Hello, i have installed Elasticsearch, Kibana and Fluentd on Debian 7.0
with rsyslog for Logging Network devices like Switches and Firewalls. I get
from the Firewall the hostname and see it in Kibana but from the Switches
get I only the IP Address. We don't want to have the Switches on the DNS
Server but i have written the Hostnames and the IP Adresses from the
Switches in etc/hosts on the Debian Server.
But the resolution did not go.
What can i do?
Best Regards
Daniel

You'll have to add it to DNS.
I think the hosts file can be used like that, but it'd depend on the
application reading it to do the translation.

It's not a specific ES question, you should ask your network administrator
for assistance.
If your firewall can provide the hostname (or better, the DHCP daemon of
your firewall/router?) you should be able to configure your hosts to
receive the DHCP host name at boot time.
