Monit appears to be working on command line but get 404 'There is no service by that name' in web interface [closed]

Question

Monit seems to be working, but when I go to the web interface at port :2812 I get

-->:/var/log$ sudo monit -t
Control file syntax OK
-->:/var/log$ sudo monit status
The Monit daemon 5.2.5 uptime: 11m 

System 'system_mydomain.net'

Any ideas what would cause this?

Answer 1

I couldn't get this working so that all external IPs could access the web interface.

In the end I used Apache:

<VirtualHost *:80>
    ServerName monit.yourdomain.com
    ProxyPass / http://localhost:2812/
    ProxyPassReverse / http://localhost:2813/
    ProxyPreserveHost On
    <Proxy>
        Order allow,deny
        Allow from all
    </Proxy>
</VirtualHost>

You need the proxy and proxy_http mods enabled for this to work.

Probably your configuration is SSL enabled but you have not generated the private certificate for HTTPS.

If you do not care about security in your context, open /etc/monit/monitrc and replace the existing httpd section with

set httpd port 2812 and
   allow localhost
   allow admin:test

After a monit deamon restart, you should be able to connect to http://localhost:2812/ with admin user and password test.

To allow access from anywhere, you have to use allow 0.0.0.0/0.0.0.0

Please refer to monit httpd documentation section for full details.

If you want SSL enabled, you will have to generate a SSL self-signed certificate at /etc/certs/monit.pem thanks to the following procedure, for instance.
