I followed this tutorial https://www.howtoforge.com/tutorial/server-monitoring-with-munin-and-monit-on-ubuntu-14-04/2/ (for Monit only) exactly. I can access the Monit page outside ISPConfig at https://server1.example.com:2812/, but inside ISPConfig the iframe that should contain Monit is blank. I have filled in the System > Server Config fields for Monit correctly. The iframe html is: <iframe src="https://username: password@server1.example.com:2812/" width="100%" height="1000" frameborder="0" style="overflow:visible;" kwframeid="4"></iframe> I have added a space before 'password' to prevent [colon]p becoming ! I have tried this in Chrome, Firefox and Internet Explorer, with the same result in each. Any suggestions?
I haven't found anything relevant in syslog, ispconfig.log or the Apache error.log – is there anywhere else I should look?
Check this old post though I am not so sure whether it's similar to your case: https://www.howtoforge.com/community/threads/monit-page-is-blank.76160/#post-359136
Its probably your browser which prevents the content to be shown in the iframe. Current browsers don't like it when you pass auth information in an URL. There will be a workaround for that new browser nehaviour in ISPConfig 3.2.
