mmonit / monit upgraded to latest version -> host appear as localhost

[Ben Soot]

Hi all,

Today I upgraded my monit and mmonit installations:

(on host bar.com only) monit 5.4 -> monit 5.13
mmonit-3.1.2 -> mmonit-3.5

i used the upgrade script as described here: 
https://mmonit.com/wiki/MMonit/Release3-5

All the monitors seem to work fine, however the host bar.com, that i 
upgraded, shows as "localhost" in mmonit Status view 
(https://foo.com/status/hosts/).
The other hosts show correctly with their fqn.
Before the mmonit upgrade (with and without the monit upgrade of host 
bar.com) the hostname of appeared correctly as bar.com

If have the fqn set in /etc/hosts as well as in /bin/hostname

Any ideas?

Thanks a lot, Ben
