Hello,

we have the same issue, that was described here: https://support.nagios.com/forum/viewto ... 16&t=54669

The permissions seme to be correct:

Code: Select all

root@ux010162:/usr/local/nagiosxi# ls -lad /usr/local/nagiosxi/tmp                                                       
drwsrwsr-x 4 root nagios 12288 Nov 19 15:26 /usr/local/nagiosxi/tmp

Even with 777 the message remains the same:

Couldn't create temporary file. Check that the directory permissions for the /usr/local/nagiosxi/tmp directory are set to 775.

What can we do?

Best regards
Christoph

By chance are you on a 32 bit system?

Code: Select all

uname -a

Lets try this
in /usr/local/nagiosxi/html/includes/components/graphexplorer/templates/perfdata.inc.php on line 112
change this

Code: Select all

$start = (int) $args['start'];

to this

Code: Select all

$start = $args['start'];

then try again.

Please let us know if this resolves the issue

Thank you for your quick response!

Code: Select all

root@ux010162:/usr/local/nagiosxi/tmp# uname -a
Linux ux010162.noweda.de 2.6.32-754.17.1.el6.x86_64 #1 SMP Tue Jul 2 12:42:48 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

I changed line 112 as described - no effect.

But I realized something else:
1. With another host it works! I'm able to download CSV, JSON and XML from another host
2. When I try to download CSV, JSON or XML from one of the affected hosts, zero bytes files are created in tmp-dir:

Code: Select all

root@ux010162:/usr/local/nagiosxi/tmp# ll -atr *.csv
-rw-r--r-- 1 apache nagios 0 Nov 19 16:01 04144217b6bf04faaee771d0a77dfdcd.csv
-rw-r--r-- 1 apache nagios 0 Nov 19 16:04 d553fd4d045fd23181b8a69cfeb8ecc4.csv

Try this:

Code: Select all

chown -R apache.nagios /usr/local/nagiosxi/tmp
chmod 6775 /usr/local/nagiosxi/tmp
service httpd restart

Please run this tail command as root (and leave it running):

Code: Select all

tail -Fn0 /usr/local/nagiosxi/var/cmdsubsys.log /usr/local/nagiosxi/var/load_url.log /usr/local/nagiosxi/var/eventman.log /var/log/httpd/error_log /var/log/httpd/ssl_error_log

Then try to download again and send us the full output after it has failed.

What is the output of this command?

Code: Select all

ls -lh /usr/local/nagiosxi/html/includes/components/highcharts/exporting-server/temp

Please send the exact hostname/servicename and the exact place you are trying to do this in the web GUI so that we can look into it more.

This could be related:

Code: Select all

ERROR: No DS called '3' in '/usr/local/nagios/share/perfdata/AC010024/_HOST_.rrd'

Please attach that file as well so that I can query it.

Thank you for those files. What are the names of the hosts or services that you are trying to get the data for?

Posted: **Thu Nov 21, 2019 3:07 pm**

Hello,

the host is SR010080 and we are trying to download the ping performance graph (host check).

Best regards

It looks like the RRD file only has 2 datapoints but I would guess that the .xml file has 3 and that is causing the error.

Delete the .rrd file and the .xml file for that host and let it recreate it and see if you can download the csv file then.
