please either add the -I option as noted in previous mail which will show output in console or get the details from /var/log/monit.log.

It would seem to me that if you changed nothing at all, and it just stopped working, that some issue exist other than monit itself, like data or memory corruption of some sort.

What if you change the port assigned to just see if it can read?

Thank you,

Sergio,

Even if i enable the http server, it doesn't work:

set httpd port 2812 and
     use address localhost
     allow localhost
     allow admin:monit
#   allow @monit
#    allow @users readonly

Look at the log:

[BRST Oct 21 09:16:53] info     : Starting monit daemon with http interface at [localhost:2812]
[BRST Oct 21 09:16:53] info     : Starting monit HTTP server at [localhost:2812]
[BRST Oct 21 09:16:53] info     : monit HTTP server started
[BRST Oct 21 09:16:53] info     : Monit started
[BRST Oct 21 09:16:53] error    : monit: unable to read data from the file

When i tried to enable the lines allow @monit and allow @users readonly, i got this error when i start it:

ldap1:/etc# /etc/init.d/monit syntax
/etc/monit/monitrc:96: Error: syntax error '@'

I also have checked my firewall and all doors are open.

Monit use internal http server to read data.
If you not configure http monit server, you obtain this error....

You put this in /etc/monit.conf

Hi Sergio,

I have made the change as you show below and now i'm getting this:

ldap1:/etc/monit# /etc/init.d/monit syntax
/etc/monit/monitrc:96: Error: syntax error '@'

I think my problem isn't with "set httpd" option, because i have put it off, and i still getting the same error message:

BRST Oct 21 09:02:14] info     : Starting monit daemon
[BRST Oct 21 09:02:14] info     : Monit started
[BRST Oct 21 09:02:14] error    : monit: unable to read data from the file

Add this in your monit.conf

Dear Sirs,

We have been using monit for a long time and everthing was working well, but today when we get into our server, we saw that monit was stopped.

We did not make any changes, it was working fine and simply stopped.

We have checked the file syntax:

ldap1:/var/run# /etc/init.d/monit syntax
Control file syntax OK

We have checked permissions, disk space and everthing is ok too.

This is what we get back from the log file:

[BRST Oct 21 08:35:38] info     : Starting monit daemon with http interface at [*:2812]
[BRST Oct 21 08:35:38] info     : Starting monit HTTP server at [*:2812]
[BRST Oct 21 08:35:38] info     : monit HTTP server started
[BRST Oct 21 08:35:38] info     : Monit started
[BRST Oct 21 08:35:39] error    : monit: unable to read data from the file

So after that error monit: unable to read data from the file, it doesn't start.

Have someone knows something about this error? We have decided to report to the general list, because we made a lot of searchs at Google and didn't find nothing.

Regards,
