Abstract

The Raspberry Pi is a single-board computer that can be used in many network related operations due to its low cost, size and high versatility. SNMP protocol is used to monitor dedicated network devices and systems both Windows and Linux. Raspberry Pi can be used to monitor the network as a SNMP agent. There are, however, two aspects that may have a performance impact on a low computing power system: encryption and the polling interval. SNMP version 3 is the recommended SNMP version and allows the use of encrypted messages to increase the network management security but needs more processing power. It is also possible to shorten the polling interval for the SNMP information in order to better detect fast changing network characteristics, but this can become a stressful operation. This paper will test the usability of Raspberry Pi as a SNMPv3 agent with encryption support for default and fast refresh interval.
