Downloading the check_jmx plugin

1. Change the directory to your home directory:

   cd ~

2. Download the check_jmx plugin:

   wget -O check_jmx.tgz "https://exchange.nagios.org/components/com_mtree/attachment.php?link_id=1274&cf_id=24"

3. Extract the downloaded plugin:

   tar xvf check_jmx.tgz

4. Move the plugin to /usr/local/nagios/libexec/ directory:

   sudo mv check_jmx /usr/local/nagios/libexec/

5. Update the file /usr/local/nagios/libexec/check_jmx/nagios/plugin/check_jmx to enclose the $@ with double quotation marks:

   "$@"

   Thus the whole java line will become:

   java -cp $RDIR/jmxquery.jar org.nagios.JMXQuery "$@"

   The use of the double quote is to handle space character properly
