You are now going to define a data template for the host MIB hrSystemProcesses. Although a data template already exists for this, this task provides a good example of how to create SNMP-based data templates. For this to work, let's assume that your CentOS-based Cacti server is already configured with an SNMP daemon. You can check your box with the following command:

[root@localhost ~]# snmpwalk -On -c public -v 2c localhost HOST-RESOURCES-MIB::hrSystemProcesses.0
