### Q: Telegraf cannot resolve hostnames that are resolvable via `dig`, `host`, `nslookup`, etc.
|
||
|
|
|
||
|
|
Go uses a pure Go resolver by default for [name resolution](https://golang.org/pkg/net/#hdr-Name_Resolution).
|
||
|
|
This resolver behaves differently than the C library functions but is more
|
||
|
|
efficient when used with the Go runtime.
|
||
|
|
|
||
|
|
If you encounter problems or want to use more advanced name resolution methods
|
||
|
|
that are unsupported by the pure Go resolver, you can switch to the cgo
|
||
|
|
resolver.
|
||
|
|
|
||
|
|
If running manually set:
|
||
|
|
```
|
||
|
|
export GODEBUG=netdns=cgo
|
||
|
|
```
|
||
|
|
|
||
|
|
If running as a service add the environment variable to `/etc/default/telegraf`:
|
||
|
|
```
|
||
|
|
GODEBUG=netdns=cgo
|
||
|
|
```
