======Overview======
The agent configuration is pretty simple and composed by couple files in:

/usr/local/nagios


=====Deploy new plugin=====
The configuration of a new plugin is done pretty simple. There are many available scripts for GPL use which can be downloaded for free.

====Monitor ASM====
The plugin: ASM_CHECK is able to monitor the ASM instance as follows:

===Change the config file===
<sxh bash>
[root@oraback etc]# cat /usr/local/nagios/etc/nrpe.cfg
----
#command[check_procs]=/usr/local/nagios/libexec/check_procs -w $ARG1$ -c $ARG2$ -s $ARG3$
command[check_mem]=/usr/local/nagios/libexec/custom_check_mem -w $ARG1$ -c $ARG2$
command[check_asm]=/usr/bin/perl /usr/local/nagios/libexec/asm_check.perl --asm_home=$ARG1$ --action=usedspace  --threshold DATA=$ARG2$
</sxh>

The syntax is very simple:

command[command_name]=script --script_ARG1=$nagios_ARG1$ --script_ARG2=$nagios_ARG2$ --script_ARG3=$nagios_ARG3$


The nagios argument should be passed in the CORE server, when the script argument are passed in the configuration file of the agent.


====Post-Configuration====
The next step is to configure the CORE server to recognise this configuration.
