Nagvis doesn't work in Nagios XI

[mohans_15]

Dear Experts,

I am using Nagios XI 2014 R2 and I am trying to use Nagvis.

In the nagios documentation, I read that Nagvis gets installed by default during the Nagios XI installation.

But I am unable to view any maps rather the nagvis page gives an error when I try to access as below:

Not Found

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

Apache/2.2.15 (Red Hat) Server at cbq2-svu-nagxi1 Port 443

I tried running the install script with root access but I received a permission denied error.

Can you please guide me to check if the nagvis process is running or if it is installed first of all?


Regards

Mohan

From the Nagios XI machine, can you try running wget http://127.0.0.1/nagvis/ and post the result?

It should show you this -

Code: Select all

[root@suse11 etc]# wget http://127.0.0.1/nagvis/
--2016-01-19 09:21:39--  http://127.0.0.1/nagvis/
Connecting to 127.0.0.1:80... connected.
HTTP request sent, awaiting response... 401 Authorization Required
Authorization failed.
[root@suse11 etc]#

It should be included in your system by default as you mentioned. Was the system upgraded from a version prior to 2012?

[mohans_15]

No, it was a fresh installation of Nagios XI 2014.

From the local machine, I believe Nagvis is installed and working it seems on port 80.

Code: Select all

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

Apache/2.2.15 (Red Hat) Server at cbq2-svu-nagxi1 Port 443

Are you able to access it over http from your machine?

[mohans_15]

No, it is not working over http as well.

Odd, can you post your nagvis apache configuration?

Code: Select all

/etc/httpd/conf.d/nagvis.conf

[mohans_15]

I don't see this file in the given directory. Please find below:

[root@cbq2-svu-nagxi1 conf.d]# pwd
/etc/httpd/conf.d

First of all, set up your proxy according to our recommendations posted on our FAQ wiki page:

https://support.nagios.com/wiki/index.p ... th_Proxies

I am not sure why NagVis was not installed with XI - it is shipped with XI and it is present on my test XI 2014R2.7 box...

Try force upgrade on all addons (components, wizards, dashlets, etc.) by running:

Code: Select all

cd /tmp/nagiosxi
./upgrade -f

Note: Backup your Nagios XI server prior to force-upgrading the addons.

See if NagVis will reinstall properly.
