Change Name in Stack Monitoring

[tomx1]

By default, beats which are sending monitoring data to a dedicated monitoring cluster (by setting 'monitoring.elasticsearch.monitoring.enabled: true') are showing up in Kibana Stack Monitoring with their hostname without FQDN.
I want that they show up with their full hostname as reported by linux command 'hostname -f', tried a few things without success, any hints how to achive this?

still looking for a solution

Did you restart the beat after changing the local hostname?

[tomx1]

I have not changed the hostname, why should I? The information is already here, I just want that my hosts are showing up as "hostname.example.com" instead of just "hostname"

This is an example for a correct debian hostname config. Packetbeat should give a way to use short or full name:

user@hostname:~$ hostname
hostname
user@hostname:~$
user@hostname:~$ hostname -f
hostname.example.com
user@hostname:~$
user@hostname:~$ cat /etc/hosts
127.0.0.1       localhost
127.0.1.1       hostname.example.com  hostname

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
user@hostname:~$
user@hostname:~$
user@hostname:~$ cat /etc/hostname
hostname
user@hostname:~$

libbeat uses os.Hostname() internally to get the name if one is not specified in the config. IIRC you can specify another name with the name attribute
