Dear Martin,
Yes there is a file /etc/init.d/monit. So that is the installation file right? So if I need to start after the quit is "monit start" right? How to now make sure that monit itself does not go down in any case ? Is there any mechanism to ensure that safety itself? Thank you.

You can build the rpm directly from monit source code distribution (this rpm installs the /etc/monitrc properly):

rpmbuild -tb monit-5.4.tar.gz

Regarding the chkconfig - yes, your output confirms that monit is set to run in runlevels 3, 4, 5 (default runlevel is usually 3 or 5, you can verify your default runlevel in /etc/inittab).

Monit stop: i suppose the rpm installed monit init script (/etc/init.d/monit) => you can stop monit with "/etc/init.d/monit stop" or via monit CLI: "monit quit".

Dear Martin,
Yes mine is from 3rd party. So where is the right place to pick the right version of monit for centos 6.2? I run chkconfig monit 0:off 1:off 2:on 3:on 4:on 5:on 6:off. So is this fine? What is the command to stop monit I tried monit stop it does not work either? I dont get you how to create the link for the configuration file? Thank you.

If monit was installed via 3rd party package, it's up to the vendor of the package where they install the configuration file, etc. Per your description it seems that the install the configuration file as /etc/monit.conf, but because your monit binary wasn't able to find it and was looking for default monitrc, it seems that they didn't modify the configuration path search. Maybe their init script uses the "-c /etc/monit.conf" option to set the configuration file path. You can verify whether monit is registered to start on boot with "chkconfig" utility. You can keep the rpm package - i'd just suggest to create link for the configuration file (/etc/monit.conf -> /etc/monitrc)

Dear Martin,
Actually I took this monit-5.2-1.el6.rf.x86_64.rpm file from this link http://pkgs.repoforge.org/monit/ and run command rpm -ivh monit-5.2-1.el6.rf.x86_64.rpm for my centos 6.2. So I tried to find monitrc and there is no such file in my system only /etc/monit.conf. So is it ok for me to change the monit.conf to monitrc?After changing and creating the /var/monit. I did this now looks ok.

/etc/init.d/monit start
Starting monit: monit: generated unique Monit id be30cd9f43337901d0f4a48f3ac33712 and stored to '/var/monit/id'
Starting monit daemon with http interface at [localhost:2812]
[ OK ]
Is this the right way to run monit or someother way? What is it init.d is already a registered service? Just to test monit I have down the service which monit is suppose to monitor but there is no alert sent so where to look out next? Thank you

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

Dear All,
I have this file monit.conf in my /etc so I set my mail server and set the receiver.

1. I set the mail server
2. set alert *****
3. I un-comment the the message format
Quote:
set mail-format {
from: address@hidden
subject: monit alert -- $EVENT $SERVICE
message: $EVENT Service $SERVICE
Date: $DATE
Action: $ACTION
Host: $HOST
Description: $DESCRIPTION

Your faithful employee,
Monit
}
Lastly I added this line to check my java process which is ran as a daemon using yajsw.

Quote:
check process commServer with pidfile /var/run/wrapper.commServer8000.pid # check your app pid
if failed port 8000 protocol HTTP
then alert
So thereafter I ran this command
Quote:
/etc/init.d/monit start
Starting monit: monit: Cannot find the control file at ~/.monitrc, /etc/monitrc, /etc/monitrc, /usr/local/etc/monitrc or at ./monitrc
[FAILED]
The I change the monit.conf to monitrc

Quote:
/etc/init.d/monit start
Starting monit: monit: Error opening the idfile '/var/monit/id' -- No such file or directory
Starting monit daemon with http interface at [localhost:2812]
[ OK ]
Then lastly I run this to check if monit running but nothing either too. So where could be my mistake?

Quote:
/etc/init.d/monit start
Starting monit: monit: Error opening the idfile '/var/monit/id' -- No such file or directory
Starting monit daemon with http interface at [localhost:2812]
[ OK ]
