XX`.

This config works:

```
[[inputs.snmp]]
  agents = ["192.168.XX.XX:161"]

```

This does not:

```
[[inputs.snmp]]
  agents = ["host.name:161"]

```

For other hosts the name work fine and I can do a

```
snmpwalk -v 1 -c public host.name:161 SNMPv2-MIB::sysName.0

```

So my best guess is that DNS resolution fails for some reason inside telegraf, so i would like to see more debug logs for that.
