Hello,
the problem with FQDN is, that getting it often requires a working DNS - if the
DNS or network is down, monit start/reload is then slow as it tries the FQDN
lookup will timeout. If monit is responsible for starting the network interface
and/or DNS, it'll be problem on each start (monit will pause on FQDN lookup
before starting services, making the startup time longer).
There were few issues related to it:
https://bitbucket.org/tildeslash/monit/issues/356/monit-gives-connection-refused-error
https://bitbucket.org/tildeslash/monit/issues/403/the-check-system-unique-name-is-expected
<https://bitbucket.org/tildeslash/monit/issues/403/the-check-system-unique-name-is-expected>
The $HOST now expands to the hostname only and doesn't block - it is possible
to override the hostname using "check system <name>".
Best regards,
Martin
