Nagios CORE commands failing from XI web interface

[BenCowan]

RHEL9 w/Nagios XI version 2024R1.1.4

I upgraded last week but just noticed that I was unable to issue commands via the web interface. For example Home->Tactical Overview->Notifications I' receive errors attempting to ENABLE/DISABLE anything. The following error was prevalent in the logs so I commented out a block of code (lines 315 to 320) and now it's working, however, I have no idea what I may have broken by doing this.

We use grab_request_vars in many locations so its best to not comment out this code. I'm not sure what your line 315 looks like but it seems like there isn't a guard for if that array key exists. If you want to get rid of the warning you mentioned above and you feel fine updating the code you can change line 315 to this:

Code: Select all

    if (array_key_exists('REQUEST_METHOD', $_SERVER) && $_SERVER['REQUEST_METHOD'] == "PUT") {

Let us know if this fixes your issue.

That worked great. Thanks. Will that alternate code be in future upgrades?

@BenCowan,

Yes, this change will be included in future updates.

Excellent.

Hey @rosydam

I saw you quoted the response above. Are you still having similar issues?

If Nagios CORE commands are failing when executed through the Nagios XI web interface, but work via the command line, it’s often related to permissions, configuration issues, or web interface settings. incredibox sprunki
