Configure the Nagios plugin to monitor the sample applications - 6.5

Create a local directory for the configuration files if it does not exist, for example: /usr/local/nagios/etc/objects/ or /etc/nagios3/etc/objects/, depending on where your installation expects them.

Define jolokia_host (the host where the examples are running) in /etc/hosts - this name is used in subsequent files, rather than hard-coding in the ip address. For example, add the line (depending on the IP address):

192.168.1.101 jolokia_host

Copy the template and sample configuration files into Nagios etc/objects subdirectory. Not all of these are needed for this example, but we will only reference the ones we need in the configuration files. For example:

cp -f <TalendRuntimePath>/add-ons/adapters/nagios/template/*.cfg
						/usr/local/nagios/etc/objects/

cp -f <TalendRuntimePath>/add-ons/adapters/nagios/sample/*.cfg
						/usr/local/nagios/etc/objects/

This target directory may be elsewhere in your installation, for example: /etc/nagios3/etc/objects/.

Add the template configuration file to the existing nagios.cfg, here are some examples, which depend on where your installation puts config files:

In /usr/local/nagios/etc/nagios.cfg add:

cfg_file=/usr/local/nagios/etc/objects/jmx_commands.cfg
cfg_file=/usr/local/nagios/etc/objects/camel_host.cfg

Or in /etc/nagios3/nagios.cfg add:

cfg_file=/etc/nagios3/etc/objects/jmx_commands.cfg
cfg_file=/etc/nagios3/etc/objects/camel_host.cfg

Define macros which will be used by jmx_commands.cfg in resource.cfg, here are some examples, which depend on where your installation puts config files:

In /usr/local/nagios/etc/resource.cfg add these lines:

# set the path which jmx4perl plugin installed
$USER5$=/usr/local/src/jmx4perl/scripts
# set the path to where to find configuration files
$USER6$=/usr/local/nagios/etc/objects

Or in /etc/nagios3/resource.cfg add these lines:

# set the path which jmx4perl plugin installed
$USER5$=/usr/local/src/jmx4perl/scripts
# set the path to where to find configuration files
$USER6$=/etc/nagios3/etc/objects

Then, restart Nagios for the changes to take effect.

# service nagios restart

Note: the name of this service may vary, depending on which package you used to install Nagios, so it may be called, for example, nagios3, instead of nagios.
