Why does error while converting SVG Nagios occur

Normally, you come across this error message when saving a performance graph as a PNG, JPEG image in Nagios XI.

Sometimes, you may also see the below error message is logged in /var/log/httpd/error_log:

sh: ./phantomjs: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

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

How we fix the error while converting SVG Nagios

Now let’s see how our Support Engineers resolve this error message to our customers.

In order to fix this error, we suggest reinstalling the phantomjs libraries on Nagios XI.

For that, first, establish a terminal session to your Nagios XI server and run the below commands.

# cd /tmp
# rm -rf phantomjs*
# uname -a

As a result, the output will either contain i686 or x86_64. This is necessary for the following file download.

Now, run the below command to download the right 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

After that, run the below 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

Once you execute the above commands, the graph should now export successfully to images.
