Have DNS names instead of IPs in dashboard

Hi There,
first thanks for the nice solution I'm evaluating right now.
Is there a way to show DNS names instead of the IPs in the dashboard?
DNS is working properly on the machine.
Best regards
David

You will be interested in the DNS filter:
http://logstash.net/docs/1.4.2/filters/dns
When you enable the above filter and logs come in, Nagios Log Server will attempt to resolve the IPs to names via reverse DNS lookup. NLS can then re-write specified fields with FQDN instead of an IP.
You will likely want to define a filter similar to the following:
Code: Select all
dns {
reverse => [ "host" ]
action => [ "replace" ]
add_tag => [ "dns" ]
}

Thanks for the hint.
I also just figured out there's a field called Hostname
