still can't access nagvis

[lilydalehs]

Hello Support,

ever since I created a new Ubuntu 20.04 and upgraded to 5.7 I have been unable to access nagvis.

After being told late July that 5.7.3 would fix my issue, today I've upgraded to 5.7.3 and still no joy.

Whenever I click on nagvis from the homepage menu, all I get is

Code: Select all

You are not permitted to access this page (Overview/view/).

Can you please advise how I can get this working?

Thanks,
Chris.

PS the original thread was https://support.nagios.com/forum/viewto ... 16&t=59215

Please perform these steps:

cd /usr/local/nagiosxi/html/includes/components/nagvis
tar zxf nagvis-1.9.8-nagios.tar.gz
cp -p nagvis-1.9.8-nagios/nagvis-make-admin /usr/local/nagvis/etc
cd /usr/local/nagvis/etc
./nagvis-make-admin nagiosadmin

Then login as nagiosadmin, go to Home > Nagvis:
- Click User Menu > Manage Users
- Under the Modify User row edit one of the users (not nagiosadmin)
- Add Users (read-only) to the right hand column
- Hit Save

Now logout and log back in and test and the other users. That worked for me on Ubuntu 20.

Hi ssax,

thanks for the response. I did all that, which seemed to work ok. When I login I get a page with Map Index and Rotation Pools.

However, when I click any of the "demo" maps I get the following error. All the other pages appear to work ok but none of the demo maps will open.

Cheers,
Chris.

This seems to be a nagvis bug with PHP 7.4, please implement these changes and it should fix your issue:
- I only ran into the first bug listed, that should fix yours, you may want to do both

Hi ssax,

thanks for the response.

I made both the changes that were indicated in that document, and I ended up right back where I started, with

Code: Select all

You are not permitted to access this page (Overview/view/).

So I removed the second of the changes on the page, and just used the first one mentioned, and now it seems to be working.

Thanks,
Chris.

[ssax]

Awesome, thank you for posting the update, I'll let the devs know that second one breaks it. Let us know when we're okay to close this and mark it as resolved.

[lilydalehs]

Happy to close it now.

Thanks for the assistance.
