Invalid argument supplied for foreach()

Yesterday I upgraded Nagios XI to 5.7.1 and as soon as it came backup the service checks for Nagios XI Daemons and Nagios XI Jobs started alerting as "Unknown". I ran the service check from command line to see if there was more detail and I received this warning:

PHP Warning: Invalid argument supplied for foreach() in /usr/local/nagios/libexec/check_nagiosxiserver.php on line 136

That is the same result for each of the service checks. I do not know enough about PHP to start messing with the script.

Any thoughts?

Hello,

We re-wrote the backend database software in Nagios XI, so if your server has a check for the ndo2db service, you can safely delete that check in the Core Configuration Manager (CCM).

The PHP message is just a warning, so it's hard to say if that is the direct cause of the error. If you continue to get an unknown condition for the Nagios jobs make sure the IP address and apikey has not changed then send me your system profile and I'll take a closer look at the logs.

To send us your system profile.
Login to the Nagios XI GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button
Save the profile.zip file and share in a private message or upload it to the post/ticket, and then reply to this post to bring it up in the queue.

Hello,

My apologies, due to security and spam, you need a post count of 2 or higher to send a profile. Can you try once more? Thanks!

You need to click the Download Profile button which will give you a profile.zip file, not the View System Info button.

Please attach that profile.zip.

Thank you!

While likely unrelated, I'm seeing this:

Code: Select all

[Tue Jun 16 09:34:21.418792 2020] [:error] [pid 9036] [client X.X.43.213:25709] PHP Warning:  require_once(/usr/local/nagiosxi/html/includes/utils-sounds.inc.php): failed to open stream: No such file or directory in /usr/local/nagiosxi/html/includes/utils.inc.php on line 39, referer: http://XXXXXXX/nagiosxi/includes/page-home-main.php?&=
To fix that do this:

Code: Select all

cd /tmp
rm -rf /tmp/nagiosxi
wget https://assets.nagios.com/downloads/nagiosxi/5/xi-5.7.1.tar.gz
tar zxf xi-5.7.1.tar.gz

chown nagios.nagios /tmp/nagiosxi/nagiosxi/basedir/html/includes/utils-sounds.inc.php
chmod 0644 /tmp/nagiosxi/nagiosxi/basedir/html/includes/utils-sounds.inc.php

Did you have any errors during the upgrade? Can you post the full upgrade.log? I'm thinking this file also wasn't updated, please attach it:

Code: Select all

That looks good.

Please attach this file:

Code: Select all

/usr/local/nagiosxi/cron/sysstat.php
Or compare yours with the one I've attached and replace yours if it differs. Then wait 10 minutes and see if it's now working.
