Run the following before you clone the vm.
service monit stop
rm -f /var/lib/monit/id
rm -f /var/lib/monit/state
Optional: Run the following once on the new cloned node.
monit -c /etc/monit/monitrc reload

Dear Monit team,
this is a common issue (cloning VMs is an everyday task or maybe you
just have a VM template with an installed monit) and I thought about
how on could solve this annoying problem.
Maybe one could implement a possibility to renew the id file from
M/Monit. And/or one could think about adding an command line option to
monit which does the same:
monit renew-id
Maybe this would be a feature to add in the next release?
Best regards,
Marco

"host_monitid_unique" key
Hi,
the Monit ID is stored in the file (by default ~/.monit.id, you can
customize the location using "set idfile" statement)
To generate new ID:
1.) stop monit on the host with ID duplicate
2.) remove the ID file: rm -f ~/.monit.id
3.) start monit (it will automatically generate new ID and store it to
the file)
Regards,
Martin

Hi All,
I am trying to get multiple instances of same machine started up
in the VMWare VCenter client (Cloned machines from the template of
one using VMWare.
I am able to successfully add server1 and it shows up correctly in
the mmonit screen.
I am getting following error messages in mmonit logs when I try to
add server2
/2013-12-04 05:24:40 SQLException: ERROR: duplicate key value
violates unique constraint "host_monitid_unique"/
/ raised in PostgresqlPreparedStatement_execute at
src/db/postgresql/PostgresqlPreparedStatement.c:184 when
processing URL /collector/
It seems that monit is using something from the system which are
not different in the cloned machines and so I am getting above
errors and the sever2 is not getting added correctly.
My Question is: What does monit use as unique Id ?
Can we manually provide unique ID for monit ? if yes how ?
Regards,
Mital Vora.
