NagVis not working JSON error

[tpwebb]

Hello,

I have upgraded our test environment to Centos 8 and installed manually NagiosXI, there were no errors to this install, I have also restored our production backup file onto this system and it is working.

I am currently running version 5.7.1

I currently have an issue with NagVis when opening it from the menu selection, it comes up with a "Invalid JSON response"


I see you have a fix in 5.7.2 for NagVis, for a Python 3 issue, will this resolve what I have described above?

Regards
Terrence.

Hello

Turns out that 5.7.2 does fix this problem, however

I now have 2 remaining issues to resolve.

1. After the upgrade I have lost all my maps and presented with the demo maps, I would like to get my maps back?

2 I have a second problem, the monitoring engine will not start, can you also assist?

Thanks again

Terrence

It would be best if you could open a new thread for each unique issue. I'll leave it to you to decide which to address on this thread.

Regarding the Nagvis problem, you may need to restore the /usr/local/nagvis directory. This directory holds all nagvis configuration and it sounds like it may no longer be readable or the config is gone. The backups should contain a copy of it howerver.

For the monitoring engine not starting issue, what errors are you seeing and where exactly? Try starting it directly on the command line with:

Code: Select all

/usr/local/nagios/bin/nagios /usr/local/nagios/etc/nagios.cfg

Hello,

Thanks for your reply, lets keep this for the Nagvis problem and I will create another for the monitoring problem.

I have copied the folder from the old to the new and have the entries back but now remain with the JSON error.

Can you assist?

Thanks

Please provide a screenshot showing the error and PM a copy of the nagvis directory as well as a copy of the current CCM configuration. The CCM config can be gathered with:

Code: Select all

mysqldump -uroot -pnagiosxi nagiosql > ccm.sql

Please PM the ccm.sql that the above command creates.

Hello,

Attached is a copy of the error that Nagvis is getting.

I will send the other information in a PM to you.

I was able to get it to load on a test machine. I will PM a copy of the directory to you to test with. Copy it to the XI machine and then extract it with:

Code: Select all

tar -xzvf nagvis.tar.gz -C /usr/local/

Thanks.

The initial issue was fixed with an upgrade to 5.7.2.
