CPU Usage - No matching data to display

[jakai]

Hello,
After updating Nagios XI to version 5.8.7, we have a problem with displaying CPU Usage values in metrics. Can you please help how to fix this error? Are the other data displayed correctly (RAM, Disk, etc.)?

Thank you for help.

Hi Josef,

Thanks for getting in touch and welcome to the Customer Support Forum.

Do you recall what plugin or wizard you used to set up the CPU checks? I'd like to gather some data, can you run the tail command below, load this page and post the output.

Code: Select all

tail -f /var/log/httpd/*error_log

Lastly, please send over a system profile and we'll check the other logs as well.

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

Regards,
Benjamin

Hi,

I was able to replicate this on my test system and it's a bug. I should be able to get you a patch soon if you would like to correct this before the next release. Let me know.

Hi,

Update. To correct this, open the following file ( a good idea to save a backup to /tmp first):

Code: Select all

/usr/local/nagiosxi/html/includes/utils-metrics.inc.php

Change this line, around 708:

Code: Select all

            if(!empty($perfpartsb[3])) {
                $warn = $perfpartsb[3];
            } else {
                $display = 0;
            }

            if(!empty($perfpartsb[4])) {
                $crit = $perfpartsb[4];
            } else {
                $display = 0;
            }

            $use = floatval(str_replace(str_split('=%'), '', $perfpartsb[2]));

To:

Code: Select all

           if(!empty($perfpartsb[1])) {
                $warn = $perfpartsb[1];
            } else {
                $display = 0;
            }

            if(!empty($perfpartsb[2])) {
                $crit = $perfpartsb[2];
            } else {
                $display = 0;
            }

            $use = floatval(str_replace(str_split("'percent'=%"), '', $perfpartsb[0]));

Let me know if that resolves the issue.
