Nagios Support Forum

Hi ,

Seem to have a small Using the Linux Configuration wizard. We are using it to config for a RHEL server (no other linux os types to test).
I can can configure a server with the NCPA wizard ,
however when I use the Linux Configuration wizard , it appears to not complete the page rendering ( I've attached a page image ) .
As you can see, incomplete and missing navigation buttons. The only thing we can do at that point, reload the page which starts the wizard over.

I know we can just use the generic NCPA wizard , but would like to just resolve this for other team members.

has anyone else experienced this ? is is a Bug and is there Fix ?

Details:
Nagios XI Version: 2024R1.4.1 running on RHEL 9.5
NCPA Version: 3.1.3 running on RHEL 8.10

Thanks,
DBFox

Hi @DBAFOX,

Thanks for reaching out.

Would you please run the following command in a terminal session? ... then navigate to Step 2 again (or reload the inner frame) and let us know if the tail spits out any errors?

the screen is now showing me something different -- a gateway timeout message (all black -- had to highlight the text to see it )

On another server -- we get to step #2 -- same visual output --
here is the tail -f command output

Hi @DBAFOX,

It is likely the PHP Fatal error's that are causing the problem. I will create an issue so the developers can take a look at it.

If it is a Gateway Timeout, there may be some issue between the XI server and the NCPA server.

Just to clarify, are you having this issue with the Linux Server wizard, the Linux Server (legacy) wizard or something else?

Hi @lgute ,

It is with the Linux Wizard (using NCPA ) . We are not using NRPE .

It happens pretty consistently. I think i know what the gateway issue is with the NCPA -- we can disregard that for now.

Thank you for your assistance, let me know if you need anything else

Sincerely,
DBAFox
