It appears the new version 5.1.1 has a bit of a different structure than explainewd here.
I get some errors with my configuration like mo repeated to fast disabling for 5 minutes, and an unmonitor error.

It does however, appear to be functioning, as I can watch what users login, in real time, and various SPI activity. However, I don;t know if it is monitoring the service properly to restart it, when needed.

Searched the net for days until I’ve found this thread and understand I must replace the localhost with the server’s IP for Apache monitoring to work… but, better late then never :)
Thanks for the intel!

@ Mohd. Anas –> VSFTP can’t be monitored using MONIT. Reason is as what you already know… it doesn’t create PID file ;)
And MONIT uses PID file to learn about running process…. :)

@ Vivek –> I am a big NixCraft fan. Sorry to advice you but please update the document for monitoring and managing services from a web interface.

# vi /etc/monitrc
set httpd port 2812 # To bind monit on port 2812 of apache
allow admin:monit # require user ‘admin’ with password ‘monit’

Restart monit to apply changes then open http://:2812 in web-browser.

Hello
first of all thanks for great manual. THe problem is, that i did as i descrbed here, everything was ok … until this

Now start monit: # init -qOR # telinit -q

Goting such output
[root@server etc]# init -q init: invalid option -- q Usage: init 0123456SsQqAaBbCcUu [root@server etc]# telinit -q telinit: invalid option -- q Usage: telinit 0123456SsQqAaBbCcUu

and of course all steps after this

f.e. for this command

# tail -f /var/log/messages
server stop for a minute, … i stop it manually …
later check that my messages file become ~16mb

so, for now Monit don’t monitor, don’t send any alert … and don’t know what to do ?

try to find any solution, or may be unistall it

Hi,

I am a newbie and am having problems getting monit to work. I have gotten all the way to the following command but I get stuck after this:

mo:2345:respawn:/usr/local/bin/monit -Ic /etc/monitrc

I inserted this command into the inittab file but after that I can not simply copy and paste “init -q” into the shell terminal. I get an —INSERT— prompt and then anything I type after doesnt matter.

I know very little about Unix commands other than copying and pasting and what I can dig up on a quick google search. Im figuring that I am doing something or dont know something very elementary and would just like to get this to work.

Thank you guys/gals in advance

you miss “s” in command:
“tail -f /var/log/message”, it should be “tail -f /var/log/messages”

Thank so much for awesome post.

What are the reasons monit can not execute /etc/init.d/httpd service?

httpd is part of ‘root’ group.

Thanks,

I had the same problem as Marcus Herou. My lighttpd is showing as “Connection failed” and when I look in my access.log I see that lighttpd keeps returning 400. I have no idea why.

For Debian Linux see monitrc config file.

Hi.

My lighty instance only return 400 to monit. It is really strange since my app server with almost the same monit setup work flawlessly.

Any ideas ?

lighttpd-1.4.19 (compiled)
monit-4.8.1 (ubuntu-hardy)

It’s me, the last problem is resolved, it has something to do with working path. But here other question.: why I cann’t excute a shell files, the content like this:
1 cd /root/test
2 ./appname -m “param1″
