Hi,
the default monit configuration file name is "monitrc", not "monit.conf" (that
is used by some 3rd party packages which modify the source code to find the
monit.conf instead of monitrc).
The idfile error is repotted most probably because your configuration file
contains "set idfile /var/monit/id" statement, but the directory "/var/monit/"
most probably doesnt exist => the unique id cannot be saved to the given
location. The id is used when Monit is configured with M/Monit to pair the host
entry in M/Monit with messages from Monit (pairing by source IP address won't
be reliable, as the monit agents can be behind firewall with IP masquerading,
so all the agents would update one host entry and you'll sporadically see
services of different hosts under the same entry, hence the concept of
per-instance ID).
To fix the idfile error:
mkdir /var/monit
+ set the permissions on that directory to allow the user under which monit is
running to write to this directory.
Regards,
Martin
