Frequently Asked Questions

Q: Telegraf cannot resolve hostnames that are resolvable via dig, host, nslookup, etc.

Go uses a pure Go resolver by default for 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
