Nagios Support Forum

Hi team,

We are trying to monitor one Nagios server from another Nagios server using Nagios XI Server config wizard. We are getting below error:

Error: Could not parse JSON from http://10.44.3.8/ ()

Could you please help here?

Hi,

It's possible that it is just timing out before it's getting any data back, you can edit the check in the CCM and add the following option See: Using The Core Config Manager For Service Management

If that does not resolve the error, please run the following check from the command line and post the output. Thanks, Benjamin

Hello,

Adding timeout in command definition didn't help.

Below is the output of another command.

HI,

Thanks for running that command, it's getting an HTTP error. Could there by a proxy running or firewall getting in the way.

Are you able to ping the XI server? Can you run a nmap to check the ports open on that address as well? Thanks, Benjamin

Hi,

Perfect, that looks good. What version is this XI server running? The API functionality might not be available on this system.

Thanks,
Benjamin

Hi,

I just had the same issue. The problem is that the script tries to get data from /api/v1..<etc>
But current location is /nagiosxi/api/v1..<etc>

I changed it in the php-file and this works on my side.

Regards, Edwin

Hello,

We are using Nagios XI 5.7.3.

Hi,

@@pingreply, Thank you!

Let's just make sure you have the latest version of the Nagios XI Server wizard, it should be 1.3.3. To confirm this go to Admin > System Extensions > Manage Config Wizards and scroll down to the XI Wizard.

If it's running the latest version, as suggested, try running the following API command to verify if you're able to get a valid return and let us know the results.
