Monitoring Raspberry Pi
Before commissioning the Raspberry Pi; it would be nice if we setup some monitoring; so we can correlate any issue in the field with device status. This becomes important especially for devices like Raspberry Pi that has limited resources. The simplest and easiest way is to setup SNMP; its the protocol to collect and organize information about the managed devices on IP networks. Given Raspbian is a just another Linux; we can easily setup SNMPD; a SNMP daemon; and can monitor the device remotely or even from within the device. To install SNMPD; issue the following commands; and once installed backup the /etc/snmp/snmpd.conf
