Hi @jorgeaaq,

Thanks for reaching out and reporting this issue. I will check it out.

Hi @jorgeaaq,

With the resources you have for your XI server, I am surprised you are having performance issues. How is your disk space and how many hosts & services are you monitoring?

Lauira

is a big installation

around 6,000 hosts and 9,000 services

In addition to a slow response time, reports stopped generating, and I had to extend the timeouts to get them to generate.

I don't know how much this error has to do with it and how much it has to do with the recent hosts and services we've added.

I hope this information helps

Hi @jorgeaaq,

This may be a more complicated issue than can be addressed in this forum. To get more help, please open a support ticket here: https://support.nagios.com/, so our support team can help you.

The error messages in your Nagios XI logs indicate that the PHP code is trying to access array keys ("id", "title", "opts") that don't exist in some arrays. This is happening in the utils-dashboards.inc.php and utils-menu.inc.php files. While these errors might not directly cause slowness, they can indicate a problem with the dashboard or menu configuration.

Here are some steps you can try to resolve this:

1. Check Custom Dashboards/Menus: If you've created any custom dashboards or menu items, review their configuration. Make sure the arrays used to define them are correctly structured and contain the necessary "id", "title", and "opts" keys. A mistake in your configuration could cause this error.
2. Repair Database: Sometimes, database issues can cause these types of errors. Try running the Nagios XI database repair script. You can usually find this script in the Nagios XI documentation or support forums.
3. Reinstall/Upgrade: Although you upgraded, it might be worth trying to reinstall Nagios XI or upgrade to the latest version again to ensure all files are correctly updated and configured. Be sure to back up your data first.
4. Check Nagios XI Forums/Support: Search the Nagios XI support forums or contact Nagios XI support directly. These errors are common, and there may be known solutions or patches available. Provide them with the error logs and system information you posted here.
5. PHP Version Compatibility: Verify that the version of PHP running on your system is compatible with your version of Nagios XI. Sometimes, PHP version issues can cause unexpected errors.

It's important to address these errors, even if they don't seem to be directly causing the slowness, as they can potentially lead to other issues in the future.

Do you think the performance issue when monitoring large scale like 6,000 hosts and 9,000 services in Nagios mainly comes from system configuration, or from software architecture limitations? If you encounter this situation, will you optimize internally or consider opening a support ticket immediately?
