NagViz issue

Post by ryanam »

Hi all,

I recently installed NagiosXI on a corporate RH VM and everything seems fine except that I'm unable to use NagViz. I saw no errors on installation -

Code: Select all

Not Found

The requested URL /nagvis/ was not found on this server.

Apache/2.2.15 (Red Hat) Server at noc01dev Port 80
What version of Nagios XI are you using? - Latest?? No version information in tar.gz filename.
Linux Distribution and version? Red Hat Enterprise Server release 6.4 (Santiago)
32 or 64bit? 64bit
VMware Image or Manual Install of XI? Manual, I guess. Don't really understnd the question. The install comes from - http://assets.nagios.com/downloads/nagi ... est.tar.gz
Are there special configurations on your system, ie; is Gnome installed? Are you using a proxy? Are you using SSL? Nothing additional

I'm not sure how much of the install.log is needed here at this point... like I said... no install errors from what I saw.

Anyone seen this?

Thanks

Additionally, this is the output of /etc/httpd/logs/error_log

Code: Select all

Which is strange because I just ran the install script for nagios xi like I did on a local VM (which worked).

172.23.0.136 is my LOCAL machine by the way... it's isn't the local host or a monitored node. Just the Windows 7 machine I'm working on.

Are you clicking on the nagvis link from Home > NagVis? What internal browser errors is it showing?

Hi,

Yes... doesn't even think about it. Just gives a white background with the old

Not Found

The requested URL /nagvis/ was not found on this server.

Apache/2.2.15 (Red Hat) Server at noc01dev Port 80

error message.

I'm actually on my own home PC now with a working instance of Nagvis... /var/www/html/nagviz (the path which the apache error log states as non-existent) doesn't exist on this machine either. Yet it works :\

Thanks

What does your apache vhost configuration for nagvis look like?

Do you know where this is by default?

I know that /etc/httpd/conf/httpd.conf is that standard config but does NagiosXI create one elsewhere?

Thanks

Run the following commands and show the output:

Code: Select all

ll /usr/local/nagvis/
cat /etc/httpd/conf.d/nagvis.conf

Hi,

Code: Select all

[root@noc01dev ~]# ll /usr/local/nagviz
ls: cannot access /usr/local/nagviz: No such file or directory

Code: Select all

[root@noc01dev ~]# cat /etc/httpd/conf.d/nagviz.conf
cat: /etc/httpd/conf.d/nagviz.conf: No such file or directory
I'll mention again that I did nothing differently here to what I did with the first VM I set up with NagiosXI and the other works perfectly.

I've also tried installing the component from here -

http://assets.nagios.com/downloads/nagi ... ith_XI.pdf

which completed without error.

Thanks

Not sure if this helps but here's the cat output for /etc/httpd/conf.d/nagiosxi.conf.

There's nothing in that location for Nagvis for some reason

Code: Select all

[root@noc01dev conf.d]# cat /etc/httpd/conf.d/nagiosxi.conf
<Directory "/usr/local/nagiosxi/html">
#  SSLRequireSSL
   Options None
   AllowOverride None
   Order allow,deny
   Allow from all
#  Order deny,allow
#  Deny from all
#  Allow from 127.0.0.1
#   AuthName "Nagios XI"
#   AuthType Basic
#   AuthUserFile /usr/local/nagiosxi/etc/htpasswd.users
#   Require valid-user
</Directory>

Alias /nagiosxi "/usr/local/nagiosxi/html"
[root@noc01dev conf.d]#

And one more piece of info... upon running ./usr/local/nagiosxi/html/includes/components/nagvis/install.sh, this happens - (I assume that the listed dependencies are missing...?)

Code: Select all
