Reports section on side bar

[sinkak]

its direct to public ip of server

[tmcdonald]

Does it work if you use the internal IP address from within the network? You should try that, either through a VPN or some other method. It almost sounds like there is a network device somewhere in the Internet between you and the Nagios server that is acting up.

[sinkak]

even if i am on VPN. Internal ip in browser wont work. I may have a routing issue.
But on the server. all inbound and outbound traffic is open. for ports 443 and 80.
does the reports come from any special port?

[sinkak]

can this be a memory / CPU issue?

[jolson]

Try accessing the reports, and then check on the apache access log - that is typically where you can find a useful error:

Code: Select all

tail -100 /var/log/apache2/access.log

can this be a memory / CPU issue?

It's likely not a CPU/memory issue, you can certainly check on them to ensure they aren't being stressed:

Code: Select all

sar
free -m
top | head -n5

does the reports come from any special port?

Nope - the reports come over the same port you're using to access Nagios with. I think that whatever problem you're having is on the back end of Nagios - the access logs may give us some hints.

Can you please take a look at this post and see if this solution may be something that works for you?

Did one additional modification now:

Moved the nagios .cgis into cgi-bin/nagios and modified the nagios.conf accordingly.
so it looks like this now:

Code: Select all

ScriptAlias /nagios/cgi-bin "/var/www/vhosts/myserver/httpdocs/cgi-bin/nagios"
#ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
#<Directory "/usr/local/nagios/sbin">
<Directory "/var/www/vhosts/myserver/httpdocs/cgi-bin/nagios">

Code: Select all

$ls -l /var/www/vhosts/myserver/httpdocs/cgi-bin/nagios

If you're using Firefox/Chrome do you see anything in the "Network" section of the Developer Tools/Firebug console? (F12)
