The problem relates to the phantomjs libraries that are used to export the images to a file.

Resolution

The resolution is to reinstall the phantomjs libraries on Nagios xi.

Establish a terminal session to your Nagios xi server and execute the following commands:

cd /tmp
rm -rf phantomjs*
uname -a

The output with either contain i686 or x86_64, this is required for the following file download.

Execute the following command to download the correct file:

i686

wget phantomjs-1.9.8-linux-i686.tar https://assets.nagios.com/downloads/nagiosxi/packages/phantomjs-1.9.8-linux-i686.tar

x86_64

wget phantomjs-1.9.8-linux-x86_64.tar https://assets.nagios.com/downloads/nagiosxi/packages/phantomjs-1.9.8-linux-x86_64.tar

Now execute the following commands to reinstall phantomjs:

tar xf phantomjs*.tar
mkdir -p /usr/local/nagiosxi/html/includes/components/highcharts/exporting-server/temp
/bin/cp -f phantomjs*/bin/phantomjs /usr/local/nagiosxi/html/includes/components/highcharts/exporting-server/
chown -R nagios:nagios /usr/local/nagiosxi/html/includes/components/highcharts/exporting-server
chmod 775 /usr/local/nagiosxi/html/includes/components/highcharts/exporting-server/temp

After executing these commands the graphs should now export successfully to images.
